Looks like you really went above and beyond the call of duty to procure your test beakers. Research like that shows us how dedicated you are to the craft; thanks for taking five, I mean one for the team.

As far as ratios of water to gas and using the recommended ratio of additive to gas, this is the best one I've seen. Thanks for doing it the way you did.

This was just what I needed to find out. I stopped by a gas station to top off my tank and 3 miles down the road the engine stopped and would not crank back up. Just ordered some STP water removal to get myself back on the road after AAA brought me back home. Thank you Steve!

I bought some STP gas treatment for some bad kerosene in my heater. Added a few drops to the tank this evening. Will add more fresh kerosene tomorrow and try lighting it. Thank you for sharing this video.

Thank you for taking the time to make this video. My gas hose was left exposed to a 5" + rainstorm. I forgot to drain it prior to fueling my riding mower. After siphoning 2 gallons of gas with 2 inches of water, I poured 2 bottles of HEAT in and used a syringe to inject HEAT into the carburetor bowl. Started up ran rough for 30 seconds or so, then took off and ran as normal. I used HEAT because, as you stated, "must say removes water". It does and it did.. Again, Thank you.

You just saved me a $200 trip to the shop! Blessings on you!

Nice job Steve , but I would be very interested in seeing all of the beakers after an hour ! :-)

Thanks for the tip on water removing products. I was using ethanol blended gas and let it set for a month. When I finally fired it up it wouldn,t hardly run. I have putting up with my bad running engine for a couple of weeks and today I put in some STP gas treatment, and am using ethanol free gas. Engine runs fine today, knock on wood. Thanks again for the test run on water removing products.

I started using the stp on my motorcycles because we have very high humidity and I could see vapor coming out of the exhaust after a few days of not running. I put it on every other tank, and I noticed that there is almost no vapor now. I also use stp carb cleaning additive, and the iddle is smoother.

Steve my dad died 10 years ago I have learned more from you tube and videos like yours to maintain and take care of lawnmowers and chainsaws than I had learned from dad. Keep up the good work Steve much appreciated!

Good video , we should do it again with more water in the fuel until it is not absorbed to see what is best at this .

I had a problem with a surging motor and I found one of your videos last week. I am very impressed with your work. Excellent advice with a little humor. I will be going back through your older videos and watching plus any others you make. Thank you. Great job.

Thank You Steve ... one of the most concise demonstration/tests I have ever seen on KZfaq. Very informative. No extra babble or guesswork. Nicely done ! !

That was a great show Steve you’re the man keep up the good work I watch your show every time it comes out.

Extremely interesting and useful experiment, Steve. I do have a few thought to share. First, the water was already in the fuel BEFORE putting in any of the additives. If I personally encounter fuel that has water already in it and it is for a small engine, I don't bother trying to make that fuel useful again. I dump it and get fresh fuel. I don't see that it is practical to put additives into a gallon of small engine fuel in order to get rid of water that is discovered to be in the gas. Second, the way people want to use any of these additives is to mix the additive into the supply of small engine fuel at the time the fuel obtained, with the additive then being expected to PREVENT water from ever forming in the fuel. Stopping water from forming in fuel is an entirely different situation than removing water that is already present in fuel, at least in my mind it is. Unfortunately, nothing about this experiment demonstrates that putting any of these additives into a fresh batch of fuel will prevent water from building up from condensation or other causes over an extended period of time. I store my small engine fuel outdoors in one gallon plastic cans. The temperature changes, rain, and other conditions can allow small amounts of water to form or get into the gas over time. Thus what I want to know is how effective these additives would be over a two to four week period of time in keeping fuel free of water that forms on a repeating basis. We don't know if there might be a saturation point reached where these additives would then fail to prevent further water from forming in the gas. Perhaps you could do an experiment where the additives were mixed with pure fuel at the start than a small amount of water was added to each fuel container every day or two for a period of 30 days. It would be much more useful to know if any of these additives would still keep the fuel free of water at the end of a month. For those of us don't do a lot of mowing, a gallon of fuel might last 30 days and we don't want water in it at the end of that time. What I learned from this experiment in your video was still highly useful because if I fill my vehicle up with a full tank of gas and discover there is a little water in the gas that I purchased, I can easily get the water out using one of these additives and don't have to drain the tank or lose the fuel. I was very impressed with all these additives. Great video. Thanks for sharing.

Hey Steve. We have a tree service in south central texas and and wanna give a big thanks to you for all of your wisdom. Youve been a big help.

I was impressed that the STP did the job with the least amount. Great video.

