Reset in car mpg on dash after dealership refueled car....

Started out at 28mpg on car and Onstar .......and then started dropping.

Car now says 26.2mpg

Onstar lifetime mileage now says 19mpg (started out at 28)

I never go over 2000 rpm and drive very easy to try to get great mpg.

New car, city driving, speed all are factors in foal mileage. Let the motor settle in, drive the car a little bit. I am sure you will see the 31 mpg (US) city we are seeing with our [email protected] 4000kms.

I think a better measure is the more recent results than the lifetime results because the engine does need to settle.
