Petroleum Quality Institute of America

PETROLEUM QUALITY INSTITUTE OF AMERICA TEST PROGRAM

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.

EXPRESS LUBE PRO 10W-30
No API Service Categories or other approvals specificed on the labels

Xpress Lube Pro 10W-30

Manufactured by: Xpress Lube Pro

Physical Address: Non found

Purchased at: Chicago, IL

Date of purchase: 12-4-2014

Test Results and Assessment:

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 Kinematic Viscosity @ 100°C is 26% less than the minimum viscosity specification for this SAE grade, and the Low-Temperature Cranking Viscosity is 22% higher than the maximum viscosity specification for this SAE grade. 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. The metal analysis results for this sample indicate the product may be contaminated with used oil. Use of this product in modern automobile engines will likely cause harm to the engine.
