Leaded vs. Unleaded

Thare is no point to run race gas unless you have some serious performance parts. Leaded gas will mess up your o2's and your cats if you are running any. If you run leaded gas just acouple time it will be ok, but alot will cause problems to your o2's and cats. Check at VP's website LINK

I ran AvGas (aviation fuel 108 octane) in my Kawasaki ZX600R and it ran GREAT on it. It also has a nice smell but it coated the tip if my exhaust with a white frosting. On emission restricted vehicles, you have to be careful about running any leaded fuel because of what STANG GT said ... it will really mess up the sensors in newer cars because of the lead particulates in the fuel. It will coat over and mess up most of the sensors that are in contact with the fuel or exhaust. That's why it's mostly just run in race engines and in older vehicles that don't have those types of "sniffer" devices. I agree with ya too ... with most of our engines, the additional octane would just be wasted.
