Reviews

"This is the only oil that I have found that does not cause me problems with my diesel exhaust filter. No regens since I have been running it. Ram 1500 ecodiesel."

Robert - Verified Buyer

"Run this in my generator for a peace of mind knowing it's the best"

"This exact oil saved a motor that blew a head gasket and lost all but 2 of the 14 quarts. Ford mechanic was amazed at how good the cylinders still looked. He stated he had many that had the same problems but all the others the motor was trash. Mine just had to have a new head gasket engine flush fresh oil and antifreeze. Then was back on the road."
