Leaktroit

Derogatory term for Detroit Diesel two-stroke Diesel engines, so named because they tend to consume lots of oil and leak oil. Some say that, on these engines, if you didn't have to add a gallon (or two, or three) of oil to the crankcase every time you stopped to get fuel, something was wrong.

Me: What engine do you have in your truck?
Truck driver: It's an old 12V92 Leaktroit. Thing drinks oil like breakfast but I still love it.
