We have e10 here. Ive been running about 16° timing on my tbird with no detination.

Possibly even more than that. Plus, alky won't detonate to the extent gas will, and it's also a small part of why alky engines can run a little more compression, among other reasons.

It has it's bad too..it's not as efficient as gas. But that's sideways from the topic.. lol

I figure my gas mileage went down 7% as they did the change over while I had a 50 mile commute each way. Lost a bit of power too. And when I advanced the timing for ethonal junk if I filled up at a gas station that didnt have the proper mixture or hadnt changed over yet it would ping. More timing is fun, but quit watering down our.gas.

jcassidy, do they have a texture to them or are they smooth and just colored looking?
when i did the headgasket on my brothers grand prix the first time(not long after he got it) his valves were fine and smooth but the second time abouth 30k miles later they looked like those but had a textured feel to them.
he had a bad habit of letting his car idle for real long periods of time and i thought that had something to do with it.

Here's what mine looked like. White valves seem to be the norm.
