According to the manual, the dash is supposed to have an option to display the Fuel Saver function is active. Can anyone verify they have some sort of indication that the engine is actually in fuel saver mode?
Yeah I wouldn't expect to see good mileage for the first 500+ miles. Then it should improve after the first few thousand as things get worn in. There are an awful lot of parts that rub together that need to find their happy place, used to heating and cooling and get lubricants absorbed into them.
According to the truck's computer, I'm getting an average 17mpg. Haven't had it on the highway yet, just on country roads with 50mph speed limits. It only has 460 miles on it so far. My calculated mileage is about the same, actually slightly higher, but then who knows how accurate these gas station pumps really are? And one fill-up at 3/4 of a tank isn't very precise. I don't know just how full they actually filled the tank before I left the lot.
I did have to reset the gas mileage in the comp when I got it. Of the 460 miles on it, 126 was put on by the dealer. I bought it off the lot, didn't order it. 2015 w/ Hemi. The economy in the comp when I drove it off the lot was 8mpg. I assume they had it sitting and idling a lot while checking it out and showing it to customers. Resetting it made an immediate huge difference. So I only see fuel calcs based on my driving, not their idling.
