This is a Durango that gets 40 to 50K a year in over the road use. This engine seems to beat the oil to death before the magic 15K number Amsoil claims the oil will go in severe service intervals. I have been an advocate of oil analysis and these numbers tell why. Engine has worn well and has been using Amsoil most the life of it with an Eao oil filter. Oil viscosity just can't stay in 30w grade. Numbers are from left to right about every 11 to 12 K with one 14 K run....you guess which one

Where is the real/full report?

Amsoil.com says "up to 15K".... meaning it could be less than 15K for severe use.

Some of your wear may be coming from your air filter choice and/or air filter box's possible intake leak.
 
If you Google "durango sludge" you will see there are some very unhappy owners with some terrible problems. You might want to consider an Auto-Rx treatment and changing that Amsoil a bit more frequently. You have shown enough info to make me think you are no easily alarmed by a less than average uoa. Posting here is a positive step. As Pablo requests, were is the rest of the data?
 
LargeCarManX2,
Did the owner ever try the Series 3000, as I suggested the last time you posted a UOA?

Though I thought the sludge issue was resolved as Pablo stated, it could be a problem for this engine as well.

I would say try a cheap oil for 3,000 miles and do a UOA just to see how it compares to the Amsoil numbers.
 
You left out the date and other data. Was this the SM stuff because if that last row is the 14,000 miles sample, the viscosity is much improved compared to the last 3 samples.

ASL start 10.5 cSt
12.4 cSt after 14,000.

Only went up 2 cSt over 15,000 max on this oil.

I would also consider RLI in this engine.

That sucks. I thought it ended in 2004, but searching the 'net says otherwise:

I don`t know,the link for car complaints quotes an owner of a 4.7,"The heads have sludge but the pan had none. Which is consistent with plenum gasket failure". Does the 4.7 even have a plenum gasket like the 5.9`s??

Anyway my 03 Dakota is purring away nicely with 90,000 miles and a co worker has an 00 with 240,000 miles with the same power train,4.7,45rfe auto.

Howdy, No, he did not want to spend the money on the series 3000 and is happy with 12K changes. I don't think sludge is a problem with his engine. The oil is just past the 30w into the 40w territory. I don't think I can talk him into dino or 3K or any other oil....he's happy! He is over the 100K mark now and every 12-13K he is just going to do the Amsoil and Eao OCI. The 14K run showed us the oil just pooped out with this 4.7 L engine. He does easy over the road miles...no towing, heavy loads etc. The 14K run was the second to last row. The last row is the latest run.
 
If he's happy with 12,000 miles, then stay with it, but if he was wanting to extend to 15,000 miles, I really think the Series 3000 could give him that advantage.

Do post the rest of the numbers as well.

LCM – THANKS for posting all the numbers. See now that I look at it together – this UOA looks pretty darn good. New formula TSO holding up OK, wear metals well within control.

I think you shouldn’t pay much heed to the “horrable” comment, I think he meant “horrible” – but more importantly, it’s just a crack comment, not a professional opinion.
 
I was always under the impression the sludge issue was with short trip drivers, with the miles this Durango is seeing it definitely is not short trip. Am I wrong in this short trip assumption?
 
that looks pretty good, 2ppm/1K miles iron, no lead, low chromium and tin. viscosity is high except on the last one.

could consider LC/FP for an interval...
 
You mean ASL, right Pablo?

At least the UOAs are consistent with each other (aside from viscosity) so nothing "new" has begun happening to alter the results.

If sludge/varnish formation is a fear, use the Amsoil engine flush at the end of each 12,000 mile OCI.
