Schaeffer Manufacturing Co. 0700CK4-012 SynShield Durability Advantage 15W-40 Diesel Engine Oil, 12-Quart Bottle (Pack of 12)

This is the best oil by far.. Garantied to notice a difference..

Top of the line oil no doubt but, it’s advertised as 5 gallons but only contained 4.5 gallons. Where are the other 2qts I paid for?

Great oil truck starts better when cold

Top of the line oil for the Powerstroke.

I have a 2008 6.4 Powerstroke its some of the best oil that Ive ever used when I started using chafers Ive had the cleanest filters Ive had since Ive owned the truck I highly recommend this to anybody.

Amazing product I run it in everything!

Theirs no better oil on the market

excellent

AS A TECH I HAVE SEEN WHAT THIS OIL CAN DO TO A ENGINE AND I WILL NOT USE THIS OIL IN ANYTHING !

Good product from a reputable company
