I’ve been running schaeffer’s in my trucks and equipment for the last 8-9 yrs. Always great products, haven’t had an oil related failure since. My duramax is pushing 330k!

I’ll drive a 7.3 diesel and I’ve always run Schaeffers in it and hope it pays off in the long run. Only thing negative is it’s too expensive

I first encountered Schaeffer oils at a local tractor dealership. They were recommending Schaeffer Racing Oil for use in engines in garden equipment. I started using that oil in a 1942 Chevrolet and noticed a quieter engine and improved oil pressure. Began using Schaeffer 15/40 Diesel oil in my Cummins 6bt boat engine. By the dash gauge, the oil pressure in that engine improved slightly. Engine runs smooth and cool. Very satisfied with Schaeffer oils in both automotive and marine applications.

Well I have been using schaeffers oil since I bought my pickup back in 2006. It had been good to my truck for years and here we are goin over 100,000 miles and keeps working just great. I have no complaints about the oil.

Been using schaefers grease for a while now, finally gave their 15-40 oil a try.. a little on the expensive side, but should be worth it.

I'm a pipeliner. I always run Shaeffers oil in my trucks. Purchased this truck new in September 2019. Currently has 83000 miles on it and runs great thanks to your product.
