    Just back from Vegas. Going I used 87 octane and back 91. No difference in mileage. In both cases I got 15.8 mpg.

    Once you get about 5000 km on the motor you should get better miles, at 15000 km the motor is all worked in and you will get the most power and fuel economy.

    I would pull some spark plugs and look at them, my 02' Z06 seemed a little "flat" at first, I looked at the plugs and 4 of them were gapped at .125 +, and the other 4 were over .080, the gap called for .060, so you may want to check that.

    They can plug your trucking into a Tech II tool and see if there are any problems with the electronics

    Check your tire pressure. Take your 3rd row seating out and any other dead weight. Try using the cruise control as much as possible. Each one of the 3rd row seats weighs 55 pounds. Drive at 65 to 70. An extra 10 miles more an hour can really eat a lot of gas. Hope that helps.
