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.

Test Results and Assessment:

The Freeze Point test result for this sample exceeds the labeled claim. It should be noted, however, the freeze point is higher than the industry standard of -33.5⁰F required by many states. In addition, the chloride and sulfate levels are extremely high. Such concentrations can result in scale and/or corrosion. Furthermore, considering the product tested contains no Bitterant, it cannot be sold in the seventeen states that require a minimum Bitterant level of 30 parts per million(ppm).

It should also be noted that there are no ASTM, OEM or other industry specifications claimed on the product label.

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