I recently had a friend tell me that while adding Stabil will help fuel to be stored for longer terms it will also cause damage to your vehicle's engine if you use the fuel for that purpose. He said fuel with Stabil added should only be used for generators, etc and not for vehicles. This is the first I have heard about this and normally I would blow it off but the friend that told me this is usually pretty reliable on his information. Anyone out there have any problems or hear about problems using Stabil fuel in vehicles?
