Anyone have any suggestions please?Ok, read through this post as our 2016 FWD (20in wheels) is absurdly low. 42k total miles on it. I’ve been tracking it by Fuelly which uses the accurate method. We’ve only been averaging 14-15mpg in about 95% city driving, always premium 92 grade. It should be more to the 19mpg as rated. Accounting for any alignment or tire factors only would affect by 1mpg (2mpg in extremes). So we should still be much higher.
What would you all recommend I start looking into replacing? New fuel pump & filter?
