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.



Manufactured by: XPRESS LUBE PRO of Glenview, IL

Purchased at: Chicago, Il

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 59% lower than the minimum viscosity specification for this SAE grade. In addition, the Low-Temperature Cranking Viscosity is sufficiently low to indicate the sample should be labeled with a lower SAE W Grade than that listed on the product label. Furthermore, 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 metal analysis results for this sample indicate the product may be contaminated with engine coolant, and used oil, and abrasive material. Use of this product in modern automobile engines will likely cause harm to the engine.

 Note: The State of Missouri Weights, Measures and Consumer Protection Division ordered Xpress Lube Pro 5W-30, 10W-30, and 10W-40 off the shelves in the state. These products cannot be offered for sale in the state.

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.

  1. Standards, shown in yellow are established by API, SAE and others.
  2. Test Method for metal analysis is ASTM D5185.
  3. This specification is expressed to two significant figures, therefore results up to 15.5 are considered on specification.
