Looking to commission oil analysis on various new oils, both hydraulic and engine oil, for competitive analysis. Looking to measure the best indicators of quality and longevity.

Here's what I was thinking for engine oil:
  1. Additives - Calcium, Magnesium, Phosphorus, Zinc, Barium, Boron
  2. Contaminants - Silicon, Sodium, Vanadium, Potassium, Lithium
  3. Viscosity
  4. Oxidation/Nitration/Sulfation by-products
  5. Wear Metals (shouldn't have to, but I've done previous testing new/used oil, same brand, and wear metals are present in brand new, outta the box oil)
  6. some type of lubricity, or wear testing
  7. anti-foam
Same testing for hydraulic oil, possibly with water solubility added.

What am I missing from this list to gauge similarities/differences between oils and their overall quality, compared to the standards for their usages?
Also, there are several rating standards for each use case, which are the most common/most important?

Bonus! I'll share the results with IBB when I'm done. Suggest oil brands to be tested. I probably won't select the one you suggest though as I'm doing this for my purposes, not yours:laughing:, but it it fits within my purposes I'll consider it.
 
I'll nit-pick a little, a petroleum engineer is the last person I would ask those questions to. Their training is to get oil out of the ground in an economically viable way.

We do a fair amount of lubricant testing at work but 99.99% of the time as long the lubricant is close to the right viscosity (IE in our last lubricant related issue someone was lubing bearings with coupling grease) and not full of water it does the job.

Some truck stops provide oil analysis, speed one that comes to mind.

wrong terminology then. Whatever the fuck enginerd that would be involved with formulating oil additive packaging for base stock oils to meet industry standards.

Going to use one that we’ve got a relationship with at work, I’m tagging this onto a package deal, should get the cost down to 40/sample
 
I'm thinking about shying away from re-using oil
I was draining it early-ish then letting the particulate settle out for a year or so before dumping it back in there

anything brand new from a bottle? probably betterer
 
I guess my reason for wanting to do this myself is I’ve seen what truly comprehensive analysis is and most companies won’t publish any of it, the ones that do typically give you a few constituents that they are better than the competitors, with testing paid for by them. Some of the internet guys’ methods are sketchy, and hard to replicate. When they pay for labs many leave stuff out I’d like to see.
 
Blackstone, CAT and others will give yout the test sheets they use and what test they conform to (ASTME or other). We use FOI labs at work for generator fuel testing.
 
lol what a waste of effort. Any oil made by the big guys is gonna be fine for what you’re doing. Any small percentage “better” that one is from another will not be seen in the life of what the oil is going into.

To make what you want last longer change the oil more often. Simple as that. I buy more oil in a year for my shit that most people do in 2 lifetimes. Of all the engine failures I have had they were all do it fatigue, foreign object, water intrusion, dusting, ran out of oil ect.

Agreed, at least on engine oil, though VVT/VCT/MDS does change things slightly.
This is more a sales tool for my other job.
Hydraulic oil, specifically for hydrostatic applications, is slightly more complicated, though the premise is still valid.

This has less to do with change intervals and more to do with “meets or exceeds OEM”
