2012 C250 Fuel showing 11-13 MPG on computer
My display shows After Start and After Reset that my C250 is averaging 11-13 MPG. I changed the Spark Plugs and engine coils recently because of a code for the 3rd cylinder but my gas mileage seems to suffer. The car has 85k miles on it. I've really only driven city in E mode with light acceleration at stop and go traffic. Any other parts I should look at to get this car back into the 20s MPG?
