If someone can sell me or tell me where to buy the synthetic ultra that would be a great help. None of the dealers around me stock it in anything bigger than those little mix bottles that make 2.5 gallons. They will not order the gallon for me cause they have to buy it by the case and are afraid they will not sell it all. I hate using those little bottles so any help would be appreciated. If I had to I suppose I would bye it by the quart if that is even possible. Thanks in advance for the assistance.
