Yes, 10 mile per gallon on matter how you drive. 10mph to 110mph so I drive 110mph any where I go. ------------ wynn at 8/18/2002 1:17:20 PM

Fill it up with 89 or 93 and it will show you a different "animal" under the hood and improve MPG a bit too.

Is the 8.1 a high compression engine?

I would call 9.1 to 1 on a large bore 496 a high compression motor for sure. GM's knock control "let's" you run 87 but you loose a lot of potenail power on a warm or hot day with it.
