I've found some info here on BITOG about Mystic 15W40 in both standard and syn blend but virtually nothing on the full synthetic HDEO with a CJ4 rating. Any experience out there? Price is real good at the local ranch store at $15.00 a gallon jug.
I'll use it in my 2017 Ram 2500 6.7 Cummins and I use it in several other applications including my Polaris quads. Thanks for the information. that's the price they sell it for all the time. Priced like the syn blend. I'm going to start using it!
