Antifreeze/Coolant 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.

Test Results and Assessment:

The results of the tests conducted on this sample are consistent with the labeled claims.

Note: Although the label on this product states it meets ASTM D-4340, it should be noted that ASTM D-4340 is not a specification. Instead, it is a standard test method for Corrosion of Cast Aluminum Alloys in Engine Coolants Under Heat-Rejecting Conditions. ASTM D-3306, also noted on the label, however, is a specification. This specification requires a specimen loss of <1.0 mg/cm2/wk when tested by ASTM D-4340. Coolant/antifreeze producers and marketers often refer to ASTM D-4340 because it is an important aluminum specific test method, and to ASTM D-3306 because it is a specification.

Note: Although laboratory tests alone cannot be used to establish if coolant meets standards, they can be used to determine if it doesn't.
