Lawnmower for sale. Runs excellent. Has rebuilt engine. (20 times over)

I'm a mechanical engineer at Texas A&M. Project farm always makes me smile with his attention to detail, his consistent procedures, honest and unbiased results, and logical/practical methods. What I learn from channels like these is on par with what i get in class. Thank you for your professionalism. Keep it up!

Hi. I like your approach very much for the testing. I can share some experience with you, having been an engine test and development engineer for BM from Brasil. Our main task there was adapting the engines for the Brazilian fuel mixture (up to 25% ethanol or even 100% ethanol). Out of all materials, durability, efficiency and wear testing done on my time there, some very nice evidences came out 1 - Up to a certain ammount of ethanol (the 10% you use here) engines are indeed more efficient - ethanol burns very efficiently, unlike the other detonation inhibitors used. But the detergent/cleaning properties ot the ethanol on carbon deposits are not so pronounced. 2 - the more ethanol you add, harder it will be on engine starting at cold weather. That is why North America stuck with the 10% mark. At 15% is hard to start anything below -15C. Since this extreme cold is never found in Brasil, they chose to increase ethanol content, so the cleaning benefits of the alchool are more evident. I tested 25% ethanol engines that, after more than 10k hours of endurance, looked like a 1-3K used pure gasoline engine, when it comes to carbon and slug deposit. The 100% ethanol engines did not built carbon at all. 3 - YES, any rubber that has a particular base material (If memory serves, any fluor-based rubber) WILL degrade VERY rapidly when using ethanol. All manufacturers that habe been to Brail sellin cars KNOW that. We spend pretty much a decade testing and adapting rubbers and metallic parts to resist the corrosion. So... in new engines this will not be an issue. BUT if you use ethanol in a very old engine (like one with a CARBURATOR), you will likely see the rubber degradation, since those engines may not have the enhanced rubber and metallic coating found today. 4 - Ethanol performance as a carbon deposit inhibiter is not as good on 2-stroke engines Since you actually burn a mixture of gasoline and oil, due to the very nature of the cycle. Hope that helps your quest.

Love your videos. Absolutely excellent. The reason the water-ethanol volume was not 30 mL was likely due to partial molal volumes. When two miscible liquids are mixed the total volume does not often equal the sum of the volumes. This is due to packing and molecular attractions ( hydrogen bonding , Vander Waals attractions, etc). I am a research organic chemist but again your work is really great!!

As a test engineer I well know that nothing is more instructive than testing something to directly see the outcome. We even learn from our mistakes! I love how thorough you are and how thoughtfully planned your experiments are. This is science for everyone. Thanks!

As a Subaru Technician in Australia we find that E10 fuel Leaves deposits on fuel injectors and eats away at platinum spark plugs a standard plug gap can go from 1.1mm at factory to 3mm in 112,500 km(sometimes within 50,000km) with the electrode being eaten away. The same spark plug type with non ethanol fuel is dirty but not damaged in any way over the same 112,500km . The money saved by using E10 is spent on more costs at you dealership or workshop due to poor quality fuel. This is a great Channel. Keep up the good work.

You are a pure genius, the testing methods, your video production are first class. I worked in a car dealership the ethanol attacks rubber orings and leaves sediment, burns cooler there fire reducing vehicle fuel efficiency by typically by 10 percent. I also worked as a small engine tech, customers would bring in the outdoor equipment, it loses power, won't start, etc. I learned ethanol settles and breaks down after 30 days. I would find white powdery substance or looked like snot, used brakekleen blew it the passages and cleaned the fuel bowl. Steam the carb then run bread tie in the ports. Reassemble test and done. Asked the customer if used ethanol? They use ethanol in everything never have a problem. At the dealership I worked at and my friend another the service advisor ask where do you get your gas or do you use ethanol? He would tell them try using brand name gas station and switch to regular gas. Will give you gas card if no difference. They thanked him. When gas hut 5 a gallon here I used ethanol I paid the price, my Silverado with tuned 5.3 started losing power going up hills or long inclined felt jerking sensation. My winter beater Buick and for fun Cadillac the same. My toy 83 monte with 454 filled up with ethanol as left the station it fell on its face. My Nova SS with high strung 406 small block pinged horribly. Live and learn.i know I use it in everything runs fine I bet. Thank you for the bideo

Simply one of the best channels on KZfaq. He does what we'd all like to see done, and does it very well. A huge thanks.

