Just spotted this one at Walmart...I like the idea of Synthetic, but I really want to keep the additive package that we all know the 103+104 valvetrains enjoy.

It meets CJ4 specs...and is heavy duty..
It says comparable to the 15-40 on the back of it...
I wonder if it's got the same additive package as the 15-40 conventional?

What do you guys think?

Not worried about leaks, I'm good. Engine is spotless.
