When they tore the first engine apart from the lifter issue the engine was like so clean in side all the techs could not believe it I guess depends on driving which mine is all highway miles so I like the RP.
going to give the PZ a try in due for a change now in a few weeks I change my oil every 10-12K

I'm not sure it's necessary however.
Considering the extra forces you are putting on the mains and the extra loads across the cam - I'd recommend it - other than maybe moving to a 10-30.

I want to keep the 5 because the bearing tolerances are still tight so I don't want to starve it any longer than necessary. I'd read that it's NOT a good idea to run a 10 on current engines for that reason. Back in the day when machining tolerances weren't as good, a 10W was necessary. This is why I went 5W40. I'll look for the Penn in it when I get there. Still a few months to go!

I can see where that might be true but I don't think a modern synthetic 10-30 has the same 0 degree pour points or shear viscosity of the older stuff. I'd have to check a spec sheet to be sure. so I mean that's always a good measure - check a spec sheet.
Then again with the dollars they also make a 0-40 or some such if it was really an issue.

Yeah I was there yesterday ..Purchased the last 5 quart they had left on the shelf near me.
Too bad (1) 5 quart doesn't do it. But I changed my oil with Penz Platinum before I put my G8 away this winter.
It cost me 58.00 bucks with an ACDelco UPF48R filter back in November.