Personal experience: Having dealt with various carb issues previously, I've been using strictly non-ethanol 91 in all my small engines, both 2- and 4-cycle, for about four years now - mower, snowblower, power washer, grass trimmer, chain saw, leaf blower, etc. I don't use any fuel stabilizers and have had no carb issues with any piece of equipment since I switched. (mower is 11 years old, snowblower is 27 years old).

“I haven’t owned it long enough to recommend it.”-words of wisdom

I use ethanol-free gasoline in my lawn mower because there’s less risk of it drawing water from the air. I’ve had problems with carburetor internal corrosion when I’ve left ethanol-containing gasoline in a lawn mower over the winter. But more recently I’ve been completely draining the fuel tank and running the engine until it clears the carburetor, before stowing the lawn mower for winter. Thanks for the very informative practical test you’ve shared!

Just the work he puts into doing all these experiments is mindblowing!! My friends and I tried 2 and was just glad it was over, same conditions but more people working on the projects! There is so much work as he cuts a LOT out in his presentations! Better Him than us. Just Great work. Aussie chris 🇦🇺

In Alaska ethanol blended fuel at the general pump is banned because it pollutes the waters by corroding seals/lines in marine equipment. To sell any ethanol blend it has to be at a proprietary pump and clearly labeled.

Nice generator, Project Farm has cool toys. 4% better fuel efficiency is exactly as expected: ethanol has ~60% of the heat energy per volume compared to gasoline. So E10 with 10% ethanol has 96% the heat energy of pure gasoline per volume. And ethanol free E0 gas has a much longer shelf life. For all occasional use engines, E0 ethanol free seems a smarter idea.

I was using reg unleaded several years ago and I found that ever 2-3 years I was having carb issues and then at Q-Trip came out with e91 which is non ethanol premium and to this day I've had no carb issues and that's been 15 years not only I use it in my mowers but I also use it in the vehicles. Thanks for all your testing and as always be safe 👍

Your testing is awesome, love how you look at so many angles of testing, unbiased :)

PF- I'm an old dude and I gotta tell ya that was one of the best all round mechanical video's I've ever had the pleasure of watching! Nice brisk pace! Thank You, you kept informed all the time what you were doing and what was going on, solid common sense and no nonsense, really professional, and I felt totally confident of all your results and conclusions! Bang on, and that Electric Start was comical too !!! Please keep making your video's!

my biggest issue with ethanol is, they use lower oct gas, put 10% corn fuel in it, and charge ya the same price. so your getting cheaper gas but paying the same for it.

first, thank you for making these vids. they are very helpful. one place where its easy to see the difference that ethanol makes is in 2 stroke outboards. not only corrosion in the tanks but also the rubber and plastic in the fuel systems are damaged. the real problem happens when the particles make their way thru the crankcase on their way to the cylinders. most shops will have a wall of 2 stroke outboards waiting to be rebuilt. most of the symptoms follow a pattern that you can read loosely based on time and amount of ethanol. I tell anybody who brings me one to work on that if they can afford me working on it then they can afford the better fuel.

I’m so thankful for the tedious and focused work you do to answer serious questions that make a difference in our lives.👍❤️

I deliver fuel in New York to gas station and when I deliver that 85 It’s always about 2000 gallons to the station so I put it in the same compartment and the seals wear out on my discharge valve because of that I have five of them on my Tanker And it’s always comparment number three that the seals we’ar out on

I've been told ethanol fuel degrades seals/gaskets quicker. Maybe hoses too. *edit* I made this comment 1 minute before the end when he said he'd check the effects on plastic and rubber parts. This guy is great!

When I’m at the pump, I usually get the cheapest fuel, which ends up being ethanol10. What most people don’t know is that, although you spend less money on the fuel today, you’ll be back at the pump quicker due to a loss of efficiency. The price and efficiency determine if its worth getting the cheaper fuel. Great video!

Thanks for the video. In France sp98 is almost 2€/l and E85 is 0,8€/l that's why people use ethanol instead of pure gazoline. All of my Toyota hybrid owner friends are on 100% e85 without any pb. Sorry for my bad english Antoine

As a small engine mechanic, i can definitely say that yes ethanol is damaging to materials like rubber o-rings and hoses. Besides that it corrodes aluminium, rusts steel, and creates a chalky buildup that ruins carburetors. Aaaaand..... It has a lower energy so e-10 fuel is roughly 10% less fuel efficient than straight gas and takes roughly 30% more fossil fuels to create.

