Speaking of V-8's and fuel consumption, my 1991 Caprice with a 5.7 gets 26MPG on the highway at 65MPH with cruise control on.

All because of the 2.56 rear gears.

I just sold my 2000 Vette and bought a 2006. It was a fantastic car. I had the Z51 Suspension package as well.

The only problem I had was an issue with the fuel gauge. In the summer time, when the tank got a little bit below half, it would sometimes just go all the way to zero. Strange!

As far as fuel economy, I averaged right around 22.5 MPG between highway and city, but would often see around 28-29 on the highway if I didn't go over 70 or 75.

Otherwise, the car was pretty flawless. Loved it to death -

I have had my 2000 C-5 for 6 years now, car is like new, a little over 15,000 on it. This car has been great to me, and I will never sell it. I plan on giving it to my son or daughter in 5 to 8 years. The car handles like a race car. I have done some mod's for very little money, she is a real runner. I feel Chevy built a real American muscle machine. The car is my pride & joy. The Corvette, the true American sports car.

Not that I care about MPG when I bought my new Vette, but I easily achieve 30 mpg on the digital read out. Go into the city, and my average drops to 17. You don't buy these kind of cars to quibble over gas. If you want to know the biggest expense, it's the runflat tires. Other than that, they are bulletproof.

Add another 160 per rim when the batteries go in the TPMs. The batteries are not replaceable. I bought new rims and changed mine out. They do go bad in time. Kinda pricey tire monitors to read from the dash.

I have a 1999 Corvette. I have used my own calculations, data from the car's computer, and yes I have gotten 33 mpg. My Vette has a Vararam air intake and a B&B exhaust with 4" tips. You need to take into account that a light weight car, a lot of air in, a lot of air out, with high horsepower. The car breathes well.

I have a 2000 Corvette and I am experiencing exactly same things - on summer sometimes it shows that I have no gas even though I still have a little bit less than a quarter of a tank. When driving in city, I get around 20 MPG. On the highway in longer trips, I got almost 30 MPG. I bought the car in 2010 so it was 10 years old already, I have owned it for 8 months and no single issue - everything works perfectly.

I supposed the only way to accurately measure it, is to calculate the number of gallons at the gas pump delivered, divided by the # of miles traveled. Say from a FULL tank to the low fuel light on. Repeat a couple of times to check precision.

If anyone is traveling soon, please post results.
