Calcium and magnesium in the formulation changed in '18. Was it possibly a different oil specification? .

Depending on the stock he used it could have been the change from CJ4 to CK4.

Hopefully....they won’t balk at you with those two (1) year interval oil changes.

I'm sure Amsoil will step up and own their guarantee.

CJ has been down the road for a bit. Possible, though. If 12v wants me to ask I could forward it to my old office and ask the CLS his thoughts. This youngster is about as geeked out on this stuff as one can get. Just try not to take up his time if I don't have to.

I'm sure Amsoil will step up and own their guarantee.

That’s the right timing for CJ going away.

I made the switch from CI-4 to CK-4 (the exact oil Ron is running) on my 2005 in the fall of 2018 because the formula changed for CK-4.

 

[JR]

Ck4 rolled out 2017. Ron changed late 2017 for the sample that shows 2018. Thats right in line with the changeover.

I am near warranty end of this month. I will take all this info to the dealer. My Son and his friend that have a 15 and 16 HO both say my engine does not sound right. I know their Mechanic and will talk to him first!

I kinda doubt a dealer will put much stock in your reports. They are not going to open the engine up looking for a smoking gun. If you can't pinpoint an issue/complaint for them to check....With warranty ending soon they will figure you are grasping at straws....not trying to be negative, but....

It's the 45 year old "AMZ/OIL" you've been running.

HMMMM, don't think AMZ/OIL had anything to do with this.

I understand but since this seems to be related to an issue with air filtration maybe they can fix whatever that is. I will be asking lots of questions when I speak to the Diesel mechanic.

How would that cause my silicon number jumping so much in the 2019 sample over the 18 sample then stay high after that?

Not silicone, but other differences. DME was reformulated for CK. If you call them they be able to tell you how.

Not trying to be craas, but Taking your air inlet piping apart every oil change could well be the culprit more than anything. Unless there is a hole in the piping or a broken clamp, etc.
A big reason industrial equipment run filter minders is, they do not want you opening the filter for inspection and risk contaminating the clean side. Their stance is leave it alone until the filter minder says otherwise.

My comment was in response to GS comment about running 12 month oil change intervals, not anything specifically to do with your UOA.

Not sure about the RAM trucks, but I've heard from some that the air cleaner seals take a "set" and once should try to avoid opening / closing the air box to prevent leaks on the clean side from gasket deformation, I've had mine off once in 20k miles but it was due to the underboost code I had in WY (was faulty EGR valve FYI) and I wanted to check for a restriction whilst on the road, otherwise I do not mess with it until the interval comes.

 

[Cummins12V98]

Really don't see what removing the air intake has to do with it. Looks like I forgot to tighten the lower clamp this last change but everything still looked good and filter was doing it's job as shown below. T

hat's 15k use.

Just assumed you were messing with me.

Every 15k I changed my air filter and the first four samples were great. On every 12V or 24V I have owned the air intake came off to access the oil filter with excellent reports.

Truck is a Pavement Princess so it's fairly clean in the engine compartment.

OK, since my air intake looks good what else could cause the silicon to have jumped.

 

[AH64ID]

Lower hose is post filter, it could easily suck air thru a loose lower clamps and into the engine without dirtying the intake. It doesn’t take much to show on the UOA.

There aren't many sources for silicon hence my comment on removing air intake piping. It takes a surprisingly small amount of dirt to show in a UOA. Major filter manufacturers like Donaldson and Fleetgaurd have a pretty firm stance on "over servicing" of filters and if you are swapping yours out every oil change, much less disturbing other connections I'd wager you fall into that category. We live in very different climates but my air filters get changed every 3-4 oil changes. I've personally only changed 2 filters through almost 100k miles of use. Again, very different climate but my silicon levels have never come close to that of yours (9ppm max across 4 UOA).

Aside from the obvious (dirt ingestion). According to Schaeffer's, where I get my UOA, Silicone gasket maker, coolant additives, and anti foaming agents are the next big contributors of silicon in a UOA. You can easily account for or eliminate those sources.

There is a time for jokes, and not. I totally understand the concern. These are our babies!
