Pretty much every two stroke oil out there being made is now "D" rated and not long ago was "C" rated which by the way was decent oil until these "strato saw's" came along, then everyone had to up their oil game and go to a better grade of oil hence "FD" to give a little more protection. So for Stihl to be messing around with older sub grade rated oils which were all the rage more than 20+ years ago lead's me to believe it's no accident or that they are unaware of what's going on. Yes I know they don't bottle oil themselves but by their direction to who does for them, they are not that ignorant it's a decision they've made on purpose. That decision is have early or premature wear or failure so they can sell more new product plain and simple. The Stihl fan's can say oh no no they would never do that, when corporate greed take's over we all know where that lead's. You probably don't want to touch that one but I have no problem saying it all point's in that direction it seems; anyways I've rambled to long take care.

I had a MS251 Stihl given to me because the compression was so extreme at cold start that the owner didn't want it anymore. I tried it and he was right, I couldn't believe how hard it was to start it, I'm not joking. I pulled the muffler to have a look inside and just like you, could see carbon and a dark honey colored piston. I did notice that once the saw had warmed up it would start like normal and ran perfect but once it sat overnight it would go back to extreme compression again. I did my research and noticed other people dissing Stihl oil and how much it coated the piston and cylinder so I called the person who gave it to me and low and behold he was using Stihl oil mix since he bought it. I then read about Echo's Red Armor and how it cleans so I bought a gallon of True Fuel (straight gas) and mixed Red Armor into it to achieve a 40:1 mix and ran that saw through a bunch of firewood until the gallon was done and it solved the issue. Now when I pull the muffler there is only a light coating of carbon and the piston is silvery like it should be. Now I have a nice running Stihl.

You never cease to make me laugh 😂 “it should burn it off… *smirks* … it’s not!!”

Amsoil saber and 91 ethanol free for 5 years at 50:1 and no trouble at all. Mufflers are clean Saws start and run perfect every time

Richard Red armor been working good in my 500i and 661 40:1

Pond water saw!! Nice job Richard!!

love your content! Iam learning quite a bit thank you

Absolutely switched oils to a FD rated oil after the same issues on a ms192t and a ms200t. Haven't the coking issues since. 👍

I'm new. Love the knowledge you're putting on people.

🍻 Cheers buddy! As I've said before, I bought my 261 new and only used Ultra. My saw doesn't have any of what you showed. It must be your gas! 🤣 Stay safe my friend!

Love watching the channel

Muffler on our heavily used FS94R is the opposite. Splooge dripping from the muffler but port and piston are shiny clean. Saber ftw!

Been running red armor since I found your channel, run them like I stole them

I have noticed that most all Mtronic/Autotune saws have that blow by coking on the skirts. Maybe due to the fine tuning by the saw itself. I have run Red Armor at 36:1 since I've had my 261cm, it still has that brownish on the skirts. Saw runs strong and all, but just reporting my observations. BUT there is very little carbon buildup in the exhaust port. So that is a plus. Saw is ported... Love these videos Rich. Thanks for doing these for us. 🍻

I just picked up a used MS241C that looks the same way. It is M-Tronic engine management. The guy ran the same swamp water.

After a lot of research im covinced the ultra is designed to keep the carbon inside the saw and not release it to the atmosphere, all to keep our environmentaly friendly buddies happy. Great videos Richard for telling and showing us your work and evidence of how crap that pond water really is.

I have been running SuperTech in that easy measure container for years. I haven’t had any issues, I run all my saws, blower and string trimmers on the rich side. They all need a load, run them dull or with no string p, they blow up.

Rich nice video and great info.

Great video! Just subbed! Now I have to check my equipment as I’ve always used Ultra!

I have quit using stihl ultra HP oil in my equipment. I now run amsoil saber at a 40:1 mix and I use ethanol free fuel. I also have recommended that my friends and family switch to amsoil saber as I have . Stihl needs to get the oil up to the fd standard. I might consider running it again if they do, but amsoil is a good oil.

I have used sea foam in every two cycle I have owned, plus chevron Techron. There is very little carbon on piston, muffler. This starts the first use of the equipment, including out board two cycle. I put a 40/1 mix of oil.

