On our 2018 CRV, it starts off with a mileage that is based on recent driving. For example, after a fill-up of mostly highway driving, the distance to empty will start off around 350 miles. After a fill-up of mostly city driving, it will start off closer to 300 miles. Here's the interesting part, though. As you drive, it will NEVER increase the distance to empty calculation! If you end up driving a bunch of highway miles, it will just slow down the distance to empty value.

On our 2013 Volvo S80, the distance to empty value will actually INCREASE if you start driving a bunch of highway miles. So, it may start off at 300 miles, but within 10 miles of mostly highway miles, the distance to empty value will JUMP up to 350 or even 400 miles.

The CRV will NEVER increase its distance to empty. It will only slow down the drop of the already existing distance to empty value. So, if it starts off at 300 miles, and I start a long highway run, it will stay at 300 miles for many miles, and start slowly trickling down the distance to empty from there.

How does your car handle this calculation?
