I’ve always been on the thicker side, but I never understood people that run 15w40 and 20w50 when there are oils that have better startup characteristics than that glue. I know, they all say VII and sheer and blah blah, but I’ve never been a guy trying to stretch my OCI’s either. I just started running my engines to 7k OCIs since I run oils proven capable of that now. Why would I run 15w40 when I can run 0w40 or 5w40 that is superior? I also have a hard time believing people are interested in oil or performance if they run dino juice.
