I know most are thinking "who cares about fuel economy, you drive a Vette!" Ever since I bought my '11 GS a couple years ago, when I fill her up the "range" on the DIC has always read around 411 miles till empty. Well yesterday I filled her up and the range on the DIC read only 248!
What happened to my other 160 miles?! I have not changed anything on the car between the two fill ups except what the dealership did by replacing the RDLCM mentioned in my other thread. But I would not think that would change my MPG.
The tire pressures are exactly where they need to be and my K&N air filter is clean. The car has just over 50k miles (yes, I do drive my car). I'm wondering if it is time to change spark plugs or fuel filter or something? Any thoughts? Or should I just wait till next fill up and see what happens? Thanks!
