the only way i know a car engine can be knocked(dead) is when the engine oil runs dry in the engine while running.are there any other ways a cars engine can be knocked

Sir, there are many ways an engine can be knocked. if youn run the engine without water, if your service is long over-due, if you use bad oil filter to service your engine, if you use bad spark plugs, by adding salt to your fuel. my friend there are so many ways.

lol wtf...salt to fuel What does that do?
