I've been using Chevron Supreme 5w30 API SN for a few years. I'd pick it up by the case from Costco and have been happy with it in my 94 Ford van, 351 Windsor, 276,000 mi.
I just picked up a case from Walmart and saw that it is now, API SN Plus. Are the changes in formulation significant? I know that the change was for use in turbocharged applications. Should I just stick with it, like I always have, or shop for a different dino oil?
