First oil Analysis-NOT GOOD CHRYSLER!

[Gifford]

I just received the report for an oil sample out of my 2006 3500. The report noted a concerning result: Silicates @ 30ppm (parts per million) This sample was of the OEM supplied oil from my first oil change @ 4,000 miles. The report speculated that the silicates are likely from dirt/dust contamination or bearing surfaces. ALthough 30ppm was not cause for immediate action the report did indicate it was cause for some concern. I'll be sending another sample from the second oil change. THe report also mentioned that since I didnt provide the Specs for the OEM oil (I didn't know what type/spec oil DC put in) it somewhat limited their analysis.



I am worried that there may be a problem with the OEM air filter subsystem.

I would not worry too much. Wait untill your second change and see what happens. It is quite possible that the oil analysis guys know what they are talking about. With that said I would still go out and look at your air box and intake hose/tube to make sure there is not a big leak.



You can always pull a sample after 1000 miles and have it tested without changing the oil.

Same thing happened on my first report. Just got my second analysis back on Friday (17k miles) and the numbers all dropped drastically ! Things are looking really good. Only Potassium stayed high, not sure what that means. In addition my fuel mileage for city driving has gone up from 16mpg to 18. 3 !!! I did however, recently install the new 7 micron fuel filter but I don't know if that effected mpg or not... . ?

Analysis of oil from the engine's first oil change will often appear radically different from accepted norms, due primarily to break-in wear, as well as some of the sealants used in factory engine assembly - I wouldn't be concerned - and probably wouldn't (and didn't!) bother with analysis until a few oil changes have been performed.



Elevated wear metals will often be somewhat higher than normal out to about 40K miles, where they usually level off.

I am worried that there may be a problem with the OEM air filter subsystem.

Remove the air filter and if you see dust around the corners, apply a nice bead of silicone caulk around the upper part of the seal and re-assemble it.

When it's replacement time, silicone peels easily from the urethane seal on filter.
