I think gas octane is a bit overrated. 87 is perfectly fine for an engine that's in good shape. I use higher octane when readily available, but don't worry too much when I use 87. Higher octane only means it can withstand more compression without self igniting. Using 87 in your engine without hearing any abnormal noises or miss fires only means it is in tip top shape personally i think using non ethanol gas is much more important!

If you have one of the RTP, LTR or MCX engines it normally won't be an issue. If you have one of the LS based engines it can be a problem.

I just keep a couple of bottles of octane boost in the boat for just in case.

I've done it w the LT1 and MCX no problem.
If you need octane, a jug or 2 of race gas to mix in would be more effective than the octane boost cr@p.
That stuff never worked back in the day. Not sure if it's gotten better.

I freak out because I cannot find ethanol free gas during vacation. That's my MCOCD coming out I guess.

These motors will pull timing if they start to ping due to low octane. So at most you will have reduced power that most likely you will not notice. I always run premium in my LT1 as if generally has less ethanol in it (from select stations around my house), and because technically it requires it.

Premium has less ethanol in it than regular?

Learn something new everyday. Thanks!

+1... Knock sensors retard the timing to eliminate the knock and ping.
