" Howdy, Randy.

From what I understand, 50:1 is the mix of fuel to oil. 16 oz for 6 gal. I think.

Also, I have read numerous postings on 87, 89, and 91 octane fuel. The most popular answer is to use 87. Something to do with the additives in the higher octane fuels causing problems with the additives in the oil.

I really don't know which one is better, this is just my experience with these type boards and gathering everyone else's opinion.

Good luck!
