Results for a Third Group of CK-4s are in
In addition to PQIA’s ongoing effort to provide consumers with information about the quality of lubricants in the market, we present our readers with information and insights about trends and changes in the industry that can sometimes be seen in the data from the samples PQIA examines. Recently, as an example, we reported preliminary trends for passenger car engine oils as we moved from API SN to API SN Plus (see “Get ready for SN Plus“). The PQIA will provide a similar analysis of the data and trends for the new CK-4 heavy duty engine oils (HDEO) as we build on the number of samples in the PQIA database.
The results of a third group of HDEO brands are now in. The data and assessments for these brands can be seen by clicking on the images of the products below. The test results for each of these brands all meet the SAE J300 specifications for the SAE Viscosity Grade listed on the product labels, and are consistent with the listed API Service Categories.

Mining the Minds in the Lubricants Industry
The Petroleum Quality Institute of America receives emails and phone calls nearly every day from consumers, marketers, blenders, and a number of others with questions about lubricant quality, performance, and other lubricant related issues on their minds. Whereas PQIA makes every effort to answer these questions, we take a pass on some because they are either outside the scope of PQIA’s mission or beyond our domain expertise. Understanding, however, that some of the questions are asked quite frequently, PQIA thought it would be of value to put them out to the industry for consideration. The following question, capturing the comments of others we hear from, is the first of this type and we welcome hearing from knowledgeable industry members about their thoughts on the question below. Let us know what you think
On the Minds of the Consumer