Methyl hydrate has always been our go too in fuel tanks on vehicles and such. The only other thing we have done is freezing the water and dumping the fuel in another container works with outboard motor tanks and Geary cans pretty well. Keep on keeping on

But Steve you R on point. I just fell into your words. For someone never fried an egg, never worked a stove. You go through steps in sequence to cook the egg. My dad would explain how things to be done. Right way😉. Q: When E & I realized water was in mower tank, would not start. Did this do anything to my sparkplug. New gas now, but still not starting.signed "Need my grass cut," Help A.Smith

I have to say this, Steve... this video (and all your other content) is ABSOLUTELY “top notch, bud! You are clear, concise and easy to follow. The information, you provide, is stellar! Thanks so much for making your videos! Something I’d like you to do, would be a video talking about gas stabilizers. Are they necessary? If so, what’s the best one? You know? From one proud Canuck to another: Just brilliant content, bud!

Thanks for doing an accurate, real life test! All the other guys take a quart of gas, add a cup of water, then 2 cups of treatment, and guess what, nothing happens. If you average a cup per quart? you would have a 1/4 tank of water in your vehicle, and no treatment is going to fix that. Your test shows how the treatment works on normal condensation in the tank.

Good comparison Steve. I bought my first car in 1970 and methyl-hydrate is still my go to product for gas line antifreeze. It's inexpensive and it works.

Just discovered your videos today after doing a tune-up on my Honda mower and then experiencing surging. Amazon will have those micro drill bits delivered here shortly. Also, have a Toro mower where my sister is pretty sure she put bad gas in it -- now it won't start. Enjoyed watching your experiment. Thanks again for the great videos - good pace, easy watch.

Best test I've seen yet Steve, very well done. In another vid it was shown that Sea Foam wasn't as effective but apparently it has high "lubricity" and preservation qualities to prevent breakdown of fuel over time.

Wasn't about the money saving..... saved me the time and issue of trying to find a replacement for methyl hydrate ... if not available. Thanks so much.

Actually going through this as I type. BEST video on the subject. Us girls wanna SEE that it works and to know WHY its broken. Thank you much.... because I was dreading a trip to the shop (to be preyed upon)

Thanks for spending the time to save us from wasting ours! I was a Lil worried you were gonna drink the wrong bottle though!

Great demo! I'm old enough to remember my Dad insisting on us dumping a can of Dry Gas in the tank once the freezing weather set in. Guess it worked.

I thoroughly enjoyed and appreciated your tests especially after going through an arctic blast for 5 days here in North East Tennessee . We experienced lows ranging between 3 degrees on some days to highs of 14 degrees on some . Night time wind chills ranged from 4 degrees below zero to 20 degrees below for the lowest . My 2000 chevy silverado ran fine until the blast hit us and now it will start for a split second and then die . I'm thinking that water in the tank , fuel lines and the fuel injectors has become frozen and is what is causing my problem (?) . I'm going to try the STP product because it looked like it took less product to get the same results as the K-100 and the M.H. . I left the Seafoam out of my preferences because I don't like nor do I trust it . Thanks so much for your time and efforts in doing this experiment - 2 thumbs up .

A very interesting experiment. It would also be good to know, if after a week or so, you added more water into the pretreated test samples to know if the additive will still remove water.

Methanol (methyl hydrate) is a colourless liquid with an alcohol-like odour. It is one of the basic chemicals of the organic chemical industry. ... Methanol is completely soluble in alcohol, water and ether. Methanol is generally used for industrial manufacturing purposes and has a variety of different uses.

Thanks Steve. I found water in my tank just from it sitting. The gas I add is always clean. I'll use an additive a couple of times a year now.

Can't speak for the others, but we use K-100 in all our engines 2 stroke, 4 stroke, marine and land craft. All small engines we also use non ethanol gas.

Great video, Steve...!!! The information is PERFECT..! The comedy is just as good (as always) - Canadian Scientifically Approved Beakers - HAHAHA...!! Excellent..! Love how you swig outta the GREEN one (water) at the end..! But, all kidding aside, the information that you shared, and the way that you did so, is AWESOME.! I am SO glad that I subscribed to your channel. I have shared YOU with several people - I hope you are getting MANY, MANY new subscribers - You are doing a wonderful service, and doing it in such a GREAT way (in my opinion)..! Looking forward to the next one... Keep up the good work..!

I think they just do the opposite action of ethanol removal, like you showed us in another video of yours. Of course they don' t make the water disappear, but just mixing it with the rest of the fuel and forcing it to pass thru the exhaust system, thus getting the tank rid of it.

Thanks. I’m on a trip and stuck with a bike not running. I checked KZfaq and found your video. Perfect! Maybe I can walk to a place where I can buy this. Now I know what to look for!

I am one of those old school guys. I buy Methyl Hydrate by the 4 litre (1 gallon) jug. I use it for a lot of other things. Interesting experiment Steve.

