Having my long time (40+ years) mechanic do first oil change at 3000k.
What list of oils can be used for warranty purposes?

2025 Ram 1500 Limited, stock
 
Anything with MS-6395 printed on the bottle, such as Pennzoil Platinum
 
Thanks for the great info. BUT I failed to note that I have the H/O.
Mopar calls for 0w-40, which, unless I missed it the info above didn't include a 0w- 40 branding.

not a 3.0 but the 5.7 calls for 10k oil changes so i go 5k do it myself then 5k and have it done so there is a record of it on carfax. if it;s under warranty and ya bought a kind of expensive HO truck i would just pay to have it done and not worry about what kind of oil to buy. that's just me.
 
Best oil money can buy IMHO (though... I'd probably go for a 5w-40 but don't if you're concerned about warranty)

Your owner's manual will have that information.

Ya I know, but it calls for mopar(of course) or equivalent.
I was just wondering what other brands ya'll are using.

In that case you want anything with MS-12633. If you can find Pennzoil Ultra Platinum 0w-40 it's a no brainer, they used to put (maybe still do) the SRT logo right on the front of the bottle

The MS spec is a nothing burger (and it's MS-A0921 for the HO). For warranty purposes you just need API SN+ or API SP.

PUP has no ability to clean, and it shears down to a 30 grade. There are far better oils available.

Let your longtime mechanic pick the oil, you have trusted him this long.
 
I'm not letting the ambulance driver do a kidney swap on me, just saying.
That is not the same at all, the mechanic is the doctor. You wouldn't let the porter pick your oil, you should let your mechanic do their job. If you have trusted them for 40 years,why question it now.

You doing your own kidney transplants now?

Easy there, it was a bad attempt at some humour.

But the point is that mechanics don't necessarily know squat about oil, no matter how much you can rely on them to fix your car. Most of them either read the owners manual and dutifully do as told, or even worse just dump in whatever bulk oil they have in their shop tank because "oil is oil".

I would say most independent, well respected, reputable shops take care of the clients and use quality parts/fluids that meet the specs of the manufacturer.

There are places that do use low quality parts/fluids, why would anyone use them? Because many people want cheap, they don't care about it.

I recently changed jobs, left Chrysler after 15 years. When I interviewed my potential employers, I spent a day there to see what they are about. What parts do they use, how do the employees get along, what their system is. What I'm getting at is, you as a consumer need to research who is working on your car, what they do/don't do, what fluids they use, and so on.

Of course. That's how I found HPL and why I absolutely ignore almost everything the owners manual says when it comes to oil and fluids.

And that's in contrast to your previous statement where you suggested to just trust the mechanic.

Your owners manual gives a base to start from. That oil meets the MS6395 standard, the one outlined in the owners manual.

MS-6395 is for the 3.6, 5.7 and SO, OP has the HO and as already mentioned above he would "need" MS-A0921.

The MS-xxxx is not a spec that matters in any way though.

The owners manual wants you to run "resource conserving" oil, which is a fancy way of saying they don't care about your engine health they just want you to run the thinnest ditch water they can get away with to eek out another fraction of an MPG (corporately).

One other fun fact from the owners manual, the ZF is lifetime fluid and doesn't need servicing, but ZF who builds it actually recommends like 60k mile intervals especially while towing. 🤷‍♂️

That isn't true, after attending a ZF training course put on by ZF. They stand by the manufacturer recommended maintenance schedules. They have to die to warranty reasons. Off the record is a different story....
