I’ve been running Rotella in my personal and fleet trucks for quite some time now. Just got delivery of my new Ram 3500 limited(comes from factory with T5 rotella)…or so I’m told. Fast forward 2 weeks I put 2k miles on her and that’s right around the time I do my first oil change on all my diesels. I decided to grab this stuff on a recommendation from a good friend, didn’t expect nothin much of it as a difference from rotella. Boy oh boy was I wrong. Right after driving off from said oil change I could easily feel and hear the engine performing differently in a good way obviously, fast forward a few days and I went from 13.4 mpg to almost 16. Did not change a dam thing other than oil. Still driving the same if not faster. From now on all my trucks are running this oil.

Excellent quality oil. I use this in an old 3800 GM v6 and it works quite well. Although not fully synthetic, if you do your research, this is much better than even full synthetic Castrol. Pour point, viscosity index, and flashpoint are very impressive. Moly enhancement really works, probably better than Royal Purple which is another moly enhanced oil.

Good oil at a great price, well worth the investment as I plan on driving the tires off this thing.
I was previously running Castrol Full Syn and switch. My idle oil pressure is now 10 PSI higher. I tested this on a brand new oil pump and used Castrol after replacement. Used Sheaffer on the next oil change and I am happy to see the oil pressure running hire..

I’ve been a professional auto mechanic for 35 years. the best oil I’ve ever used.

This stuff is in fact.. the cats MEOW!! I would only recommend this formula for cooler climates before running it myself, but it in fact holds its own in severe heat as well! It holds slightly more oil pressure than Rotella 10W-40 at the same temperature! I’m pleased! I’m running this in everything I own now!

I’ve put 110k miles on my truck over the last three yrs and finally switched to Schaefer’s. She’s instantly running more smoothly than I remember before the wear and tear. Impressive stuff. Should’ve started using it BEFORE all those miles but this has definitely made a notable improvement.

I use this oil in a 2007 F-350 SRW 6.0 bulletproofed powerstroke and also a 2020 Ford F-450 6.7. It meets the Ford spec and it’s one of the best oils in a Ford diesel. I have analysis and used delvac, rotella, delo and Amsoil. Best mpg, best wear protection. In 8k miles in a 6.0, total of 9ppm for iron and 3 for copper.
