We have it here in Colorado and the fuel milage with it drops in half. Right now it's more expensive than unleaded( not sure how long that will last). It might run great in race engines, but I wouldn't classify our airplane engines as racers, or not the average flyer anyway.
Those 70 monte's are bad dudes when set up right, must be lots of fun!
That's the problem main with the stuff- less Miles per Gallon. Everybody that I've talked to that has ran the stuff, didn't keep using it. The Monte is alot of fun. The 454 has turned the back tires into slicks so I'm going to have to get a new set this spring.
