Ruined MPG calculator

[porterhousestk]

This morning my '24 Ecoboost started dropping MPG by the second, ruining the nearly 9k miles & >400 hours trip calculator I've had going since day 1. I do mostly city driving so I had a consistent 23.8 mpg for a while now... I'm not sure if there was an OTA update that messed this up, but I surely wasn't driving hard enough to drop 3 MPG within half a mile.. Has anyone else experienced this?

Can't say it's bothered to cross my mind.

Are you going to take some time off from work to recover or just power through?

Seriously ... I record all my mileage and fill ups elsewhere, so an inadvertent reset won't result in the loss of anything. Besides, the MPG calc in any car is never accurate.

Lol i'll just have to get over it. I should have been keeping my own notes if I really cared. Always trying to get that average mpg # as high as I could. I was looking forward to a road trip coming soon to see how high it would go.. I knew it wasn't perfectly accurate, but it was fun while it lasted.

I've purchased a dozen and a half new vehicles in the past ~20 years alone. While I don't go out of my way to NOT do it, I have always seemed to leave trip ODO #2 alone the entire time we owned it. It was always within a mile or so of the last three digits of the actual ODO when I looked at it trading it in/selling it.

Be careful in the Mustang. Many S550 owners on here ran out of gas when they thought there was an extra gallon or two after the gauge said zero miles. As they found out it was very accurate.

I didn't buy a Mustang to keep track of miles per gallon. One might watch milage maybe to indicate a potentail problem. Losing data over a long period would more than likely mean nothing as the the most reacent would be more relevant. If one is keeping track they should know what is the norm for their drive style. So many complaints that anyone with some initiative should be able to work around.
