“So, this isn’t a theoretical risk. Contaminated fuel causes the kind of damage that costs thousands to repair: injectors, fuel pumps, etc.”

“Before an engine manufacturer does this sort of repair under warranty they WILL check that you’ve maintained the engine and fuel correctly. If they can show you’ve used contaminated fuel, the bill falls to you.”
