Hi guys, I know there are lots of threads in the forum about this, but i did not find what i was looking for. I just bought the car a few days ago and I am concerned about the gas mileage the DIC is showing me i am getting. When i set it to readout the instant fuel economy, it is horrible. Like 13 everywhere i go unless i am cruising barely touching the gas on flat highway at 55 or more and it shows me maybe 20-23 MPG. Average MPG says 13. I reset it a few days ago.This is certainly not what i was expecting. Car is running great, only has 38K on it, and Oil life is at about 96% I see people are saying replace the plugs and filter and all of that, but shouldn't the pugs be fine considering the mileage i have on the car? I would appreciate any help you guys can give me. Thank you.
