When I had two stroke gear I used to by TCW3 by the gallon at Walmart. Toward the end I used Pennzoil synthetic. While I have used SAE 30 in a pinch, it is clear the two stroke oil is a different product. Much different smell etc. It's not expensive, why not use what's recommended for the job?

You can even use it in a 4 stroke 2 stroke Stihl......you know...the 4mix.

It's more likely to see it listed as a ratio such as 50:1. Good move buying Stihl, it is great oil and a great product. Mix as directed, shake, use. Try to mix as little as needed. I do store and use 2 stroke mix with no problems but fresh is best. The Stihl dealer I worked for hung a note on each repaired item saying use fuel no more than 45 days old. A little extreme but so many fuel issues with small engines. 2 stroke equipment will store with less problems because the diaphragm fuel pump type carbs do not have "bowl" that is open to the atmosphere like 4 stroke equipment.

OOOPS The correct quantity is 2.6 oz. per gallon. I have used straight 30W for chain lube on my chain saws. The Stihl oil is synthetic and is thinner than the 2 cycle oil I have used in the past. Wizard made a good point that I had not thought of. Outboard 2 cycle oil, IIRC. was a thinner oil. Also I have read that the outboard oil should be low ash less for cleaner burning.

I have also read that CJ-4 oil is low ash.

Stihl 2 cycle oil is good quality. Check your mix ratio, typical mix ratio 50:1 is 2.6 oz per gallon of gas.

FWIW, I used to mix 2 cycle oil by the 55 gallon barrel. Everything ran on a 50:1 ratio. We had 10 string trimmers, 6 flo-jet mowers, a few chain saws, and 6 back-pack blowers of various makes. With 2 cycle, it is more about the quality of the oil than the weight or even the ratio. Here, at the house, everything runs on Stihl 2 cycle at a 50:1 ratio, using E-10 from the pump.

X2

I had two stroke Honda mopeds, and other two stroke bikes
I always used two stroke 'Injector Oil' synthetic rate TCW-3
It burns clean less smoke, less carbon, no clogging the carb or the exhaust
You can't get good results if you try mixing regular oil instead of the right stuff

ASHLESS aircraft engine oil but it isn't inexpensive.

I've always used 30w non HD oil. Never had a problem in 40 years.

Ya know charley, I hav enever thought of that. hmmn? but if it extends the warrentee , it's sthill a good deal;=) . I have always used a suggested " mix" oil for my small engines. and had sthil chain saws, weed eaters and never had a problem.

One guy I knew said, just used good car oil at such and such mix.. well the story was his stuf didn't last as long.
Get the good stuf and mix it as prescribed. and if you can, get NON ethenol gas.It may be recomended to.
Good cuttin.
