also while talking to someone so familiar on engine maintnance, which oil thickness do you think would be proper to run on my 155,000 mile 5.2? Thanks alot!
Well I am at 123K miles and I run Valvoline 10W30 and have oil pressure cold at 80 PSI, but it differs from the user so for you I would just bump up to W40 which would be typical from any mechanic. So yea either 5W40 or 10W40 would be fine. As another TIP I like Fram but stay away from them because they do leak a little at least for me I have experienced this problem, so just pull down for 6 bucks and buy a genuine Mopar filter. You can get them at the local advanced auto parts store. Always put some oil in the filter and finger some oil on the oil filter gasket before installing.
I run 30 Grade because their hasn't been much wear on my engine and it's pretty much spotless clean and the mileage is highway mileage so their hasn't been to much wear on the rod bearings.
