Found some Pennzoil 15W40 but I have a question...

The local Advance had several quarts of this but in different bottles - I looked at the backs and some were SJ-spec and others were SL-spec... Any reason I should prefer one over the other, or are they basically equal oils?

Were both of them CI-4?

I'm almost certain they both were, but I'd have to look again to be sure. Seems like the SL/SJ was the only difference.
