Could be lab variance but yeah it shows up low here.
I think it's quite a stretch that it's a terrible oil.
What do you consider solid results? Lack of catastrophic damage? Unless you've recently torn down and inspected the engine, it's hard to evaluate whether or not there's accelerated wear. It can take a long time to manifest itself.
Cite specifics. Hyundais in fact are extremely well known to explode due to poor manufacturing.
How is this for specifics:
Those reports are both from Blackstone, who have been known to show lower levels than other labs for the same oil, so I'd be careful inferring conclusions about concentrations from that data.
I sent PPHM to both BS and OA and both of them came back <600ppm on phosphorus. 540 for BS, 583 for OA. Either way, Pennzoil is hugging the line.
Yes, I suspect they are around 600-620 nominal, likely within the margin of error for OAI. Blackstone being 43ppm lower than OAI doesn't surprise me.
It's no different than throwing money away at other hobbies. I enjoy reading reports even if they are normal. What's the point of this forum then? Majority of the UOA posted here are just run of the mill.
So you can build a data trend which actually makes the use of UOAs valuable.
