Very true with our RAM. Chris
And my current Ram, old 2012 F150, my current BMW, my wife's old Mercedes and her current Infinti. In fact neither me, my wife or anyone else I personally know has ever had their lie-o-meter accurate within 1 mpg more than 15% of the time. The only time it has been close for me is on long trips with a few stop/starts in between, but the more I start/stop the vehicle the more it is off. It's almost as if these manufacturers just need to subtract 2 mpg from whatever formula or algorithm they get their mph numbers from.
My 2012 RAM is always within 1 mpg (usually less) if I stay out of my auxiliary tank.
My Cayman is dead on. Yukon isn’t close.
Depends on the vehicle but I still hand calculate and record every tank. Not sure why as it really doesn’t make any difference once you own the car.
I use an app to record mine so it only takes a few seconds of inputting the mileage and the volume of fuel used. The app does the rest. I generally fill out the lie-o-meter mileage, the cost per gallon, and brand while I am waiting. I started doing it for taxes, but it has become a habit.