I think MH is similar to what I remember as a younger person as Dry Gas. I remember we always added it in the winter when filling up our car tanks.

Thanks Steve, this is the best test I have watched so far, watched other similar tests in which both sta-bil and star-tron failed.

I believe most thought these products were a scam. Great job. Great instructional. Whoa! How many beers did this take?

This video made me subscribe. Should have did a burn test also!

very good and informative. Im going with the methal hydrate

the engine science we all missed

Green water tastes good better than beer.thanks for the videos also watched piston scoring, helps to know the cause

Very informative. I am a more informed consumer, which saves me money, because of your channel. Thank you Steve.

world class video. so detailed and so exact. I appreciate all of your videos of what you do. you're the best... Bob...PS: please don't drink out of the wrong bottle.

Checked out your video because I believe that moisture is the culprit of why my mower won't crank. Nevertheless, I found it to be very informative and more than likely not a big risk. I will be heading out to an auto parts to pick up whatever is available. Thanks for your advice.

Wow that was great thank you I don’t know why I’ve never thought of trying to use a treatment before to get the water out of my lawnmowers gas. Awesome awesome thank you!

You can also go the other way , add water to E10 ( in a suitable container ) and shake which will bind the alcohol , decant the gasoline off to use in your chainsaw etc. Once the alcohol is removed the gas will have a slightly lower octane however . If you live in an area where straight gas is hard to get , this can be useful for small quantities of fuel on engines that were not designed to run E10 .

Thanks Steve, very informative. I’ve been using the STP product and I’m happy to see you’ve proved that it works.

Firm believer in seafoam. It’s more than just water control. It works very well as the stabilizer as well. And keeps your carburetters clean too.(or at least better than having not put it in.) i use it in everything from my chainsaw to my snowmobiles to my truck.

Thank you for an excellent educational video. The comparisons of all the manufacturers additives saved me a lot of "trial and error" work. Carry On Sir!

By any chance have you been watching project farm videos he did this testing as well.

Love your show bro never knew off hand your on the island … then once I found out wow right on!! Anyway I have a few cards up my sleeve and would love to meet up one day and share few with ya… anyway keep up the great show you’ve taught me me a lot for sure .. take care and cheers!!

I've been rebuilding carbs all week on my power saws.All because of ETHANOL.Thanks for the video,it was my goto education.

WOW! I loved the test - loved your honest surprise about each products claims and results. Definitely subscribing. 😀

Steve, I have often wondered about these additives. I have used Seafoam in my Kubota L3830 diesel tractor for 12 years and have never had a water in fuel issue. Either I am very lucky or it works. I Use according to Mfr suggestions for ratios. Thanks for a great and informative video, as always. Michael O. Alabama USA

Great video, $2.00 MH seems the cheapest success, but they all work. Enjoy all your videos good information, thanks

I'm an Old School Type, & Didn't think any would work for me Steve, I would have been Stripping Down the Carb & Tank Great Test & Vid, Cheers Steve

Thanks for the informative video, however, would have been instructive to see if this would work on a gas tank with some water in it and then see if it would start up. This is the quandry I have now, putting the chemicals into the tank in hopes I won't have to pull the unit apart and drain it.

I love this video, I just learned something.. anything for diesel engines?

I am watching this video today because I fired up all my small engines for the season. I tried starting my generator and it would only run when I shot in a little carb cleaner. Started by draining the carb and had an orange sludge. Decided to drain the tank and it had quite a bit of sludge so now I'm gonna change the filters and put in fresh gas along with cleaning the carb.

Thanks for that! It's such a big issue in Cali.

Wow!! I had no idea the products would work so well. Thanks for the great content Steve.

Steve! One of the best videos testing this stuff so far! Great job. Regarding the project Farm video....it was unrealistic!!! donyboy73 has done some K100 videos as well that were good. Anyway love your channel keep it up.

I done exactly as you said, some STP and then give the car a good shake, i must have the percentages wrong

thanks! this is a great video. just wanted to know what works

Great unbiased test. I enjoy your real advice and tip.

I love live experiments. This was both fun and educational. Thanks.

if you look on the sea foam it is also a stabilizer as well and most automotive parts house it is about 9.00 a bottle it works but you have to use the right amount of if

I love seeing you doing science. Really do. Thanks for doing this, steve!

Great video! Would have also liked to see what would happen if you added more water to each bottle, to see how much each batch could handle. Still seemed like the Sea Foam was the least effective for the most money. Great job.

LOL!! I loved how you took a big swig of the laboratory green test water!! Nice touch. That was very impressive. I was very impressed with the STP... same results with such a small amount of the product and not bad on the price. Thank you Steve!!

