4oz Ryan 2 cycle oil to 1 gallon gasoline. If you use two cycle oil other than Ryan 2 cycle oil, mix 6 oz of oil to 1 gallon gasoline.

I agree with George's answer. I have a Ryan 263 and the manual says 4oz of Ryan oil to 1 Gal. And 6 oz of other oil to 1 gal. I've only used it with unleaded gas.

Ryan special 2cycle oil 4 oz per gal gas. Other 2 cycle 6 oz per gal. This is from a very old label on a Ryan. Leaded gasoline was in common use at that time. Label does not specify gasoline type. Hope this helps.

keep looking on google. i don't know, but someone posted the ratio of 32:1...i was using 50:1 in mine, but i'm adding oil to the mix in the future!
