Test Results and Assessment:


The label on this product states API Service SA/SB. API SA oils have no additives and SB oils should have ZDDP anti-wear additive. An oil cannot meet both of these service categories. This product meets neither as it does contain a viscosity modifying additive and does not contain sufficient ZDDP anti-wear additive to meet SB. API SA is not suitable for use in gasoline engines built after 1930 and API SB is not suitable for use in gasoline engines built after 1951. The label on this product fails to give adequate warning to consumers about its limited use. These are obsolete specifications and may cause harm in modern engines. The organometallic additive levels in this sample indicate the product is NOT suitable for use in the majority of automobile engines currently on the road.

Note: Although laboratory tests alone cannot be used to establish if engine oil meets an API Service Category, they can be used to determine if it doesn't.
