I pulled a fuel tank from another car and had to drain it. So drained the fuel into fuel cans and then put one can (3 gallons) in the S550 every few days.
The Check engine light came on because the car thought the fuel tanks level sensor had a fault .
So I take it, the "system" doesn't like it when you add 3 gallons drive enough to add 3 more.
Next fill up running it down to 1/4 tank then filling , cleared it. But an odd quirk.
The Ford app Listed the fault in the messages .
