Hey guys, I'm a new f150 ecoboost owner on my second tank. When I first filled it up it read 785kms to empty. This time it read 682kms to empty. Any thoughts on why the 100 km difference? I don't think I'm driving it any harder than the first tank

The first tank is very optimistic, it bases everything off of factory settings. The computer logs your mpg so as time goes on it becomes more accurate since it basis it on the real world results you experience with your truck, not factory settings.

Ah ok, that makes sense. Thanks. Just was a shock. I was pretty stoked when I saw that many kms per tank.
