2022 Ford Super Duty Lariat 6.7 Diesel
 

I filled my truck up on a Thursday and gauge said 1350kms to empty. Been driving it everyday, now it is Wednesday and the gauge shows 1296kms to empty before I left work...20kms later the gauge went up to 1308kms to empty. Should say around 1200kms to empty. Does this mean something wrong with fuel tank sensor or a display issue? Anyone else have this issue?

Was this only one time or every time?

If it doesn't happen every time , it will be difficult for the shop to determine any cause because they need to be able to duplicate the problem, which if they cannot, they can't be sure they fixed the problem when returning the vehicle back to you.

I have had the truck since May and so far this is the only time I noticed. It is just confusing watching the numbers going up as I am driving instead of going down. I will keep an eye on it to what crazy things it will do. Just curious if anyone had the same issue.