I love you added an engine with efi. Well done!

Very informative video, thank you! I learned my lesson last year with my Ariens snow blower up here in Kennebunk, Maine. The carb was drained for the season, refueled with 10% ethanol gas from Sunoco and within one month it gunked up and wouldn't start. Took the carb off, cleaned it out and now only use "ethanol free" gas. Engine has more power and less exhaust fumes. Will neve use regular gas again in small engines. Also, just put my 2016 Mazda Miata away for the Winter, filled the tank with ethanol free gas. Our winters don't end until June around here. Again, great video! Thank you!

Did you ever get around to doing the long term test of ethanol fuel vs non ethanol on plastic and rubber components? It's been about 3 years now.

Excellent! That said my main concern with ethanol use in small engines is the corrosive effect it has on carb parts, etc, as well as causing rubber gaskets etc to fail.

Pros and Cons of E0 vs E10 E0: +More energy = higher MPG +No phase separation = long shelf life -- Costs more -- Not sold in my state *** (Not once seen it being sold at any pumps in the state, but it is sold at some places) E10 +Cheaper +Better "tailpipe" emissions (I'd rather breathe E10 exhaust then E0 exhaust) +Works as a very good long term engine cleaner --Corrosive and attracts water --Not sustainable, also funds monocrop agriculture --Worse mileage --Higher volatility can cause vaporlock

Thanks for all your work putting some great, informative videos together. They have been a lot of help in decision making for me. In regard to ethanol gas issue, I've been driving the same car since before ethanol and can tell you that my milage dropped from 18-19 mpg to 15 when ethanol was added the gas.

Ethanol needs more fuel flow to run stoichiometric (complete combustion with no excess oxygen) compared to gasoline, so E10 needs a slight increase in fuel flow. Of course the EFI engine adjusts for this with the oxygen sensor, but the carburetor on your mower engine doesn't, so technically it was running a LITTLE leaner on E10 than pure gas. That might make a difference in carbon deposits if you ran them for longer, although probably not noticeable for this short test.

Thanks for the great video report. I’ve used non-ethanol in my lawn mower & generator for several years now. The gas tanks have no rust or rust developing. Plus carb stays cleaner than before. Your videos are always well planned and unbiased. Your attention to details without using too many words is awesome. Thx again.

I maybe repeat myself but here it comes again: I love what you are doing and making us other better consumer and buyer when it comes to almost everything we have an issue with! We who isnt working in the business and/or are educated in "engineer" stuff! I am a computer guy and me and my friends appreciate this so much! :D

This guy is excellent!!! Been a subscriber for 2 years now. * My 25y/o Tecumseh 8hp Sno-king snowblower runs great. Carb is clean as a whistle inside. * I did have to replace the Carb however in year 20. Engine was surging noticeably. Why? After 20 years of vibration, the throttle-shaft had worn a slightly oblong shape into the carb body!! * That enabled extra air to be sucked in, causing the surging. * The carbs' internals were SPOTLESS however. * WHY?? Because I NEVER used E-blended gas. * The ONLY fuel my small-engines see is Top-Tier NO-Ethanol Premium from Shell or Holiday stations. * I also add a little Seafoam EVERY time, both to the gas, AND engine oil.

Excellent video! Meticulous and well thought out and executed testing techniques! Thanks so much!

I hope you include aluminum and zinc coated aluminum in the test as that is the source of that white solid crusty aluminum oxide that forms when ethanol sits in the bowl. Also would be a great time to do a fuel storage stabilizer comparison!

I liked the water tests! Ethanol fuel doesn't have as long of a shelf life as it comes from the pump. Some older or cheaply made equipment will not have fuel lines or other components that can hold up to ethanol.

I had always heard that ethanol burned too hot for small engines. I see that isn't necessarily the case now. Thanks for all the work you put into these experiments, I've learned a lot!

Thanks again. As an Amsoil Dealer this video is very educational and I'll be sharing it. I and my Brothers personally have a motor on our boat and many years ago before we started using Amsoil to deal with this issue, we had to have the carburetor rebuilt and cleaned out twice due to ethanol. Not a problem anymore of course.

I'm always impressed when I watch a Project Farm video. So consistent, methodical, and concise! It's impossible not to appreciate this level of effort.

