AVGAS

3 posts in this topic

Yes, you can use Avgas for thumps. I suggest mixing it say about 20% Avgas and the rest pump. This is a good mix especially in the winter when most gas is oxygenated. Not as good as race gas, but next best thing.

Can you use AV-GAS in a 4-stroke. All I can find at the pump is 91 octane gas. The manual recommends 95 octane.

Check your manual again. There are three octane rating ssytems: RON (research octane number), MON (Motor octane number), and (R+M)/2, (the average of the other two). What you read on the pump is (R+M)/2, due to a bad decision by our congress. The manual specs one of the other numbers. 91 octane pump gas is what I use, just make sure there is no ethanol in it.
