Recently a friend of mine showed me where they sell 110 octane racing gas at the pump, only problem is that it is leaded fuel, he tried to get me to use it, says he mixes about half 93 and half of this leaded 110, I am a bit concerned about this, as it clearly says unleaded fuel only, but he has had no problems using this mix.Any suggestions on this?

If you have cats on your car, I advise against it. I run 116(leaded) at the track but I have no cats

I have had the cats removed and the other things that were in front of it, just mufflers

your car will not run any faster, you'll be wasting money. You want to run the LOWEST possible octane WITHOUT detonation.

true, higher octane is for vehicles with higher compression or boost so the higher octane you go the more power you hopefully are pushin through the engine. our cars stock should take 87 no problem but if you have a tune for 92 or so and it detonates on 87 or 89 then you want to stick with 92 and no higher. it has to do with the burn of the fuel.

Exclusive use of Leaded fuel will foul the cats, as well as damage the O2 sensors.

The sensors can take more than the cats, but if you always run leaded fuel, they will eventually go.

Waste of money, plain and simple!

+1 Unless you get a custom tune specifically for the octane rating you will be wasting your money. The 110octane isn't actually Leaded like it used to be. It's actually 110 Low Lead. Yes still is a Leaded gasoline, but has far less lead in the fuel. Airplanes run on Low Lead as per Gov't regulations. My best friend is an airplane mechanic and he asked me if I wanted to get some 101 low lead that his airport supplies. The fuel is blue colored to distinguish the lead additive from regular gas.

waste of money unless your trying to cure a detonation problem and in that event its just better to back the timing off. the only benefit i would see would be on a boosted car because you would be able to add a lot more timing.

What would be considered a enoughhigh compression to benefit from 110 octane?
