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.

SAE 10W-30

Test Results and Assessment:

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 Kinematic Viscosity @ 100°C is lower than the minimum viscosity specification for this SAE grade. In addition, the labels state that this oil "Helps keep engines clean, provides wear protection, helps prevent engine leaks, and fights rust and corrosion". In fact, 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. Use of this product in modern automobile engines will likely cause harm to the engine.

 Note: The Bullseye motor oil brand has been ordered off the shelves in Alabama, Georgia, Michigan, and Missouri. This sample was purchased in Paxton, IL.
