fuel octane decal

[X33RS]

Wasn't there a fuel octane requirement decal located somewhere on Z28's....or no??

My Z has 2 original decals on the core support.  One is the usual emissions decal, there is enough legible on it to determine that.   The other decal closer to the radiator cap is not legible anymore but I can tell something was there.

I'm guessing it was either a coolant decal or fuel octane.

Any help appreciated.

Nope. Even ZL1 Camaros [12.0 compression] did not have the label. L88 & ZL1 Corvettes did.

Thanks William, so it's safe to assume that is likely a coolant decal on the passenger side core support.
