So I had my C6 for about 45k miles before selling it. I rarely got in it and always tried to hyper-mile it on the highway. I'm thinking about getting back into a used C6, and it seems the best criteria would be to look at the average MPG. I've seen it down around 9 or 10, whereas I think I had it around 21-22. What is your average MPG and can this be reset or it's definitive for the lifespan of the vehicle?
13.x on E-85. 15-16 on E-10 93 octane.
I really wish it got better. I think it's my driving style and wide sticky tires.
In most vehicles I get above average mpg.
I either have something mis-configured in my LS2's tune, or its E-Force supercharger gives it extraordinary mileage. When cruising on the interstate at 65mph, I often see 37.0 mpg (average) in the DIC.

Sometimes a tune will skew the data sent to calculate the MPG.
On my Dodge diesel the 'stock' setting gives me numbers that are 15% high. If I click it up to the max HP tune the calculated MPG numbers are more like 30% high.

I have had so much fun with my C6 for 1 year plus 4 months!
I really have not checked the mileage. I will be driving to Carlisle and will see what my Corvette gets. Then again I may forget because of the fun factor.
I got 21.1 MPG for the round trip of 500 plus miles. I did not drive above the speed limit and was stuck in traffic for 1 hour just South of Carlisle. It sure was hot there.

2013 GS Coupe M6 - Average 22.7mpg over 16,000 miles
I frequently travel long distances with a 2010 Callaway GS Convertible A6, a 2011 Callaway GS Coupe A6, a 2008 Z06, and a 2013 427 Convertible, and I always have to put more gas in at refills with the 2013 GS M6. Less horsepower and more gas.

I recently complete a 2800 mile road trip which included bursts up into the triple digits, stop and go traffic, cruising at 80 plus, and playing with the paddles into the twistys. I averaged 24 mpg in my ’13 GS.
