just changed oil recently & sent a new analysis away.
Truck has 149444 kilometers, or about 93000 miles on the engine & a little shorter OCI than the last one.
Looks like a pretty good report, but seeing silicon on these last 2 samples have been above the average.
Have noticed some oil seeping on the engine, looks to be coming from above the starter, & 1 intercooler line appears oily on the outside.
Maybe I will have to check/ tighten hose clamps on intercooler line.
Also replaced the air filter at the same time.

Having problems trying to attach a PDF of the analysis report. Will try to figure something out. Not as convenient when I need to manually enter it all.

Great reports, I wouldn't change anything. The silicon level looks fine for an 8,300 mile run. I would expect to see less than 10ppm/5,000 miles with a paper filter.
