Fuel Gauge

[Downtown Canada]

Has anyone noticed a lag between when the fill up their tank at the station, and what the fuel gauge indicates?
For example:
My tank was shown to be at 1/4.
I filled up my tank completely, turned my car on, and the gauge only showed that my tank was 2/5 full, when it should be...at FULL.
The next morning I check my gauge, and it finally shows it at full.

I've fulled my car up 3 times so far, and it's always had a lag.

I’ve filled up about 7 times and never had a lag.

Not a thing on the S550s- would get into dealership / should be easy fix

While I didn't exactly experience that, one thing that I've noticed is that, after a drive around lets say my gauge shows it is slightly below half a tank; If I start my car the next day, the gauge will show it is slightly above half a tank. I've always found that super weird for some reason.

Haven't had to fill my Mustang tank yet, but my '19 Taurus does the exact same thing. It's pretty weird but you get used to it.

No issues after multiple fills on mine.

Thanks for the feedback everyone! I'm going to fill up one more time and see what happens...then take it to the dealer if it persists
