PQIA Examines Five Deisel Motor Oil Samples

In response to a number of inquiries PQIA received over the past few months about heavy duty engine oils (HDEO), we took a look at HDEOs readily available on retails shelves. The results of the tests conducted on the first group of samples are consistent with their labeled claims. Click bottles below for details.

  1. Would like to see some of the off the shelf 5W40 HDEO which would be used during the winter months for cold weather climates.


  2. The Chevron Delo 400 XLE Synblend is also officially listed in the Mercedes Benz Bevo list for 228.31 Approval, but it doesn’t show it on the label.
