Everything I have with a gasoline engine runs on Chevron 94 octane and always has.
I might note that I have never replaced an injector, fuel pump or throttle body and any vehicle I have ever owned. Really, if you can't spend an extra $7.50 a tank, you have to reassess your finances. This is especially true since the high grade gas, with no ethanol, gets 5% better mileage anyway.
We buy an astounding three tanks of gas a month for both of our cars; I believe the $22.50 is well spent.
