Oil preference and filter

Must be a busy week at the oil analysis lab. Tracking shows they recieved it. Will keep checking.
Thanks for checking. I'm following this closely, been using Redline for the last few changes but would love to see if Schaeffer is even better (and "properly" donuted!)
 
I was going to use Amsoil for my 23 TRX, so I asked Amsoil if their oil met the new MS-A0921 specification for the '23's. I got this reply:

"Thank you for your email.

Currently, the AMSOIL Signature Series 0W-40 does not meet the MS-A0921 specification. We currently do not have any engine oil to recommend for this model year Ram engine.

We hope this is helpful."

Based on this, I won't be using their oil. I don't want any warranty headaches.
Amsoil Signature Series 0W-40 does meet MS-A0921 specification now. this was from a task that got sent to Amsoil dealers on 10-13-23. Amsoil also has an OE 0W-40 but that one is not recommended to be used with the 6.2L engines.

AMSOIL Signature Series 0W-40 (AZF) is now recommended for applications that call for the Chrysler MS-A0921 specification. This specification covers many newer Dodge SRT street-performance vehicles like the Challenger and Charger SRT equipped with the 6.2L Hellcat engine as well as Ram TRX (6.2L) and HD models such as the 2500 and 3500 series trucks equipped with the 6.4L Hemi.

Now Available: AMSOIL OE 0W-40 100% Synthetic Motor Oil
March 1, 2024
AMSOIL OE 0W-40 100% Synthetic Motor Oil (OEG) is now available.
The new OE viscosity is primarily for 6.4L Hemi engines in newer RAM three-quarter-ton pickups and larger heavy-duty fleet rucks. Common uses of these trucks include towing/hauling, camping, construction, lawn & land work and hotshot trucking. OE 0W-40 is API certified for fleet owners who are more price sensitive yet want a step up in protection.
Owners of Mopar performance vehicles equipped with the 6.2L are not the intended customer for this product. These vehicles are typically owned by enthusiasts who seek the best, regardless of cost. Signature Series 0W-40 100% Synthetic Motor Oil (AZF) will remain the primary recommendation for these vehicles.

If I don't get word this week, I'll call them to see when the results are going to be available.

Did you use blackstone? They received mine February 21st. Still no word from them...

Just playing devils advocate here because I would still use Amsoil SS over any API oil. But it’s worth noting that the SS doesn’t even have API certification, so being “recommended” for applications calling for the Mopar material standard is irrelevant. By the book, an oil meeting their material standard isn’t actually required, but an API certification is.

Also worth noting that Amsoil OE is API certified, and it’s actually a poorer performing oil all around. Just kinda interesting, isn’t it?

It looks like the 0W-40 SS AZF oil is an API certified oil.

You cut off the important lawyer-induced word salad before that part. “Use in applications that require API SP…” is not the same as API certified SP. Same goes for all the licenses they list. They sure aren’t buying all of those on that list, and they wouldn’t qualify for any of them anyway since it’s not API.

Contrast that with the marketing page of the Amsoil OE:

And how bout that starburst on the bottle, they couldn’t make it any bigger:

Amsoil SS is over-added to meet the API specs, always has been. Hopefully always will be because it’s better for it.
 
Here’s a list of all the Amsoil oils that are actually licensed. SS ain’t one.

So how does there OE 0-40 compared to other api certified oils you think?
 
The OE 0W-40 doesn't have the donut.

The OE 0w40 is a new product so perhaps it was still pending certification when they did the artwork. Best guess I have. Nevertheless it’s on the current list from the API that I posted so it’s good to go as far as warranty.

As far as product quality it’s on their lowest end. Really no better than a SuperTech synthetic or similar shelf oil. Pending results from @SCARd4Life the Schaeffer 9000 seems like the best API oil for these trucks at this point. It’s the only one I’ve seen that’s majority PAO instead of Group III. Add pack will still be limited vs an SS or Red Line but at least the base stock could approach boutique quality. Unfortunately the price does too so for my money I’ll stick with Red Line.

Where are you getting your Redline?! I'm seeing $168 for 12 quarts of Redline 0W-40, and $162.65 for 12 quarts of Schaeffer 0W-40 directly from Schaeffer.

Let’s say I’m using Amsoil SS or Redline on a stock engine and have a failure. What do you think the likelihood is of Ram trying to deny coverage based on that? Seems like it would be fairly easy to show that wasn’t the cause considering those oils are vastly superior to PUP.
 
Just thought I would throw in my 2 cents into this whole conversation. I personally have been using Pennzoil in all my vehicles for the past 14 years or so and has worked well for me. Here is a video that I have found comparing Pennzoil vs Amsoil. I think this guy does a pretty good job with his testing. Plus all his other videos are always interesting to watch. Enjoy...

I got my last batch here:


Came quick and shipping is free if you get two cases.

(In the last post I was just saying both oils share a similar “boutique” price point but one’s additive pack is still somewhat constrained by an API certification).

Not enough for me to worry about, that’s for sure. I haven’t had an API licensed oil in this truck in two years. I’ve sampled every oil change (except the break in). I started with Red Line, went back to Pennzoil to use up what I had, and then Red Line again. HPL Super Car also got a test run but the Red Line performed better.

Ironically through all of this the worst samples I took were with the Pennzoil by far, it dropped out of grade both times and wear metals spiked. So yeah, not gonna worry about using Red Line or Amsoil or anything else after those results.

Could this be why it doesn't have the donut?

If anyone is interested. I was using penzoil ultra 0w40 switced to redline 0w40. This is the oil analysis of both.

If I'm reading that correctly, the Redline was better in 7 of 16 categories. 4 were a tie and the rest, PUP had better numbers than Redline. Clearly Redline is much better than PUP in the viscosity test.

Changing my oil every 6 months, I will rack up about 2,000 miles. I'm thinking at that low of a mileage interval, the PUP viscosity drop won't be nearly as bad.

Good catch, yes and no. It can actually still have the donut, just not the “resource conserving” text (no xW40 can). Also, the starburst only goes on ILSAC grades (20&30), so my mistake on that. My lines got crossed between the donuts and the starbursts we were talking about.

There was probably a lot more fuel in that Pennzoil sample than Blackstone was indicating because that viscosity was sick. It does have a tendency to shear but that remains the worst I’ve seen. In my own truck after ~1700 miles it was 11.2 cst. Still too low for my liking but not SAE 20 low like that one.

Yeah, 11.2 cSt isn't too far out of the normal range. I'm looking forward to the test results for the 0W-40 Shaeffer's oil from @SCARd4Life. Fortunately, I'm not in a big hurry.
