1961 Scott 40 hp 50:1 ratio 91 octane so called 100% Gas I have not tried corn gas and probably won't. There is a difference between a 12 gal tank and 50 gal tank hm-mm might might have to re think this one??

Re: What grade fuel are you running?

Any actual advantage to running a higher octane fuel instead of basic 87?

... aaaaaaannnnnnndd they're OFF!

Sorry Tony ... there are about a zillion threads on fuels and oil, with about 2 zillion different opinions. The nice part about it is that all of the opinions are right.

Only if your engine needs the higher octane. My 3.0L diesels like crazy on 87 octane and the problem goes away with 91 (and 89 most of the time) I run the 91 because for my boat it is a 100% solution to the problem.

My father in laws 5.7 Malibu is happy with the 87, so we never put anything else in it.
