Many of us have had the experience of gasolene deteriation (smells like BAD paint thinner). This process happens much faster than most people realize (30 to 60 days, 120 to 180 days if it is chilled as in cold climates).
The fuel systems on injected engines suffer greatly due to sticky deposites resulting from attempting to burn 'OLD' gasolene. Use of a reliable fuel preservative when storing equipment is good insurance against big expenses at the repair facility and/or unscheduled stops along the interstate.

What few people know is there is a bacteria that likes to grow in diesel fuel which is stored for long terms (Maximum 1 year) at room temperature and above. Use of diesel fuel conditioner before storage is a good idea.
If fuel does turn bad, BEFORE THE ENGINE IS STARTED - fuel should be drained, fuel filters changed, and the system flushed to get as much of the old fuel out of pumps and injectors as possible. If this sounds like a mechanic's job - It is.
