Schaeffer Product Recommendations For 6.0 Powerstroke Diesel

Buy1oils Recommendations For PowerStroke Diesel

Customer question:

I have a PowerStroke diesel which of your oils and fuel additives would you recommend? Thanks!


We recommend using either the Synshield Durability Advantage CK-4 15W-40 which meets the new Ford WSS-M2C171-E specification, or the Supreme 9000 Full Synthetic CJ-4 5W-40 for all of the Ford PowerStroke engines.

Please keep in mind Schaeffer oil does such a good job cleaning we recommend not doing an oil analysis during the first change but only after the second change. The first change will result in breaking free any suspending wear metals that are present in oil gunk deposits that are the result of running lower quality engine oils. This results in a high wear metals result which can be very alarming to some but is entirely normal.

In addition we recommend using Schaeffer's 137 Diesel Treat 2000 which is available in Summer and winter blend 137ULSW. There is an extreme winter blend 300ULSW. All pictured below are available for purchase online at