Love the vibrations changing to swaying motions because of the fps on the camera, it's cool.

Been watching your videos for a while now. They are always informative and very well presented... Subbed. 😄 from Australia

You're the best, Project Farm. Please don't ever change how you do your videos. They are the only product comparison videos I trust.

It's better for older vehicles - the Ethanol deteriorates rubber hoses and can clog carburetors and fuel filters more easily than straight gasoline can.

PF: "Hey what are you doing?" Criminal: "Putting sugar in your gas tank as a prank..please dont shoot." PF: "How much you putting in..hold on let me get my notepad."

I always enjoy your videos. You are extremely thorough and I appreciate it. Thank you

Good comparison here but one thing i think worth mentioning that takes place in your car and not in these engines is that ethanol blends have a different stoichmetric ratio. Modern cars will use the feed back from the closed loop system to account for the different stoich ratio or in the case of a flex fuel vehicle measure the amount of ethanol in the fuel and then adjust the fuel compensation to account for the correct afr. If you adjust the jet size on your mowers you could run a E85 setup. You will just have to increase the jet size by 30 percent. Awesome channel! Big fan

l like the idea of long term test and to see how the metals hold up on the carbs and tanks, thanks for making these videos, on a side note ive been using cam 2 racing fuel to see if there is a difference with that stuff, so far small engines have been doing well with that sitting in them.

Excellent comparison, I'm a fairly new subscriber and this type of work is very interesting to me. I've been binge watching a good deal of your content on these cold winter days. All have been a great learning experience, especially the tool tests, being I'm a retired substation electrician/mechanic. Keep up the good work! It is much appreciated:)

Love how honest you are, man. True blue indeed. Thanks for years of great content!

As always great reviews! And Merry Christmas to you!!!

When I was in the small engine repair industry we used to have off seasons when no product would come in. Typically around the fall season, but when ethanol fuel started to become common we had constant business all with no start issues. At first we saw thousands of issues with water in the fuel with heavily corroded carburetors and fuel tanks (if the tanks were made of metal). I must have throw away hundreds of thousands of carburetors over the years that were too damaged to be fixed! Methanol fuel by comparison was basically half. Methanol wasn't much better then ethanol based fuel but atleast Methanol had a longer storage life without the use of fuel stabilizers. As time went on and especially when Tecumseh left the small engine industry (which was a very stupid move since it opened the flood gates for all the chinese junk to take over) we saw a HUGE increase in carb issues from sticking needles to leaking fuel bowls. replacing the carb just made the engine run for a few months more if the owner didn't use a fuel a stabilizer or fog the carb. As time went on I decided to leave the OPE repair business because I saw how cheaply made everything was becoming. They're basically making OPE products into throw away items these days. Even name brand stuff is becoming junk.

Another excellent video I enjoyed watching from your channel! I appreciate all the effort and time you put into these vids and sharing them!

Most of my lawn care equipment have two stroke engines. I was constantly tweaking the carburetor to get the engine to run best using 100% gas. I tried a 10% ethanol blended gasoline and my two stroke engines ran perfectly without having to tweak the fuel/air mixture screws all the time. I run my pre-mixed gasoline at 32:1 in everything. I now mix 10% blended ethanol gas at 32:1. My Lawn Boy is 25 years old, so is my Homelite weed trimmer. My Poulan yard blower is over 15 years old. Everything still runs like new.

Love the channel because he actually listens to ideas and gives real world examples the one channel who really gives viewers what they want to see

Subbed. Thank you for doing these hard tests.

You should try storing gas in a sealed container and a normal container and run an engine in a year !

A lot of work goes into these videos! Great info!

Thanks for taking the needed time @ 8:35 It's highly appreciated.

Love this stuff. This is, actually, science in that everything here is testable.

Good job on having quite a controlled test with home garage setup! With something I learn from a engine research lab, there are some point we can improve test accuracy. First is to use a known-volume container for fuel e.g. 50 cc pipet with a stopwatch to precisely measure volumetric fuel consumption, then you can convert to mass flow rate later. As your setup already have watt meters, that's a good setup to have. Then you can calculate specific energy consumption (SEC)(in g/kWh) for each test which gives you more comparable result. Although, this won't be 'brake specific energy consumption' (BSEC) because there is no engine dynamometer. But this method should significantly improve the fairness result with minor modification to existing test setup. Will wait for the follow up test video!

