Schaeffer oil here. I'm on their oil sampling program and have proved to myself I can run on a premium oil longer with out it tapping out. Most guys that say this or that is good oil really need to start sampling. before I retired, from farming, I was running Scheaefer in my Volvo Detroit powered semi, was able to double my change intervals with no issues whatsoever. Like E85, my cost per mile was the least expensive running schaefers. |
