Although, with my vehicle warranty (lifetime powertrain), Chrysler specifies oils that meet MS-6395. If there is not a High Mileage oil that does not specfically meet MS-6395 I would just stick with a convential that does.
Since my vehicle has a LT powertrain warranty why would consider spending more for High Mileage oil if it's not necessary? Because I like the feeling of giving my cars the best reasonalble maintenance I can.
FWIW as they say, my Chrysler 98 minivan(that takes not so mini 4x8 sheets inside) 3.8 has 211k and I use 5w30, trop artic from a few years ago stash, right now. The drivetrain hasn't been repaired, yet, and it runs very well, although now I hardly use it, just to haul things. I'm going to go risky and try 10w30 synthetic from Walmart next year.
I was wondering about that warranty, seems they no longer offer it? I think if the dealer charge is reasonable I would take mine there if I had that kind of warranty, get the book stamped, and forget about the oil advertising hype, IMO.
