Just curious if anyone else is running AV gas with any side effects. I realize it can clog cats, but with them gone is there anything horrible about leaded gas? I get the stuff free so I figured it is better than paying 2.20 for 93 out here.

If you don't mind frying your cat, I guess not. Japan runs with 100 plus octane all the time.

Probably good for a rotary to run on leaded due to the extra lubrication. Don't know how easy it would be to come off it though.

Sunoco doesn't recommend it.

Sounds to me they are just trying to sell their product.



Couldn't I just use AvGas instead?

Aviation gasolines are leaded and not taxed as road fuels, either of which make them illegal for use on public highways. Aircraft engines are also essentially low engine speed, constant throttle applications that must work well at very low atmospheric pressure and temperature. Aviation gasolines are blended to work well only under these very specific circumstances, and do not perform as well under high rpm and high load applications.



So its illegal, ok I don't care. Low engine speed, true but that doesn't mean it won't work at high engine speeds. Its still 100 octane, just has lead. Constant throttle, low pressure, and low temps...that statement couldn't be further from the truth. Obvoiusly sunoco hasn't flown a 152 in the dead of summer.



So what about rotary aircraft that use 100ll? After all we put those aviation apex seals in our cars...

I like my cat, she lays on my bed at night with me. We run C16 sometimes, I just need to know if the lead part has any side effects. I'd rather run free 100ll than pay 5-7 bucks a gallon for C16 or 2.20 for 93 pump.

damn, gas is cheap where you are. We pay upwards of 2.60 for premium.

we get often TurboMark and FastFreddy. But we have no emission controles.

Sunoco makes avgas too.



I don't think they're commenting on will it work or will it blow up the car, but will it work optimally or as good as automotive leaded gas. If it was only about octane, leaded and unleaded, they'd only make about 4 blends of gas. If you run down their list of racing fuels you can see they have different burn rates, rate of vapouration, etc. Three different fuels may have the same octane, but they all have different purposes.
