Hey folks,
I had car serviced last Friday and ever since im getting 21-24mpg, prior to that for the same journeys it was 35-37mpg and longer journey would be 42mp avg.
I had a engine flush and fuel treatment this time.
And cannot blame the weather and its been alot milder lately. I double checked the air filter to make it was seated properly, so im at a loss to explain why the mpg ahs dropped so much.
I always run on E5.
Any suggestions?
