Kenworth oil analysis [b]Update not good![/b]

[2hellandback]

2003 kenworth T-600 475 cummins ISX 818,580 total miles
10,000 Mile sample taken just before the oil was changed, So whats going on with this engine?

iron-41
chromium- lead- copper-11
tin- aluminum-11
molybdenum-8
silicon-58
sodium-17
potassium-8
water- oxidation-7.8
v100c-14.8
glyco-0 none
fuel- tbn-7.7
nitration-3.0
soot-1.7
v40c-113
vindex-135

aluminum abnormal
silicon severe
all others they listed as normal
A total of three gal of oil was added in 10,000 miles

I sent one to them from my t-600 kenworth truck,,, they ran the test and based it on 15,000 mile oil when the reported milage i reported was 5,045

I talked to them about this and what they have people trained to run the test equipment that dont have the foggiest idea how to interpet results.I explained that for example 24 ppm tin might seem fine for 15,000 mile oil but might be critical for 5,000 mile oil he acted like he didnt understand why !!! Am i crazy asuming this oil test was a total waste of my money?

Test Results:

iron-17
chromium-13
lead-13
copper-17
tin-24
aluminum-14
molybdenum-8
silicon27
sodium-21
potassium-12
water- oxidation-7.0
v100c-14.6
glyco- blank,,, none i guess
fuel- tbn-8.8
nitration-2.5
soot-1.1
v40c-113
vindex-132

12 gal oil capacity
Oil was mystic 15-40 synthetic blend
And 1 gal was added at about 3,000 miles.

Can anyone interpet this and tell me if something might be critical or even if i need to change the oil yet?????

Any recomendations on who i should sample through next time ?

Thanks!

what engine do you have and how many total miles are on it?

Looks like it is still in the early break in phase. Some engines take a long time for the wear metals to get low and stabilize. I don't see any issues here. JMO Ed

818,000 miles I think it might be past the break in period.

Im wondering if Lucas oil stabilizer might be a good product to run in this engine?

First of all, who took the sample? Was it a tech who was a little careless and took it from the oil change pan. (Has to be asked)

818000 miles is gettting up there...(I know a lot of Cummins go farther), but that potassium number looks to be creeping up on you...and if it is coolant, you know what that does to the bearings as well as everything else.

That silicon number is high...was work done recently? If not, have one of your guys who pays attention to detail (or even yourself) go over every part of the air intake, intercooler, anything that takes in air looking for a leak dirt ingestion causes wear when it gets as high as your numbers.

About your Lucas question...there used to be a demo on what Lucas oil stabilizer did to an engine. It's NOT pretty. It may be on the Home Page of BITOG.

If I was going to change anything in this engine, it would be to add Mystik's 15W50 Semi syn that they have...you seem to add a lot of oil in a relatively short time.

put on an oil sampler kit if you don't have one already

Cummins may want a virgin sample of your oil
run a UOA thru them.
if they can't diagnosis your oil, no one can

if you don't like Cummins NP, try Butler's.
you probably run right past one of their front doors.
they do all breeds and are top guns in HD commercial engines

stay away from any oil additives. if Mystik won't protect your engine, nothing will

get a top gun diesel shop to test your intake system from filter to turbo for ingress leaks. you're sucking in dirt. cause of high wear metals numbers

I'm not a pro but here is my thoughts.
Has any work been done to the engine reciently? Silicon is very high.


If it's not from sealer it's dirt getting into the cyls and causing high iron wear.

May also have a slight coolant leak. Cummins are known to have headgaskets that weep. It's small and is not hurting anything.

Could also be from a contaminated funnel when the oil is added.

At 807,000 a new water pump was installed. Sounds like i better stay away from lucas oil stabilizer then?

Do you think it's a possibility that the gasket used to replace the WP may have not been 100%? Just throwing that out there as an idea...
...and yes, stay away from the Lucas OS...If you use lots of oil ove a short period, try the Mystik SB 15W50 like I mentioned...it may cut down your consumption.
