It's not really upgrading/downgrading, octane number is nothing but the ability of fuel to tolerate knock. it doesn't give you any extra power.

Just concerned about pinging the motor to death. I've never had a problem when running ethanol free premium.

While you are correct about the higher octane fuel in itself having no impact on power, lower octane fuels may contain more ethanol which has 33% less power to it. So definitely check what blending is being done to the fuel.

I run into people occasionally that run premium in their econobox since its the 'best' fuel for their car in their mind and claim all sorts of better fuel economy and generally running better which is obviously total crap. Higher octane fuel has no positive impact all else equal unless required.

Great info Brock, thanks for sharing. Now i have the dilemma of dropping octane to factory recommended and deal with the ethanol or stick with premium (92 octane) which i can get ethanol free?

Of course, we would never suggest going against the MFG. recommendations... but I can tell you that WE run 87 octane pump gas at the drag strip and on the street in all applications except in exceptionally hot climates and/or extended wide open throttle use.

Here in Ohio it gets in the mid 90's in the summer, been doing it this way for years and our fuel is 10% ethanol pretty much everywhere.

That said, if you ever hear a single ping - or if you THINK you hear one. Head to the station and get some 93 ASAP. Detonation kills engines quickly.

I'll check the MFG recommendation. Thanks again for the information.
