2020 Ram 1500 Oil

[OVERKILL]

I wasn't nec

I wasn't necessarily recommending an 0W-20. Just specified the lightest weight oil that met MS-6395. I was more referring to the tendency to want to run a higher HTHS oil like a 40 grade vs a 20 grade. Yes quality control of lifters was (and possibly still is) suspect, yes the cylinder deactivation introduces additional stresses, valve float can play a role but yes a higher viscosity oil can contribute.

Again, I doubt it, or the SRT's, which use the same lifters and same MDS components would have MUCH higher failure rates, but it's quite the opposite. My dealer has never done lifters on an SRT for example.

Valve float can hammer the rollers and was a theory I mentioned in the other thread, but it may just be poor QC by the supplier, as GM experienced the same problem with their AFM engines.

Of all the brands that actually meet the MS spec, I'd use PP. PP is a very good oil.

That is the plan for now. My only gripe with PP is the additive fallout issue - not sure what to think of it. I usually like to stockpile oil when on sale but I may not be able to do so with PP.

They do.

As I stated early "Recommended for MS-6395" is listed on their site for Super Synthetic.

You would have to ask them why they don't list on other oils.

Just re-read your post. Got it.

Anyway, I think I will be staying with 5W-20 for the duration of the warranty and the extended warranty. Threads like these give me the impression that FCA is not particularly kind to DIY'ers and I do not want to give them any excuses for a denial:

When I owned a Ram I followed the same procedure I do now.

1. Photo or Fast Scan of Oil & Filter Receipts (With online backup)
2. Location & Time stamped photo of new oil and filter with the old filter and drain pan when changing (With online backup)
3. Paper Maintenance Log

Considering a Buddy still owns my 2000 Ram 1500 4x4 4.7 OHC with 240,000 mi and it never needed dealer service (5500-6000 mi OCI with PYB) under warranty I never got to see how my documentation would hold up.

 

[Audios]

Didnt read through all of the posts, 5 pages wow, but the parts manual recommends Mopar Conventional 5.20 Max Pro, so any of the choices youve listed would be more than acceptable.

Unless it's changed that is rebranded Pennzoil Yellow Bottle.

FCA responded to me this morning and advised the following:

"We recommend you use API Certified SAE 5W-20 Engine Oil, meeting the requirements of FCA Material Standard MS-6395 such as Mopar, Pennzoil, and Shell Helix.

According to available information, MS-6395 is a self-certifying process.

Additional information from FCA is either unavailable or considered proprietary.

You will need to contact the engine oil manufacturers for information regarding their claims and advertisement that they meet the requirements of MS-6395."

I think this may have been posted before but here is the requirements for MS-6395 in 2013, the last year I could find the document from.

So, layman’s terms: it’s acceptable oil for a HEMI

Looks like Mobil 1 would be if they followed the instructions from the document I supplied above, but Mobil doesn't claim it meets MS-6395.

1.4 Additional Requirements

Any oil marketer wishing to claim MS-6395 performance must send a letter to Chrysler with the form in Appendix A completely filled out (address included in Appendix A). Oil marketers must meet all the requirements contained in MS-6395 and may not claim conformance to selected portions only.

Well hopefully Pennzoil didn't appoint the person who posted the SP GF-6A Spec Sheets to write the letter. It would embarrassing if Mopar Oil didn't meet the requirements to claim MS-6395.

I have a 2000 Ram 1500 4x4 and a 4.7L was not an option for that year.

Just FYI We have seen multiple lifter failures in the SRT 6.4 hemis. So they definitely happen with those too.

Oh, I know it happens, we discussed this in the other extremely long thread about HEMI lifter failures, but the failure rate is roughly the same or lower than the on the 5.7L, not much higher, which it would be if the viscosity theory had merit. Heck, I found a few examples of them failing in the non-MDS Hellcat

 

[wpod]

Any oil that is from a major corporation and meets the specs.

 

[wpod]

recommends MS-6395. It just calls for API SN 5W-20.

People have a hard time. .

Have you considered starting a "my new truck thread" instead of 12 separate threads?

Worked for Buster and his new Nissan.

Higher viscosity can result in skidding which then results in flat spotting of the roller which eventually causes the needle bearings to fail which damages the cam.

God, I would like to see some proof of this. FYI, I'm running Mobil 1 FS 0W-40 in my 2016 RAM 1500 5.7 HEMI. Fuel mileage is great, the engine is quiet, 35 PSI oil pressure at idle with the oil at 220F. What's not to like?
