I run 5w30 in my 127k-mile '01 Durango's 4.7, no additives. Seems to work good, have only owned it since Jan though. Had a Fram filter when I got it, which I changed to a Microgard asap because I've never been a Fram guy. Only thing I noticed is that with using a Microgard filter, the timing chains rattle a few seconds longer on start-up than they did, so I'll be switching to a Wix next time as they are supposed to have much better anti-drainback valves. On start-up you can see the gauge come up to a 1/4 gauge, hover a few seconds, then go to 3/4 gauge almost. Once warm it has a half gauge of oil pressure at idle and 3/4 as soon as you touch the gas. A tech at the dealer said 5w30 was a good weight for it.
Although I know need to do the proper fix of replace the chains and tensioners asap. Just expensive to buy for this engine.
I have been using O'reilly brand full synthetic, been considering switching it over to Pennz Platinum, but after a little reading on here, kinda considering a good HM oil instead?
