oil analysis @ 6844 miles

[KIKER]

Changed the oil today and had them do an oil analysis to see if I've gone too far on my oil change. Here are the results:



aluminum 6

chromium <2

copper 5

iron 17

lead <2

tin 5

silicon 8

potassium <2

sodium <2

moly 65

water <2

oxidation <2

visc@100 14. 8

glycol ND

fuel <2

TBN 8. 2

nitration 2. 4

soot 1. 9



From all I can read about UOA, these number look good. It was with Chevron Delo 15w40, AFE oiled drop in air filter, oil fiter was Baldwin, I think. Local big rig oil change business has done almost all my oil changes and has the sample analysis machine there at their location. Any comments?

look real good to me, just had mine UOA and yours looks great.

How many miles on the truck itself?

Soot is a little high IMO. Are you sure it is 1. 9 and not . 19?

Some of the Analysis reports that I have seen around the web show a lot less soot than what you are posting whether it is a Cummins, Powersludge or Undurablemax. And yes, this is for all of the newest EPA mandated, more fuel burning, emissions tree hugging liberal engines.

If your soot % is in fact correct, I would suspect the Baldwin filter.

About to turn 60,000 miles.

I looked at it again and it reads 1. 9%. I am running a Fleetguard Stratapore on this oil change, fuel filter as well. Will do an analysis and see if the soot lowers on the next change.

That's cool. I was just checking. Anything 2. 0 and lower is good from what I have read.

I started doing oil analysis two oil changes ago since I started running Amsoil AME 15w-40. I have stuck with the 1yr/25,000 mile schedule. I don't an analysis anywhere inbetween. I do it when I change the oil.

First time I used Stratapore filters and changed them every 7500 miles or so until I reached the 25,000 mile mark. Soot was . 9%

Second time I started with a Stratapore, changed it at 7500 miles and then put a Amsoil EaO80 on and left it on until it was time to change the oil at 25,000 miles total. Soot was . 1%.

The reason I did the weird thing the second time was because I had one Stratapore left and I wasn't going to let it sit there and collect dust.

Soot is about normal for no bypass and that many miles. I was at 3. 0% at 19702 miles. According to OAI Cummins condems oil on the newer motors at 7% soot. Good oil will keep the soot suspended, which makes it harder to filter, but you still filter out a lot of it.



The 6. 7 with EGR deletes shows VERY low soot number because the cam profile doesn't have the in-cylinder EGR that the 04. 5-07 has.
