Okay, then what is the condition of the air cleaner and plugs?
Just as a reference, I normally drive quite conservatively and I am getting 18mpg city/28mpg hwy and 23/24mpg combined. My only mods are headers, hi-flow cats and Borla exhaust. I disabled the CAGS as soon as I got the car, but I still shift first to fourth a lot of the time because premium unleaded costs $US6.00 a gallon here!

I just did a complete tune-up on my 02 Z06 last week. According to the DIC I was getting 29.2 mpg on the interstate driving to and from the "Run to the Sun" at Myrtle Beach, SC. My average around town there was 22.7 before I reset it to drive to my home in the NC mountains. That was driving sensibly since my co-pilot does not appreciate my car's abilities as much as I do. Our cars can get great mileage if driven carefully, but what fun is that?

I just bought my vette a few months ago and have been noticing i am getting terrible gas mileage. The car is a 99 vert 6sp with 80k miles. Acording to the DIC i have been getting between 18-22 mpg. In reality i am getting 16-18 if i divide the miles driven by the gas consumed at each fill up. I recorded the best mpg so far yesterday at 18.2mpg about 260miles with 70% hwy driving and the rest normal city with no spirited driving. The tires are all at 35psi and i dont ever run with the AC on. Also the car is stock besides a zip tie mod intake.

Seems very normal here. Have never gotten better than what you posted unless on a very long freeway trip when we use 6th gear. And that isn't very often. We just figure they are fun mpg's.