Thank you Richard for telling folks the truth on this issue. I really hope that folks take the time, only a couple minutes, to write an email to Stihl expressing their disgust that in the US we do not have access to a Stihl FD rated 2 stroke oil. Keep on making these videos Richard. You are one of the only people out there staying on this issue. God bless......yee-haaa!

I run a little seafoam in all my 2t a couple times a year. I also don't use stihl oil. Bel-ray or motul.

Thanks for doing these videos

Hey Richard, youtube canceled me. I just re-subscribed. First video I've seen in a while and you start out with my pond water! 😅😂. Cheers buddy! 🍺

I run castro 2 cycle oil...have for many years..i have saws that are 50 years old...3 pull cold start

I used to work on a lot of outboard motors . Many customers used seafoam in the motors on a regular basis, and the pistons and exhaust ports definately had less carbon than those that didn't use it. To clean up a carboned up motor requires quite a few tanks of fuel to get any real results. This stuff doesn't work in short term use.

I think it would have helped if you had ran the saw hard cutting for a tank after loosening up the carbon with the shock treatment

Hey Richard, like your videos man very educational I like the way you break it down. In your humble opinion. Which I value. Which oil would you run in your saw.

Haven't tried it in a saw yet but agree, sea foam is good stuff for loosening carbon. Also agree on why try improving a sub-par oil with additives when there are so many far superior oils on the market? And many of which are also cheaper!

Takes awhile for the seafoam to work. I've cleaned up saws with it before. I usually stall them on it and wait a day or two to re start. I'm with you. Use an oil that keeps it clean. If you can get the guy to switch to Red Armor, that saw will be clean in no time. I use Mobil One synthetic high mileage in my stuff. My stuff stays clean and well lubricated. I have been thinking about changing to Red Armor though. Just to change things up a bit. The only drawback is price. I get four applications out of one quart of oil. Saves money.

Been running red armor ever since learning about Stihl pond water from this channel, THANK YOU!! Just picked up an ms462cm and wondering if i should go 40:1. What would you recommend? I usually run my saws like I stole them 😮

Plenty of people treat seafoam like its a wonder additive because of the smoke. Reality is it will take time to clean out large build ups. If you add a little bit with each mixed tank of gas you will prevent build. Preventative maintenance is always better then reactive.

My exhaust port is clean as a whistle, but just the ever so slightest damp with oil. Is that good or bad?

A lot of folks let their gas cans get hot out in sun, so gas turns to vapor and gas mix gets oil rich. Best to mix small batches for use in a day or so. Keep gas cans in shaded or cool area.

I plan on running amsoil Saber when I use up my ultra, due to your advice. Problem is I have 2 gallons of ultra and I hate to waste money. Do you run 50:1 with amsoil? I have seen so many different mixes on forums out there.

I picked up my first "real" saw a couple weeks ago. a 261. I trusted that their ultra and 50:1 was the proper way to do things, and I'm a stickler for doing things right, but the more I look into it, I guess their oil is garbage? I've ran a gallon and a half of fuel with it so far. Guess from now on I'll use amsoil saber at 40:1 like I keep seeing people mention?

what do think is good oil,?

Great video went you got a stihl you got to have sugar in your pocket buddy . 😊

Seafoam might be ok to clean up the combustion chamber but its going to take a long time for it to do anything with the exhaust port. Better to run an FD oil like Red Armor which will eventually clean up the worst of the carbon buildup.

Ot supposed to be run real hot . Reckon gotta do it a lot

I have a question? I respect your opinion alot, so this is why I'm asking. I was bought a Chinese backpack blower as a gift to see if I'd like the backpack blower or hand held blower any way it's an EB650 It's a surprisingly damn good blower I've had it for over a year now with 0 issues, I do however take very good care of my equipment. Any who... It calls for a 25:1 mix which I've been running. What oil in your opinion is the best to use? Do you think Amsoil? And what ratio should I mix if I use said oil? Thank you in advance Richard.

That sea foam is good stuff. But I think it takes regular use to do what it does best.

Bagus

is this stuff similar to the subaru upper engine cleaner?