You do things just the way I like, thanks for sharing such excellent, practical research.

Love it... I was waiting for a video like this. Since I make my own non-ethanol, There is an absolute difference when it comes to ethanol-based gas sitting stagnant in a carburetor. My king quad is proof. If I use regular gas, I have to rip the carburetor part after it sits for a minimum of one month because the needle valve, that's made from cheap ass aluminum, is so corroded that it grows and gets stuck in the valleyway. Never once had I experienced a problem since I've been making non-ethanol. I make sure to add a nice splash of amsoil octane boost to bring my octane back up to 87 plus. One note is to make sure that you let the water and gas mixture sit for at least 2 weeks. The cloudiness will subside but it shows small water molecules still suspended in the solution. It's still runs well in engines if it is still cloudy, but something to consider. Thank you, project farm!

I've purchased three Holley mechanical gas pumps for my 1967 Ford Mustang. They failed and I've got a fourth one ordered. Holley explains to me that they don't warranty any mechanical fuel pump that is used with any ethanol gasoline. That pretty much says it all.

I was very impressed by your finding of a 4% decrease in fuel economy with 10% ethanol fuel. This finding is directly related to the fact that ethanol has a BTU rating of only 77,000 / gal vs a rating of 116,000 BTUs for pure gasoline.

What an excellent and very thorough video thinking of every detail, keep up the Great work!

WOW - thanks for the great idea of using a drill / socket to start the lawn mower. I was just about to scrap a 90's model Snapper 2-cycle 4hp mower because the recoil starter mechanism bit the dust. Replacements are non available, and I was trying to figure out if I could retrofit a newer pull-start / cup combo. Ran into lack of measurements in most ebay auctions, etc., etc.

Just catching this video now, almost 3 years later. I recall reading something from my state (Minnesota) that went heavily into ethanol right away (helped raise the price of corn), about your car fillups. Every third trip to the gas station, you are supposed to use non-ethanol fuel to clear out the gumminess caused by the ethanol in the lower octane grades. I didn't think about this before, but no wonder I've had a lot of trouble with my small gas engine snow blower the past few years.

"...it's gonna take 6 to 9 months for the testing to be completed, so it's gonna be awhile before that video is done..." Commitment of time and resources. Planning for videos way in the future. Dedication to independent testing. That's some damn sexy Project Farm pillow talk ; )

Hi, interesting podcast. I would like to see the difference in fuel efficiency for an engine that can advance spark until a knock sensor input to stop detention? Also maybe the effect of an oil cooler allowing the spark to be advanced more without detention?

I helped an older Mechanical Engineering student, a Professional in his early 30s win a DOE contract for small entities develop alt fuels. First of all, in the late 70s, Ethanol had significantly less Btu/ gal than gasoline. We used a Bosch fuel Injector to inject the fuel, fuel/ethanol, fuel/water, fuel/ethanol/water. We injected measured amounts from Graduated Cylinders modified to be be filled from the top , exit the bottom, controlled volume, rpm, time and road grade all taken into consideration. We built the Electronic Fuel Injection System Controllers, which we hooked up to an Oscilloscope and matched our fuel injection based on the calculation of RPM and Injector flow rate controlled by the throttle linkage. My friend was 31, I was 19. 1978. We preceeded the modern mixtures. We ran a 4 cylinder Ford Pinto and a 6 cylinder Chevy Monza. Much learned, good time had by all. I should add that when converted to Btu, there was no difference in the amount of Energy to go a given distance. Gasoline was 114,000 Btu per Gallon, Ethanol / water, Gasoline, Methanol / water, Gasoline ran less and, thankfully, everything followed the Laws of Thermodynamics. It takes y amount of energy to a move a mass x distance. The best one could ever hope for is to break even... the First Law of Thermodynamics.... the Second Law is, you will never break even.

I'm astonished how well put together and detailed this is. Keep up the good work and I would like to see a longer term review with identical machines running the different fuels. Well done.

I have an old farm truck and my four wheeler, and that is all I use in them since I go a long time without using them. I see that Murphy's at Walmart now carries Non -Ethanol gas so it is a lot easier to find than is used to be. Enjoy your channel!

A couple years back, all my generators, mowers and anything with a carb was running like crap after the winter storage. Someone recommended I run eth free gas, never had issues since. I swear by it, has resolved SO MANY small engine carb issues.

Another good one! Thanks for the information!

