AvGas in your Stang?
I can get 100LL octance aviation gasoline
up at my local small airport easily.
for use on the weekends when wanting to run higher boost levels
This gas still has lead in it.
Will that hurt anything in an emmissions legal engine
to switch back and forth from unleaded to leaded?

RE: AvGas in your Stang?
I do not reccomend av gas in a car. Think about it for minute, av gas is designed to run in a realitivly low RPM, non supercharged engine that operates at very high altitudes, the exact opposite of where car operates.Even though it hasa pretty high octane rating, it is measure in a little different way than gas for cars. Running av gas is a left over of 1960's thinking, you should look into real race gas if you want to run higher boost. Rocket Brand race fuel has a nice 100 octane no lead gas that would work great.

This doesnt say much about avgas but should help you understand octane and what the octane rating really means.

RE: AvGas in your Stang?
Av-Gas is a good high-octane fuel....under the right circumstances. It is run in aircraft engines that conparitively speaking are large cu, per HP low-rpm situations (many small 4-place aircraft run a 320 cu, 4 cylinder engine that produces 160 hp @ 2450 rpm) . Some other aircraft are supercharged and turbocharged up to 50" or more of manifold pressure. The big problem with av-gas, even what they cal 100LL (for low lead) has more TEL in it than Regular automoitive fuel from the 1960's. In a short time it will hurt your cats, valves, injectors, tb, O2's and most any other system it comes in contact with. It is old technology and very harsh on equipment not designed for it. I used to run it in my 1966 mustang and it LOVED the fuel, however a post 1980 or so vehicle just cannot handle it without damage, sometimes severe.

RE: AvGas in your Stang?
thanks, i'll just break down and buy 30gal drums of 100oct race gas when I get to that point
and ya love my airplane's displacemet : 520 cubic inch 6 cylinder putting out 285hp at 2700rpm
sounds like a dragster at idle with its almost straight thru exhaust.
