302Sport

It seems like a lot of people on here say i heard from so and so dont run it or i heard so and so blew a motor while running it. But, when you talk with engine builders they say it is far superior to any pump gas. With that said it is in no way race fuel, but if youre on the verge of pinging with 93, the 100LL will keep it from doing so.....

I believe because AV gas is considered a "drier" fuel than pump gas.

Two onces per 10 gallons.

I've been running 33% 100LL AvGas for the last five seasons. I really don't know if I'm wasting money or not..... but nothing has broken, I've had no fuel related issues and that makes me happy. I'm sticking with that formula.

I hear ya, I run it in everything I have that doesnt have an 02 sensor. Never had a fuel system problem and most of the toys sit for 6 months to a year between uses........

Yep, I run it (straight, not mixed) in my Gator, lawn mower, weed whacker, generator, wife's Honda Ruckus and my old Vette (that never gets driven), etc.....

That beats the chit out of rebuilding carbs!!!

Street legal race fuel from Union 76 (100 oct.) has high alcohol content. Put some in my cobra one day and that biotch ran way lean.

Back in the 80s I ran 100 LL av gas mixed with 89 reg octane. This mixture was tested by gulf labs and came out to be 95 octane. I mixed 5 gal reg to 1 gallon av gas. I ran two blower for years and never had any issues. It was just a pain pumping the ave gas from a drum.

we are on an airport, so no problem, just pull the truck up

Its because it is considered a much "drier" fuel than race fuel or pump fuel.
This probably explains why engines that you have run it in are so exceptionally clean inside.
