I've been using Mobil Clean 5000 lately, and I really seem to like the performance, not that it is any better or worse than another oil out there. I’m not comparing. But wondered if anyone else out there is using it and liking it? I won't keep it in my car longer than 3-4 months or 3k anyway. I will note this observation I've had compared to other oils. I checked the level on the stick after running it for 500 miles and strangely, it appears to have a much more yellow tint to it when I wipe it on a white paper towel, whereas the other brands of dino seem to brown or darken more. Anyone else notice this about the Mobil Clean 5000?
