What are you using it in? Have you checked all the specs to make sure it meets manufacturer specs beyond the CJ4 classification? My 2017 Ram specs ROTELLA T6 FULL SYNTHETIC 5W40, meeting whatever the MOPAR spec is in addition to the CJ/CK4, and they're pretty picky about it and will sample the oil if there's an engine failure. I'm sticking to their requirements and MOPAR filters until the warranty is up.
I've never heard of the brand & There doesn't appear to be any specs or information on the drum itself. It's priced like a high quality oil but ...........................