Loved how you conducted this test and the transparency of your methods - very well done!

I love how thorough your testing method is. Great videos man.

Best channel on youtube. Thanks for taking the time to test anything interesting and giving us hours of quality content that we can show our kids and help them learn.

Enjoyed the video, great blend of knowledge without an overdose of commentary or the look at me time keep them coming….

The pool pump motor repair guy approved ! I use N-E gas in my 90hp boat and lawn motors! ! that was good info thanks farm man.

I just got back from a 540 mile round trip. On the way to my 270 mile destination I used gas with ethanol and got 16.4 mpg. On the way home I used non-ethanol gas and got 19.5 mpg. The weather was the same, the payload was the same, traffic conditions were the same, and my air-conditioning settings were the same. Cruise control was set at 78mph on both trips. I was in Florida so elevation was the same in both directions. My temperature gauge was the same for both fuels. It kind of surprised me how much more efficient pure gasoline is.

Peter Smith. Hi I live in Australia and I own A BMW 320i its ten years old. I used to use 95 unleaded fuel but as the price of fuel kept rising I thought I would try the ethanol blend, after a year my engine light come on but I couldn't get to a service agent, the car was still working ok. So I changed back to the 95 unleaded fuel and after only two tanks of fuel the engine light was off and the car was running perfectly. I will never use ethanol again, and thanks for your in depth reviews it has confirmed what I suspected.

Many thanks for this. I can still buy non ethanol fuel and so always do for my 60s air cooled VWs. I really appreciate your uploads. Thanks.

Note that the labels on the gas pumps say, "UP to 10% ethanol." I tried that water test on some regular gas at the corner market and it was 5%.

Just found your page and want to say THANK YOU.You have some amazing videos. You are obviously a very smart man.Thank you for sharing your knowledge.

you have some of the best testing i have seen anywhere.......

Fantastic inguinity in all tests. Great channel!

Outstanding information as always. I always look forward to what ypu are doing next. Many have come to appreciate your work!! Thank you

Good info on removing the ethanol. Thank you.

Really appreciate the honest test. I'd like a much longer test on a car or truck. Also look into the "green diesel" as well. What is the heat content.

Great test thank you for showing us.

Non-ethanol gas is best for small engines. For cars that are driven often, there is little monetary advantage. I don't have anything against ethanol since it helps me acquire good equipment to repair. Finally, fuel injection has become economically viable for the economies of scale. This generator must've caught your eye!

I had to have my Billy Goat leaf blower repaired 3 times at a total cost of $600.00+. (Paid $750.00 New) One of the Cub Cadet Dealer shop guys felt my pain and informed me about non-ethanol / REC gasoline. All I can say is everything now is running on REC gas with no more problems. I have a Cub Cadet string trimmer & Backpack blower that is 19 years old. Ever since I started putting REC gasoline in my lawn equipment and my two Stihl chainsaws they just purrrrrrr idle without stalling and start on the first pull. Plus I can leave the gas in them from one season to the next without any worries. I even run the gas in my 23 HP Commercial Cub Cadet 54" Tank Zero degree mower, W/ 5 Gal dual tanks. My neighbor has a 25 HP 60" Cub Cadet Tank which broke down. When he borrowed mine he could not believe the power it had and how much faster mine was compared to his larger sized engine. Now I only use REC gas in small engines that require just gas or oil mixed fuel, I put regular unleaded gas in my cars. My proof in in the wallet. For three years I have not needed to have ANY of my equipment serviced. I use to drive 1 hour round trip just to fill one of my rotated 6 Gallon jugs. Last year a Marathon station was built just 10 minutes away from where I live which sells REC gasoline, now how lucky it that?

Thank you for the upload. Like the demos that you do. Keep them coming. Ethanol gums up when it sits in the carb.

Terrific work. We appreciate your payowla free conclusions and testing.

I always appreciate Project Farm's objectivity. Thanks for taking the time to do the testing.

Mechanical engineer, primarily aerospace and engines. Great job on your evaluations - now a subscriber! Someday I'm gonna binge on all your videos to see what I have missed. We'll done.

I'm a little late watching this video, but thank you for comparing gasolines. It is surprising how much carbon buildup occurs in that amount of time.

Very informative information. I was told to run non ethanol in a small engine. For reasons. We did get a new Sheetz convenience store in My area & they do carry non Ethanol fuel ⛽️!
