Ours gets 41-42 on the hwy. On my wife's commute to and from work she gets 37-39. Hand calculated mpg and computer mpg vary .5 to 1 from each other, so, I have found the computer to be fairly accurate. Keep it out of dynamic mode, do not make jack rabbit starts, do use the cruise control. Also, stop as little as possible. Look way down the road and anticipate traffic lights. We leave the engine start/stop off, that **** thing is very annoying.
We did have to add DEF at about the 2000 mile mark. I suspect it was not topped of before we accepted the vehicle. All we got was a warning notice that the DEF was running low. Wish there was a DEF gauge. Price at the Pilot truck stop pump for DEF was 2.79 a gallon. Owners manual says not to fill from DEF pumps, so filled a container and manually filled the tank.
Many areas will start using winter diesel soon. You will notice up to a 10% decrease in fuel economy. It is the curse of winter driving.
Got the growler valve stem caps in the mail last Thursday. They look better in the box than they do on the stems. My wife likes them on the car though, so, there they will stay.
While on a long trip you will notice when the particulate filter regenerates by a decrease in instant mileage. For us on a 800 mile trip that happened about every 250-300 miles. That is more often than I like. Maybe it will get better with break-in.
