Before anyone is tempted to school me on octane, I know what it is and how and why it works the way it does, I was just curious if anyone here uses 87-89 octane in there LGT.

I will use 91 or higher, but again I was just curious if anyone uses 87 and what the results were.

I believe the compression ratio of the LGT is 8.2:1 which don't seem all that high, but the one place someone could school me is how compression ratio's effect turbo charged cars. I know that turbo's increase pressure but 8.2:1 seems kinda low. My '93 Probe GT had a compression ratio of 8.6:1.

Anyway, just curious....
