Fuel Preservative

[Phil G.]

It's my understanding that gasoline is less stable than in the past with the additives that are input at the refinery (no I don't have proof for that claim). For those of us who do plan to store our cars over the winter months, I personally feel more secure adding a reputable fuel stabilizer to a full tank of gas prior to storage. I'm not alone in this view. You are certainly free to do what you wish. Others claim that an oil additive is needed as well, as both gas and oil tend to absorb ambient moisture - even with a 'closed' system.
