My brother, who buys car magazines/is a car spotter, checked the oil on his Volvo and it was low, so he put a bottle of oil in it.
It started cutting out, smoke would pour out of it, and it was called every sort of not good enough bastard possible.
So he’s sat in the pub and after an entirely riveting discussion about cars with another bloke starts to talk about the problem that he was experiencing.
Had he done anything to the car recently?
“I filled the oil, it was a bit low I put a bottle in”.
“Really ? it took a whole litre to bring it up to the full mark, maybe it is using oil ?”
“No, it wasn’t a 1 litre bottle, it was a 5.”
*Stunned silence* followed shortly after by *many tears of mirth*
