The Petroleum Quality Institute of America (PQIA) is an independent resource for information and insights on the quality of lubricants in the marketplace. Our mission is to serve the consumer of lubricants by randomly sampling and independently testing lubricants taken from the field. Test results are posted along with the brand names on the PQIA website. This webpage provides an analysis on the brand detailed below.
The following are the test results for the sample examined.
Marketed by: TruStar Products in Roseland, LA

CONSUMER ALERT:
The results of the tests conducted on this sample do NOT meet the SAE J300 specifications for the SAE Viscosity Grade listed on the product label.
The label on this product states "Recommended for Pre-1988 Gasoline and Diesel Engines Requiring SC/CC Motor Oil". The only gasoline engines requiring API SC motor oils are actually pre-1967, and diesel engines requiring API CC motor oils are pre-1990. These are obsolete specifications and may cause harm in modern engines. The label on this product fails to give adequate warning to consumers about its limited use. 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 indicates the product may be contaminated with abrasive material.
Furthermore, the viscosity grade is misstated on the labels and should be shown as SAE 10W-40. The labels show 10-40 which has no meaning.
NOTE: TruStar in various viscosity grades has been ordered off the shelves by State Authorities in Missouri and New Jersey.
