This Is What I Have

I have a bunch of Rotella T6 15 w 40 and a NAPA Gold 1495 filter. I usually put the Rotella in my Dodge diesel but switched to a new oil called Schaefer’s. I would like to use the Rotella in my Cherokee. Will the higher weight oil hurt my motor?
I live in Atlanta, Georgia and it is about to be summer here. HOT 🥵

yeah... 4 years going and works just fine...... if you're in the southern climate like me... no worries. And the extra ZDDP is good for the ole flat tappet 4.0 too.
