Claims to cling better and prevent internal rust and dry starts. No idea if it's a real benefit or snake oil, but it is a trusted brand. The engine builders on this forum can add their professional opinion on oil wt. and agree or disagree, but it is my understanding that unless you're tracking your car or driving it really hard a lot, a lighter wt. flows better and holds up fine. By the way, Joe Gibbs is now called Joe Gibbs Driven and eventually the Joe Gibbs name will be dropped.

This is also what Keith Craft provided me to initially use with my 428 based motor - Joe Gibbs 10W-30. So engine builders to at least some degree appear to think it's a good oil. I bought a couple more cases from Summit.
