The Petroleum Quality Institute of America (PQIA)

The Petroleum Quality Institute of America selects and tests 5 to 10 brands of lubricants a month. Samples are selected randomly by region, and the oils tested to date are summarized below. To see the full analysis for each oil, just click the bottle picture below. 

 

Many oil manufacturers are proud of the quality of their products and are anxious to have their oils sampled, tested, and published by PQIA without waiting for their oil to be selected randomly.  To assure all manufacturers have an opportunity to have their brands tested and results posted on this website, PQIA will test any specific oil upon request by the oil's manufacturer provided the manufacturer pays for the sample collection, testing, and administrative costs. As with all oils tested by PQIA, samples will be collected from the field by PQIA, independently tested,  and all results will be published here without influence from the manufacturer of the brand, PQIA Supporters , or any other industry party.

 

Please contact us at testmybrand@pqiamerica.com for more information on how to arrange to have your company's brand(s) sampled and tested, and results posted on this website. 

Test results shown at the links below are specific to the packaged lubricants purchased by PQIA at one location on a given day. As such, the test data for the brands shown should not be extended to other types and grades of the same brands, or the same types and grades purchased at other locations. Instead, these data only provide a snapshot of the particular sample.
