Has anyone done Used Oil Annalysis (UOA) for their Hemi 5.7? Can ya post some up here for me. I'll probly do one next fall and post it up but I'd like to see a few posted to give me an idea of mileage, oil type and weight, etc.
Haven't done one myself, but I know several people that do them regularly on thier cars. They are worth it if you want to know what kind of wear you have on the internals, as well saving money on oil changes, especially if you use a high quality synthetic like Amsoil.
i change my oil evert 6000 to 6500 miles using penzoil ultra, so i will never have one done. if i have to crawl under the track to get the oil to send away for uoa, i might just as well change it. coming from the era of 3000 mile oil changes, i just don't see myself going much longer between oil changes, ever.
I've done one for each of my vehicles in the past. I just would like a starting point on the Hemi since I've never owned one. I know the sump is over 7 quarts so it should go a while before it needs changing. I change my own oil and that is when I take a sample. I don't take it without changing it. Gonna change out the dealers oil in the spring (don't know what they put in it) and replace it with Penns. Platnum 5-30 synthetic. I know it says 5-20 but I don't have the MDS in the 2500 so no worries there. 5-20 and 5-30 are real close anyway and that is what I have on hand so in it will go. I'm a regular on boboistheoilguy.com and have looked at UOAs for the hemi but would like to hear what U guys have done.
