Best Gasoline for your Z

[mike100]

The only bad side effect from running 100LL was toasted cats- but a little bit mixed in my old cars so I could run N2o always worked fine.

It's not the octane that hurts the cats, it's the lead, AV gas is LowLead not un leaded!

Does anyone have any experience with ethanol-free gas? I've heard that ethanol is an injector killer. A little googling found a couple of sites that purport to locate suppliers of ethanol-free gas. Is it worth the extra miles to find such a supplier?

Yes and no. Eventually Uncle Sam is going to force this crap down our throats, so you might as well get used to it. If your Z has original injectors, they are not going to last terribly long with the ethanol-blended fuels. However, once you replace all 16 injectors with new or rebuild ones (SS guts), then you should never have a problem again (except for the degraded gas mileage).

Hope this helps.

As I understand it, it's not a corrosion issue requiring the use of stainless steel, but rather a difference in the materials used to protect the coil windings in the injector. Ethanol eats away at the material formerly used to protect said windings.

please beware of using av gas in your car it has additives that keep the gas from freezing @20,000 feet which really change the burn rate of the fuel and can burn up pistons . i would go get some unleaded 100 oct there are places in most towns that carry it .and unless you have a 12 to 1 motor you wont see any benefit from octane higher than 95 in our stk zr1s .
