Cam2 is a quality oil, I use their Semi Syn 5/30 as my cheapie oil, and was recommended to safely run to 8k on both a Ram 1500 and a BMW 325i by Blackstone.
Always thought they were formulators/blenders like Amsoil (buying base stocks from a refinery) but with racing background and interests … Now more mainstream?
Not oil consumption in a 5k interval. When I went 10k, I noticed I lost some. I've used Cam2 Blue Blood European in my BMW for up to 10K...good results.
