Her are some reviews from real customers:
Fast shipping, good communication - and the best oil! Schaeffer’s is the best oil, I won’t put anything else in my powerstroke. Dan K.
The only oil I use. Had a friend who was in the chemistry end of the oil business and recommended Schaeffer oil along with a couple of others. I went with the Schaeffer oil first off and I’m pleased with the results in my 2017 Ram 2500 diesel. Running 20,000 miles with a Donaldson filter with no oil added during that time. I’ll be going with the molly additive next oil change as well. Dale B.
