Okay so in experimenting with oils in my 4.0L Jeep with 80k & minor leaks, I am about to finish up an OCI with Pennzoil HM 10w30 in it. As compared to the Trop-artic I had in it before, it runs quieter & smoother and the leaks that sometimes could leave a dot on the concrete have stopped.
Next on deck waiting to go in is some Maxlife 10w30. I think most HM oils (including Pennzoil) have a decent amount of ZDDP in them when compared to normal oils. But Maxlife seems to be the exception to the rule and has lots of Moly but little if any ZDDP???
That being the case, does Valvoline know something the others don't or is it just that one additive costs less than another and that is how the select them?
I would want to use the HM oil that has the best additive pkg and I am wondering between the two additives, which is best & why?
thx
