So I think.. I've decided that my truck needs a trip to the dealership. At first I thought the combination of winter fuel, non completed regens, and slightly heavier tires was the cause but something else must be a cause of a large drop in fuel mileage.
Mileage is down all around city and highway.. It seems like it struggles to increase in average mpg but drops significant average mpg with very little stop and go
I just made a 766 mile round trip that i've now driven 4 times. First 3 times I've driven it my average fuel mileage was 21/22 mpg. I drive it the same way every time and ambient air temps are always ~high 30's low 40's
I just drove it this past weekend and I'm sitting on 16.5 mpg.. Complete crap.. Everyone says to do hand calculating and I do.. I find it hard to believe that the extra 32lbs in rubber would kill 5 mpg. Fuel and air filter are brand new. Is it realistic to think the dealer will do anything? There are no check engine lights. I hate thinking that I should need to program this thing
