I guess if we're really talking oil, I might as well include a Blackstone report so folks can see. The oil change at the 500,000 mark was Valvoline Premium Blue and had been for the last several oil changes. The others are labeled on the sheet, but include Rotella, Mobil Delvac, & Delo.

The cheapest clean oil is better than the priciest dirty oil.

Ckd out the chart. Don't know anything about that type of info.
What potential problems or benefits could be associated with the numbers on the metals and other stuff?

Certain numbers represent wear metals from things like bearings or engine hard parts, or dirt injestion. That's an indicator of engine failure that's about to happen.

Others rows are about additive packages to aid in lubrication, viscosity, protection, etc.

You can do a lot of studying on sites like bobistheoilguy and try and learn all about those numbers, or you can get a sample done with a very basic understanding and use it as a baseline to track trends or spot a pattern. As you can see from my chart, testing from 265,000 miles up to 500,000 miles showed the wear metal numbers to be relatively flat. If they showed a consistent increase every 5k - 10k, then that would be cause for concern.

So with my 2000 7.3 F350 you suggest a test now at 154K to give a baseline and ck for overall current picture. Truck was new to me 1 1/2 yrs ago. No paper work nor history.

Then how often to the lab (at I think $40 now to Blackstone)? Next oil change after test or wait how long to 2nd followup test? Depending on results of 1st test of course.

Here is a good primer on how to read a UOA...

Cheat sheet for newbies reading UOA's | Used Oil Analysis - Diesel | Bob Is The Oil Guy

Personally you can send in a UOA anywhere between 5-6000 miles I think makes the most sense. Anything under 3000 isn't worth it. Just a heads up blackstone is popular but not the only game in town. Polaris, Caterpillar, John Deere, Cummins, Schaeffers... all offer UOAs. They don't give you the little text box but I have seen BS reports that make me wonder what UOA they were looking at when they wrote it up.

No need to to it very often.. A couple back to back or near back to back oil changes might be useful in establishing a baseline, but if all the numbers fall into the normal categories, I wouldn't bother with a test unless you are worried about something, or maybe do one every 50k or 100k or couple of years depending on driving habits.

Have you considered the John Deere 50 plus 15W-40 during the spring/summer months?

considering the John Deere 10W-30 plus 50 for my 6.0L - excellent used oil analysis results and less shearing than the 5W-40 oils.......and the price is nice, especially during the spring & fall sales promotions.

x2!!

I prefer UOA reports that show oxidation & nitration values since this show how much life is left in the oil......




here is another good explanation of what some of the values mean......