I'm from Australia. Our HP ultra is German made. I've never had cokeing on the pistons and the cranks are wet at 40:1 with 95 octane

Two stroke engined don’t like to idle, they do much better at full power! I haven’t ever had a problem with Ultra.

😂 Richard, you're working on a 261 and I was the 261st person to like this video 😂 I was wondering what your thoughts on Stihl HP Super are?

Our stihl ultra hp is FD rated in New Zealand. FYI

Once it's already a lot of goo seafoam dont really do to much. You need to use it as a preventative kinda.

Jeden z tych 20% 😎

If it was a 50s outboard motor, Seafoam might do something. That's what is was made for. There are products for removing carbon. Wire brush, since there's no magic.

Run 3.5 oz of Amsoil Sabre and 2.6 oz of Red Armor in 2.35 gallons of ethanol free fuel that will clean it up

If they improve the oil you'll never need a new saw...i think its as easy as that...

@6:00, the saw finally smokes good! (Joke.)

My grandpa uses the same oil an has the problem

Hey Richard Flagg

So How Many Actual Failures Have You Seen From Stihl Ultra Cause I Can Live With a Little residue on The Piston If There is No Evidence of Engine Failures I’m Not a Believer in This Analysis or Theory

Sea foam is awsome old school product. Stihl ultra is new school garbage. Thanks for my dose of smiles for the day.

PLEEEEEASE tell me you just seen this in a recent KZfaq short.

Soaking with gas will remove carbon. Gotta soak overnight.

I am pretty sure there's something with stihl hp ultra în US. Here în Europe these problems with hp ultra they simply dont exist, I cant explain why, but stihl is doing you dirty în US

I'll tell you why they don't improve their oil... they want you to buy more stihl stuff!

It had to do something to smoke that much!

If you want to clean a 2 stroke engine or keep it clean, run Yamalube Ring Free Plus Fuel Additive from Yamaha. It doesn't get any better than this...period!

Amsoil is the best you can get

I gotta say this. I don’t know why, but a lot of people who love to use seafoam (I like it, I use it On Occasion) seem to be baptized in the thought that SMOKE coming out of the exhaust means that you are actively cleaning something inside the combustion chamber or valves or something. Fact: put a few drops of Oil or Transmission Fluid in the carb of Any engine, a BRAND New engine (what is there to “clean”) and you are going to see THE SAME DARN SMOKE!!! Smoke does not mean “cleaning.” Give me a good response and I’ll subscribe And like… Promise.

I just bought some Seafoam this morning... Weird.

People are truly lost and ungodly

Techron or Yamaha Ring Free works better than Seafoam, just saying.

Cleaning pistons rxp no shit use sparingly

Stihl doubles your warranty when you buy ultra with your new saw because they know you will need the extra coverage when running pond water.

Why epuldnt they hit subscribe? That's shady

Sthil ultra is by far a waste of money you might as well run used engine oil than that garbage if will shorten the life of your saw engine in exactly the same fashion as ultra. The best way I have found to clean the carbon out of a customer saw is to get them convinced into running shaffer's XP to cycle mix oil I have even gone as far as to giving them a free quart of it which will make 10 gallons of 40 to 1. So far everyone I have given a free bottle has come back offering to pay for it and they buy more and become a permanent customer. People complain about the price but it's really not that expensive especially when you compare it to some of the OEM oils out there. It also comes in a handy 3 oz bottle as well that is set up to make a gallon.

I never have had a problem with stihl oil, but seafoam is a waste of money.

Complete nonsense.... Doesn't matter at all. Good content for KZfaq mechanics I guess... got my view.

Hey @richardflagg3084 you can lead a horse to water…good tips…sorry you also have so many free riders on your channel, it’s really frustrating that people would prefer to watch your efforts, but pay KZfaq and not the person that does the work…even when it costs them nothing to subscribe…If I could get my regular viewers who haven’t subscribed, to subscribe…I’d be able to make a lot more vids and work on saws as a primary income vs having to do another job too…but I guess KZfaq isn’t going to change it when they get so much for nothing…anyhow have a good weekend buddy…keep doing what you love 😎👍

TALK TOO MUCH.JUST SHOW CAUSE AND EFFECT .
