My uneducated observation is that your iron likes to show itself since you switched to T5. Your iron doubled in half the OCI.

Has there been any other changes, such as duty cycle, filter choice, or usage since then around that time?

Looks good. I see the magnesium is still there, and you had plenty reserve TBN.

No real change on the T5 run. Although she was running a tad warm on I-5 in Cali on that run pulling a cargo trailer from Georgia to Cali to Alaska. Mainly used Baldwin filters until recently I experimented with a Wix XP on the previous run and a Fram Ultra on this UOA.

Not a bad run. Within normal wear expectations. That's the good news. But, it's a Dmax; "normal" is normal - that's what we expect. What we see here is totally within "normalcy".
I realize this is your UOA in your thread, but I offer this for consideration ...


https://bobistheoilguy.com/forums/ubbthreads.php/topics/4527295#Post4527295
As you can see, I am getting slightly lower wear than you, when Fe wear-rate is averaged.
In contrast, I run dino Rotella 10w-30. All while flogging my 2006 Dmax in heavy towing this last UOA. I assure you you're not running your rig any harder than I did in my last UOA; I was running at/near max EGTs for most all the trip, fighting headwinds pulling my RV for hours on end.


Are you getting "better" results using an expensive syn?
It depends on how you define "better" ....

- You certainly are not getting less wear, that's for sure.
(your last three Mobil syn oil UOAs have given you 3ppm/1k mi, 4ppm/1k mi, 4ppm/1k mi)
(my last four Rotella dino UOAs have given me 2ppm/1k mi, 2ppm/1k mi, 2ppm/1k mi, 3ppm/1k mi)
- You certainly don't need a syn for "cold" starts in most areas.
(these are HPCR injection, with intake grid heaters and glow plugs; starting generally isn't an issue if your batteries are in good shape. My Dmax has started as low as -17F, on dino 10w-30)


You're probably spending 3x more money than I am; what is 3x "better" in your UOAs?

The Dmax engines simply don't care what is in the crankcase, as long as it's an appropriate lube. Base stocks don't matter. Vis does not matter. Brand does not matter. Your UOAs, and others, and mine, just continue to convince me that the Dmax is one of the best wearing light-duty engines made. And they don't need anything special to return excellent results. Syns have not shown any statistical advantage of wear reduction in a Dmax. The lube system design of the Dmax is what controls wear rates; not the base stock or brand of oil.

Yes- this is a challenge to you. It's not meant to be a taunt, but a friendly challenge for you to think outside the synthetic box.

The act of preventative maintenance, in and of itself, is FAR MORE important than brand/grade/base choices among lubes and filters.
- under maintaining something is akin to abuse/neglect; that can kill equipment by shortening the lifespan
- over maintaining something has never been proven to be anything but a waste of time and money

You seem to have had a winner with the Rotella T6 when you went 21k miles and only had 24 ppm of Fe. That seems so good, maybe it was an error at the lab. I think you should do another OCI with RT6.

I'm jealous of your oil consumption. I wish my diesel was that good.

DN3, valid statement on the lack of ROI with synthetics in my application. This is my wifes daily driver and she does jack rabbit starts in the morning, 13..0x sec 1/4 mile times on occasion, and does not let the turbo cool before shutting her down after a hard pull. I guess the synthetics just give me peace of mind so I sleep well at night. I dont think I would run synthetics if I wasnt continuously finding it on sale for $10/gal or less. I have 2.5 gals of T5 in 10w-30 and 15w-40. I will likely run one of these in my next OCI.

Can someone prove that the metals found in used oil are from engine wear?
