About a month ago I sent the same email to 7 or 8 gasoline manufacturers and a couple car companies, Chevron was the only one that responded:
Subject: Fuels – Technical Questions
I can't seem to find a trustworthy, definitive answer to a few questions- could you please help?
-Does gasoline really "spoil" after a month? Can it be "revived" by any type of fuel additive?
-Which brand of fuel stabilizer (if ANY) will TRULY extend the useful storage life of typical consumer gasoline?
-Does "premium" gasoline have a longer storage life than "regular"?
-What are the ideal storage conditions for gasoline?
I would really appreciate some knowledgeable answers, Thanks!
The answer Chevron sent me:
Thank you for the inquiry, and apologies for the delay in getting a response sent out to you. We are currently working through a back log of e-mails.
Chevron fuels (conventional gasoline, E-10 gasoline blends, and diesel fuels) have a shelf life of 1 year in a proper storage container without the need of a fuel stabilizer. A proper storage container include gas cans, and a vehicle's fuel tank (containers rated to carry gasoline or diesel). Shelf life can vary slightly depending on where you store the fuel. For best results we recommend that you store the fuel cool, dark, and dry area avoiding large fluctuations in temperature.
Storing the fuel in direct sunlight will increase the temperature variations, and can significantly shorten the shelf life of gasolines through the loss of the lighter gasoline components. Aftermarket gasoline stabilizers can prolong the life of a fuel, but we do not have any data on the effectiveness of those products, and cannot make a recommendation. Chevron does not market a gasoline stabilizer.
All grades of Chevron gasolines will have the same shelf life.
