Was chatting with a Fedex driver just the other day who did the opposite - he said he put gasoline in a diesel truck. I would have thought that the size of the nozzles versus the size of the car intakes were such that you couldn’t do this sort of thing but obviously you can.
All I can say is that it’s a stunning level of incompetence. If they fail at something like this - what else are they likely to fail at?
What effects did the Fed ex diesel suffer? Did he tell you?
