CONSUMER ALERT:
The label on this product states the oil "meets or exceeds car manufacturers' warranty requirements where an API Service SA/SB motor oil is recommended," In fact, NO car manufacturer's warranties recommend an SA or SB motor oil, and an oil cannot meet both of these service categories. 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, and the unusually high silicon level in this sample indicate the product may be contaminated with abrasive material.
