I have a 2018 2.5i Limited CVT that is just about to hit 30k miles. According to the built-in MPG calculator my lifetime fuel economy is 33.6 mpg (see photo below). However, I do periodic manual calculations and usually come up about 1.5mpg less. Still, that's 32 mpg over the life of the vehicle. Granted, I do a lot of highway driving but much of it is at 65-79 mph. And I do a lot of mountain driving too. The 34.8 mpg in the display is since I last set trip meter B 1,314 miles ago. Needless to say I'm real happy with the fuel economy of my Forester. I always fill up with 87 octane Top-Tier fuel.

Which Michelin tires do you have that you noticed the mpg drop with?

Is it safe to say the computer is pretty accurate?

When comparing the dash display to a manual mpg calculation, I've found that my Forester's computer calculator overstates fuel economy by about 5%. That's why we call it the exag-o-meter.
