Hello Truckers report users. I'm learning a lot about the trucking industry and now I'm on oil analysis. I know that companies like BlackStone labs can do this but how do I really read and use the results? I know I can go to a mechanic to help me out but I want to learn some stuff on my own so I know what they are talking about at least a little.
I have a report ready to look at if someone wants to help. I'll even hire you as my go-to oil guy/gal in the future or mechanic reference. I'm helping out with a big truck purchase for a small fleet so I need some good help. Thanks!

Well, in all honesty, you can probably get a pretty good, low cost (free) education here. Share the results and inform us of the setup on the vehicle, where, and what you're hauling. There's alot of experienced pro's here that'll help out I'm sure.

dannythetrucker Thanks this.

Every oil analysis I've seen had a summary. That's what I would go by
jbatmick Thanks this. -
Wish I knew more myself. Thankfully DY posted a Detroit threshold chart I've saved. The lab will flag anything that would be abnormal. I'm still too scared to push my drain intervals too hard. Every lab test result I've received will have an overall condition status. Mine have always just said normal.

I use Schaeffer Oil, and their test lab - the rep will call you to discuss the sample if there is anything unusual. I'll be installing bypass filtration shortly to extend the drain intervals - from 13,000 currently to 30-50,000 monitored by the samples.
Cowpie1 is a good brain on the samples and wear metals/additive packages etc.
Post the sample here if you like so folks can pick through it with your questions. -
Here are the manufacturers "condemnation limits" as aggregated by the state of California (in studying extending oil changes on state-owned vehicles):
Theoretically, until the oil samples outside of those limits, it doesn't need to be changed.
You also use oil analysis to monitor trends to see if anything starts climbing at an unusual rate. For example (I'm making these #s up), your engine might normally add 0.2 soot for every 10,000 miles so when your engine starts adding 0.5 soot every 10,000 miles you might consider running an overhead.
Here is an overview:

Hey guys, sorry for the late reply. I tried to learn everything that you guys posted about. Here are the 2 reports I have:

Unit 2 above
Could you guys give some feedback? All looks normal no? Now this is the seller's own analysis. What are the chances that the seller tampered with the oil analysis somehow? Is that possible?
