Virgin Oil Analysis - PCMO/HDEO | Forum profile

Is there a possibility that Blackstone mixed up my VOA sample with someone elses 10w-40 PCMO? The more side by side comparison I do, the more it looks like cheap 10w-40 someone had sampled - maybe even a short term UOA with the traces of wear metals. This doesn't inspire a ton of confidence in Blackstone as a first time user. What are some other labs and what are their costs for OA?

Some settling is possible. However, this looks more like Wal Mart Super Tech quality oil. I would stick with Delo, Delvac, or Rotella. Heck even the Motorcraft Diesel Oil product date sheets I have seen is better looking than this.

I cannot believe these numbers came from a well shaken bottle of heavy duty engine oil, even CJ4. The numbers are "adequate" for oil going into say a modern passenger car engine except the viscosity does prove it's an xW40 oil. Actually lawn mower oils have extraordinarily high levels of Zn/P. I believe Valvoline Premium Blue, out of a fresh, shaken bottle, has Ca and Mg ~50% higher, and Zn and P 2-300 ppm higher. These are the...

here you go. I found the VOA of LC20. It was posted Oct 2004. http://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=476795&page=1

Hope there would be an updated one though..

Call Blackstone and explain your situation. Perhaps they still have your sample and can run it again (some labs keep samples for X amount of time). If they are in error, give them the chance to correct it. Jake

How do I post the full sheet as above? Would save time from trying to type it all out. I'm not exactly sure, but I think if you can convert it somehow to a .jpg, then you could use the Code: [img][/img] html codes.

Blackstone strikes again!

First, LC is not designed to be used as a primary lubricant, but rather as a cleaner and an antioxidant, so the flashpoint is somewhat immaterial. The ratio of LC to oil is so low your oil won't thin at all. Special components breakdown and solve the carbon particles and break apart the sludge polymers, breaking the particles further and further as...
