What damage can water do to a diesel engine?

What do you do if you put gas in a diesel engine?

The flash point changes: When gasoline mixes with diesel, the first thing it does is change its flash point. This means that the diesel fuel will have a lower flash point and prematurely ignite in the engine which could lead to serious engine damage in the long run.

What happens when diesel fuel goes bad?

When diesel goes bad and gets old, gum and sediment form. This reaction happens because of the reaction of the fuel and oxygen together.
