mostly back roads at 40-50 mph. Rarely over 60 so it doesn't get into 6th gear. I used to post about the bad 15-17 mpg in leaving it in eco mode. I think the gas has less ethanol lately contributing, but I noticed an immediate mileage increase after I left the battery disconnected over night. Always run 5w-20 dino oil.
I have noticed a mileage increase lately, I thought it was because of some possible benefits after doing 200 miles on an 85 mph toll road. My truck seems to shift into 6th at about 62 (3.55's w/17's). How many others have noticed this? I haven't seen any other comments about this, you really have to be watching your speed and rpm closely.
