Chrysler MS6395 ?

Hello all,
I was in NAPA the other day picking up one of their NAPA gold filters for my Patriot. They happened to be having a sale on their premium 5w-20 conventional (dino) oil at 2.35/qt so I picked up 5 qts. I was looking at the bottle and noticed that it doesn't mention the Chrysler MS 6395 oil spec on the fine print on the back. This surprised me as it's made by Ashland petroleum products who also make Valvoline oil.
My concern is if I use this oil (which is API rated SN by the way) would Jeep try to get out of any lubrication related engine repairs if any crop up during the Warranty period.
I seem to remember that there was some act passed by Congress that specified that a manufacturer had to honor a warranty as long as the right grade ie; API SN 5w-20 oil was used. But forcing them to legally comply with that could be more expensive than the repair!

Just for some background, I'm an old school "oil change every 3000 miles" kind of guy. I like the feeling of knowing that clean fresh detergent oil is in the engine. If using the NAPA oil could lead to hassles though, it might not be worth it.

What do you guys think about using NAPA conventional oil in this case?

Thank you for your opinions,
Robert

SN rated oil exceeds SM rated oil.It's the next generation rating that started with GM's Dexos oil.

You will be fine as SM rated oil is the min you can us and SN rated oil exceeds SM rated oil.

Chrysler is actually getting really picky about using oils that meet their oil spec. There have been reports of people using Mobil 1, which is no longer officially MS6395 certified( I bet it meets it though - it's a peeing contest between Chrysler and M1 as Chrysler swapped FF oil providers to SOPUS ), being hassled. I would only use an oil that shows MS6395 on the bottle or on the oil mfg's website( in this case Napa not Ashland/Valvoline - they are a little different ).

The law you are referring to is the Magnuson-Moss act. This does not exempt you from using the called for specs and ratings however. Chrysler can specify weight, API cert, their own spec, and even tell you when to change it by( time/mileage ). They just can not force you to use their brand oil/filter/parts unless they are provided free and they can't make you have the work done at a dealer.

The law also has wording about the auto mfg having to prove the thing you did( like a performance mod )caused the problem. This would not apply to Chrysler's MS6395 oil spec however. Either the oil meets it or it doesn't. You do not have to use an officially certified oil though. The owner's manual only states you must use an oil that MEETS the requirements of MS6395 not that it is officially certified. So as long as the oil mfg says it does you should be ok. If Chrysler hassled you and said it didn't then you have a claim against the oil mfg.

If you are truly worried use an oil that is on Chrysler's MS6395 certified list.

Oh, and seeing as you have a 2013 API SN is the oil standard you need to meet not SM.

NHPATRIOT x2.

There are a lot of oils that meet the spec do yourself a favor and run one of those while your under warranty. The likelihood of an oil related failure is slim to none, but why not take advantage of the coverage you have while you have it?

Thanks all for the replies.

Although I think the oil I already have would have been just fine, I think I'll put it aside to mix with some 15w-50 I have to use in my old "beater" Taurus.
I went out just now and picked up some Quaker State green bottle. It says Chrysler ms 6395 on the back label...

Like was mentioned I might as well not take chances on a warranty hassle.
