Schaeffer's SynShield OTR Plus Full Synthetic 5W-40 Oil (9000)

Best oil for a 6.0L

I’ve always used rotella in my truck. I’ve been having major stiction issues. Some people said I may need injectors soon. Last ditch effort I used shaeffers with archoil and it’s never run so quiet and smooth. After running a few hundred km the stiction is virtually gone, idles down quiet, and more responsive. I will only use this oil in my vehicles from now on. It’s a night and day difference. Shipping was quick and I like how they taped the lids and bagged the jugs in shipping.

Happy customer

So happy to find a supplier in Canada! A little far but great delivery service!
