Read a little closer guys. He said he lost 2 mpg. He didn't say he was getting 2 mpg.

seems highly unlikely.

What plugs did you use? Did you verify the gap?

Did you reset the trip computer or something? If the old average had say, long highway trips with steady cruise at 70 your overall milage will be higher vs a reset and just intown driving
