Q: AMSOIL will be using a different formula for its XL-7500 Motor Oils. Why did AMSOIL change the formula?
A: Our XL-7500 oils are the oils of choice in the retail oil change market, and primarily because of warranty concerns the customers in this market require API-certified oils. In order to obtain API SL/ILSAC GF-3 certification and still remain cost-competitive with the other oils sold at retail oil change outlets, we had to change to Group III basestocks. To obtain API certification with our top tier basestocks would have priced our Dealers out of the market.
