1st Oil analysis

[V10nacuda]

Just bought the truck & after reading some posts I decided to get the oil tested. The truck has 33k & I think maybe 5k on this oil change. I changed the oil & drained the filter in a bucket & it set for a few days before I took the sample. Will that effect the results?? (sample kits says to take hot... . however the kit was obtained days after the oil change)

The only thing that seems odd is the copper count that is 30ppm. Where is the copper coming from???? Premature bearing wear???

Oil was probably 15w 40 rotella or some autozone brand



Al-3 Chromium-1 Copper-30 Iron-18 Lead-3 Molybdneum-14 Potassium-9 Si-7 Sodium-5 Tin-1 Zinc- 1042

ppm



ST-54 OXI-0 NIT-0 SUL-0 W-N A-N F-N V100-14. 4 ct/ml

Copper : Brass or bronze parts, copper bushings, bearings, oil coolers, also an additive in some gasoline engine oils.



Blackstone Labs - Understanding the elements



I think that you are supposed to sample midstream with oil circulated. This way you get a good representation of everything in the oil. After it has been sitting I would believe the denser elements have settled out.

While your results seem reasonably typical, I'd personally find other places for my $$$ than using oil that's been sitting around in a bucket for several days after draining for an analysis...

1st Diesel, wasn't aware of the sampling procedure, unfortunatly I had bought it after the oil was drained out. My luck I would have put the kit o the shelf in my garage & lost it so it would have been $14. 00 down the toilet anyways

I use http://www.blackstone-labs.com/, the kit they send you is free. All you do is send in your sample along with payment and they send you a new kit for your next oil change.

Your results are typical for a new Cummins. Wait 20K and try it again, it will be normal.

To get an accurate oil sample, first clean the whole area of the oil pan so it is free of dust and dirt, then take it mid stream with the engine oil hot.



If you drained the oil into a bucket and took the sample from the bucket, it is contaminated even if you think the bucket was 100% clean, it's not.



I work for a deere construction equipment dealer and we take lots of samples, you should hear how deere the corporate company wants it done, well from a sample gun at least, put the bottle in a plastic bag, open the cap in the bag, screw it onto the sample gun throught the bag, poke the new sample tubing through the bag, take the sample, and reverse. They think your shop should should be operating table clean, yeah right.

"Per Caterpillar, high levels of copper found in oil analysis are a result of engine cooler core” leaching". The Zinc additive in Diesel Motor oil reacts with the copper cooler core tubes at high oil temperatures. This chemical reaction results in copper oxidation products forming on the surface of the tubes and then coming off into the oil as it washes over and around the tubes. Heat is a catalyst to this chemical reaction. The higher the oil temperature the greater the rate of oxidation and the longer the reaction process is sustained. This does not cause any damage to the cooler core, or to the engine. However, you will see the copper reading elevate to over 100 PPM. Copper is not a particulate in this case but is in solution in the oil. The PPM will start relatively low and increase over 100 PPM and stay at high levels for several intervals, and then return to normal. During the oxidation process, a hard film forms on the tube surfaces exhibiting the appearance of clear varnish. Changes in operating temperatures, and/or changing oil brands can chemically disrupt this film and begin the oxidative leaching processes again. This can occur in any system with a cooler core: Gasoline or Diesel engines transmissions or hydraulic systems. "