I have to say, I really didn't think they'd work! Simply amazing.

Great vidio I would like to see this with the junk 87 fuels. Water mixed with ethanol, then add these water removal products.

These products do work with a small amount of water in the fuel, but there is another way to clear water in the float bowl without taking it apart out in the field.. The problem with water in the float bowl aside from the fact it sits at the bottom of the fuel is that it's surface tension stops it from flowing through the small jets into the carby throat, so if you get enough of it what can happen is the engine will idle ok but when you try to rev it the extra fuel flow draws the water up to the main jet blocking the fuel from entering the carby throat, engine revs drop and the water falls back down in the bowl and allows fuel to flow again and the engine rev back up and the cycle repeats. When you add a water dispersing solution like theses ones it breaks the surface tension of the water and allows it to pass through the small jets and go through the engine. But if there is enough vacuum on the carby throat then you can easily draw water up through the main jets but in normal operation you wont get enough vacuum to do that. So the solution is to open the throttle fully and when then engine RPM rises high and or cuts out as the water blocks the jet, place your hand over the carby intake (or thumb on a small engine li chainsaw) keeping it at full throttle, this will increase the vacuum at the carby throat and jet greatly suffice to draw water through the jet to clear it from the bowl. Once the intake is chocked off the engine will stop firing as it is flooding on fuel so before the engine speed drops enough to stall you remove your hand from the carby keeping it still at full throttle allowing air to enter it and the engine will rev back up, as it revs up high you do the same again, repeat this a few times will be enough to pull a large amount of water out of the carby. The same also works for partially blocked jets in particular idle jets so if you have an engine that runs but will not idle then try the same procedure choking it at full revs and throttle and un-choking it before it stall and do that a few times and you may find it is enough to clear the blocked idle jet and it will then idle.

k100 is the best Little pricey but it does the job

Good to know about M.H. and 2cycle.

Wrong beer, Steve, it was green! Great video and awesome results.

I am surprised that any of them worked like they say, but I do have to try some of them out.

Great Illustration!👍🏾

I love watching your videos, hope you never stop making them, so informative and funny.

Awesome test, love the close up shots of the water and after the treatment! A nice treatment after the winter season.

Hi Steve, How are you, one thing i like to say your are so informative, of what type of water remover to use...after all the tests you did..i think i found my preference..the best one according to your video, would be Stp water remover.. Thankyou Steve always informative.. cheers. .....

Great video Steve, but I'm wondering if you can show us, how lets say a lawn mover running with this gas in the tank for each additive that you have used. I would greatly be interested in those results Thanks.

Very helpful. Could you test Heet (red vs yellow bottle) next time? Hate to ask, but does it remove beer from gas, in case someone makes a filling mistake?

Excellent show there man. I've got water issues in my fuel and appreciate your efforts. Been a sub for ages by the way.

Thanks Steve ... I just added 3 - 4 ounces of Seafoam in my 2007 VW Jetta a day ago because of fuel issues and it was -40 Celsius here in Regina, Sk and it worked great ! But I am impressed by all the 4 comparisons and think the other 3 actually out-performed the Seafoam even though the Seafoam does work fine as well !!! :-)

Steve I use K100 in all my equipment and my ATVs and snowmobiles. I like that if you add this to your gas just before the season end it is good for 2 years at the proper dose. Also the other properties of the K100 is raising your octane points and bringing back stale fuel and conditioning your seals and gaskets. I will not use anything other than this product just my opinion

You should let these samples rest and see if the water separates again.

Excellent project. It would be interesting to see if you added more of the water would still remove it as well.

Great video. I use Seafoam in my truck and it works great. Think I may switch to STP. Love your videos.

Now I know to buy the STP - seems to be the Best Bang for the Buck. Thanks for the eye-opener, Steve.

I would have liked to see them after sitting overnight. But a engine running would vibrate enough to mix them up enough.

thanks for a great video Steve . i am amazed as well.

I'll have to run some in my 4 stroke small engines now and then. 👍👍👍👍👍

STP is damn impressive. Awesome work bro!

The water is not removed from the fuel. The chemical that you're adding to each sample does not dissolve water molecules but instead it removes the stickiness of water molecules and lets the water molecules mix with the fuel at a microscopic level. Therefore even after you let it sit for an hour or two, you will not see the water at the bottom of your Beaker because of the small amount. As for adding the food colouring, when removing the stickiness of the water, I also would assume that the food colouring is being separated from the water molecule also which ends up being diluted with in the large amount of fuel. These chemicals reduce the stickiness of water molecules so that they can be passed through the fuel system and evaporated inside the combustion chamber of the engine.

cool video. I had bought and put in the STP before is even this. I think I'll be happy qith the results.
