The independent resource for information and insights on the quality and integrity of lubricants in the marketplace.


PQIA reports test results on four brands of motor oils in various viscosity grades available on retail shelves. The products were purchased in Pennsylvania, North and South Carolina, and New Jersey.
The results of the tests conducted on these samples meet the SAE J300 specifications for the SAE Viscosity Grades listed on the product labels, and are consistent with the listed API Service Categories.

  1. Hello Tom
    Checking StarFire 5W 20 against Chevron 10W 40 listed,(5W-20), I Find Much better technical specs for StarFire over Chevron,since it is a synthetic as expected,but always cannot compare value unless you publish what retail price was on each product. I am aware that you do not compare cost comparisons,but full value of your work never completely shows any reason why one is better than another for your reader to achieve full value of your info.
    You are aware that there is a radical variance in so-called synthetics,and I feel that your work will have more efficacy ,over and above whether or not a lube meets it’s spec.,without comparing these technical specification that you do publish,for each =; Example: A PAO ,TBN spec would be in the 10-12 range,the StarFire was in 8 range,as a synthetic,Chevron in the 6 range—So what level of synthetic can a non-educated consumer presume on a given spec,as opposed to the varying “Synthetic” label,on any/all products,so labeled.
    Is this Not in your purview as a researcher/verifier of quality ,as it appears to me ,that “quality”, IS determined by cost/value ,as an integral part,of cheaper/costlier products,based on the reported compliance or non-compliance factor that you so diligently present to the Entire Industry for consumer protection.
    Thanks for your diligence and commitment,and Happy New Year to you and yours.

    • Big Al B-

      Thank you for your comments and your concerns for oil quality. We understand and appreciate your points about cost and value. Please keep in mind, however, that PQIA’s mission is to educate and serve consumers of lubricants by monitoring and reporting on the quality and integrity of lubricants in the marketplace, not to determine value or compare products.

      PQIA’s sample analysis program is intended to help assure that the products tested are consistent with labeled claims. It is not our intention to differentiate degrees of performance among oils and make value judgments since we do not conduct all specification tests. Further, we do not report prices since prices can vary widely from store-to-store and from location-to-location and may not necessarily have a bearing on quality and/or lubricant performance.

      Happy New Year to you too.
