Hello All,

I have 2016 F15 5.0. I got it as a Executive Demo with 1,600 miles on it. They told me that it was the performance center car, so it must have been through mid and water and all kind of stuff. And i do see lots of mud all of the car. Long story short i get 12.5 mpg highway and 11 mpg city.

The dealer said nothing is wrong with the car they said they get 17-19 mpg when they took the car.

I still see lots of mud on the radiator and I?m thinking that the air filter is dirty as well. The dealer said they will charge me if they?re going to replace the air filter or the anything to do with mud from the performance center.

Is anyone having any issues with gas millage with there F15?

I have a 2015 M6 and it gives me 16-17mpg.
