  • good brand
one of the few brand of oils that fit both specs for Cummins 6.7 in the 5th gen Rams. 20081 & 20086. Amazon has the best price, Highly recommend

  • Good stuff
I use in my 2020 Cummins X15. I do use an oil purification system on my truck. Change filters every 20k as well as oil samples. I ran 120k oblast oil change and even as the oil had 120k on it the oil sample came back good for viscosity, lubricating properties, and acid content. I did change oil at 120k just for my piece of mind but labs said I could probably get another year without issues. The lab shows 5/30 but is actually 10/30. ... show more
