I have access to free leaded fuel, around 110 octane with no ethanol. my friend used it in his banshee and worked nice. I am looking at doing this for performance. It is free and want to use it. so what is the good/ bad/ ugly about using it.

I don't think you will see any added preformance, but it should be interesting to see what the 110 octaine does to the engine.

If it's free with no ethanol, use it.

Free is good! Higher octane has a slower, more sustained burn, but that shouldn't hurt anything in your motor. Miles/gallon may not increase, but miles/dollar will be awesome!

I would love to share but might get some peoples in trouble. I dont really care about performance just free. Going to look into running it into a 3.0 merc. Should not be a problem i am thinking
