Good oil.Had it before, but dropped after ingine start eating oil.Since bouthg different semi start using again.

Excellent oil!! Runs well on the 2003 6.0 powerstroke.

So, I started using this product in my fleet since the Supreme 9000 5W-40 CJ-4 is not recommended for newer EGR/SCR equipped vehicles. Two things Ive noticed: 1. The oil stays cleaner much longer 2. The buses use much less DEF. Because this is made by Schaeffers, I trust that the durability will hold up and keep my equipment running for many miles.

All good

On time great product thanks

Really good oil 5/5

I like that oil very much,(addicted to it) tried this oil in different cars, works perfect Ram 3500 Cummins 6.7, towing Goosneck, got 20000 miles of oil change. Mersedes ML350 Bluetec 15000 of oil changes, analyzing oil after 30 to 52 % life left.

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.

Best oil on the market it’s the only oil I’ve used in my medium and heavy duty trucks.
