I've used a couple brands. Picked up some at truck stops, at the local auto parts store and at Fleetpride truck part stores. I don't worry particularly about the brand, perhaps I should, but I haven't heard enough comparison proof to figure it's worth worrying about. I do use it regularly when stored.
