100 octain low lead
VP makes a great 100 unleaded.
I am almost done with aircraft maintenance school and for the cost of it I would just go with low led.
Now if you had a desiel car or truck run the jet fuel in your car.
When my dad had one he would fill up with it when they got ready to fill the tanks. It would be dirty fuel but desiel fuel is dirty. Free Gas

I know some guys that use a leaded race gas but they are older EFI cars that have cheap O2 sensors.
