Slick;

Jack is right on all counts.........We used to use AV gas in the dirt track car,it ran very good,but AV gas has a number of additives for high altitude and air cooled avaition engines and will leave a nice black coating (have NO clue exactly what the stuff is) through out the internals of your engine..........

I have done a good bit of research on octanes and such and by all counts burning more octane than you need is just wasting money,higher octane will not make higher HP.......... actually the minimum octane needed for any given engine will make the most hp.........

Some people use a little higher octane for added insurance against engine knock while racing and running at prolonged high rpms.........

The drum (55 gal.) I have of 110 leaded gas right now states on the tag that this fuel should suffice for engines up to 15 to 1 compression,around here we have 110 and 114 avaliable in drums,my race motor is 13.5 to 1 compression,that's why I use the 110...........
