XTREME 2000TM Super Premium SAE 10W-30 Motor Oil, API SF
MG Lube, Inc. New York, NY
Purchased in: Maple Shade US Gas, Maple Shade, NJ
Date of purchase: 6/2/2012
The labels for this product claim the oil is a 10W-30 motor oil meeting API SF. PQIA's test results for this sample show it is not a 10W-30. The analysis also shows lower levels of additives than would normally be expected for an SF engine oil. In addition, the product tested has a very high level of silicon which is commonly associated with abrasive contaminants.
Use of this oil could potentially cause damage in modern automobile engines.
Although the label on this product says "For all foreign and domestic cars," API SF is an obsolete specification that is not recommended for engines built after 1988. The label on this product fails to give adequate warning to consumers about its limited use.
