Yeah, I remembered you mentioning that when the sample was taken and how the guy was impressed as to how you were able to fill up his canister so fast. You don't think it matters where you got the oil from do you?

 

the best samples usualy come from sucking through the dip stick tube into the oil pan.

useing the return line from the filter can be used, however that bypass filter will remove certian metals that can tell you more about what is going on.

 

Are you sure it's Silver and not Silicon? Silicon would indicate dirt entry, this would go along with elevated soot levels. Make sure you check your air filter and all the connections to the turbo....

 

yup, says silver... here's the printout... Drew, why would it matter where it came from, all of the oil is going thru the bypass anyway...??

edit: you'll have to do a "Save As" and view it that way... I used Irfanview and it looked just like the original file.

 

you would be getting the oil as it is being washed through the engine, this will give you a true sign if something is wrong since the filter will hold stuff in.

 

 

Steve my truck is the same as yours five minutes after an oil change the oil is black never seen oil in a cummins go so black so quick. I have done four oil changes in less than 10,000 km and had the dealer do an engine oil flush to no avail. I have an oil analysis when I first got my truck at 47,000 km maybe it could be of some help. As far as the dealer could tell me the last record of an oil change was at 28,000 km. I cant post the test results if you would like the analysis let me know and I will email it to you.

 

idk ive never herd of silver being used in a turbo bearing its way to soft and flakey for somthing like that if u ask me but what do i know

 

It seems to me that it shouldn't matter if you're capturing the sample using the return oil from the bypass filter. Let's say the oil is "washing off" stuff like soot and bearing metals,and then the bypass filter captures those contaminants (if they're big enough to get trapped in the filter). The stuff that is so small that it doesn't get filtered out is what you're concerned with, so whether you suck it out of the dipstick tube or some other way those small contaminants will still be in the oil.

 

Lane if you could e-mail me your results I'd appreciate it.

From all the info I read on engine wear, most of the wear comes from particals greater than 2 microns, I think that since the bypass is filtering down to the 2 micron level, most of the hasrsh stuff never makes it back into the motor. now what would be interesting is to see what the analysis would show if there was a pre-lube setup used prior to startups over the same amount of mileage (another item on my list of things to upgrade...).
