My F250 is 6.2 gasoline powered. it even stated as much on the service report. But it detailed out a diesel oil change!!
I've got another story like that one. My mother inherited her father's subaru outback from the estate. Prior to him expiring and when he was still out and about, she asked him to get the timing belt done because the car was way overdue. In his decline over the next year, all the paperwork was lost during moves and so when she got the car, it was unknown whether the service had been done.
I was pretty booked at the time, so when the car showed up, they took it to another local shop for a new timing belt. The service writer was told that it was highly likely the car had a new belt and if it did, please stop, button it back up, and the bill for the exploration work would be paid. 6 hours after they dropped the car off, the phone rang and it was ready to pick up with a new belt installed (supposedly). My father asked to see the old belt when paying the bill ($1150) and was told that it had been thrown out and their dumpster emptied (bullschit!). He bit his tongue and paid the bill and came home. I looked at the car the next day and half the screw heads on the front of the engine were dirty and clearly hadn't been off the day before. The mechanic had obviously pryed the cover open, scoped the new belt, and slammed it back shut.
A few months later, going through papers from the estate, a service receipt for a new belt done at the subaru dealer was found confirming the suspicions of being ripped off. But not much you can do. Not enough to go to court over. Just have to shut up and eat schit and warn your friends.
The wife is looking for a new-to-her car, and it's a challenge.
I'm going to keep driving my old beater with a heater until I can't keep the wheels on it anymore. I don't see hw anybody can afford new, or even non-junker used rigs these days. It's beyond crazy.
