If you leave diesel sitting for a long period of time such as at the end of the boating season it will separate. This is not good. Fuel separation can lead to problems with gum formation poor cold starts, and overall lower performance.
Fuel goes stale. Everyone has had an experience with a lawn mower, hedge trimmer or even a bike or car that has been in storage for a season or longer not starting up. Not only does stale fuel prevent your engine from starting right up it can lead to damaged pumps, injectors and fuel lines...
