VOA of Pennzoil Platinum 5W20

Not to nit pick but the report says 5W20, the text comments say 5W30. They make lots of mistakes, I wonder how many oil samples get mixed up with other customers samples. This causes me to wonder about the accuracy of any of their reports.

Is PP TBN really that high, that is in the area of an extended drain oil, isn't it?

Thanks Johnny for commenting. I've been reading lots of these UOAs trying to learn about them. I come across lots of mistakes and it casts a lot of doubt [at least for me] about the accuracy and the validity of them. All that has to happen is two of them get mixed up same grade of oil similar miles, one good one bad, and the person with the good report and the bad engine thinks everything is fine and dandy, then blows an engine. The other drives himself nuts looking for something wrong with a perfect car. Jury is still out for me, at least for now.
 
That TBN can't be right. Even Amsoil Virgin shows less then their data show.

Still awesome oil and can see why even though Penz doesn't promote EOCI it can be done. Thats why we so great 10,000 mile UOA

I agree with seeing a lot of mistakes recently. This isntance it could be someone fat fingered the keyboard when typing as the 2 and 3 are next to each other or they thought it was5W30 for some reason. Sadly no way to tell which it was. I was surprised by the TBN also, I would send in another sample to another lab if I had money or the little bit still left in the bottle but I do not have either. I am sure this oil though will be fine for 8000-10000 miles with 90% of that being highway mileage.
 
Q Horsepower came back with a 10.0 TBN with only 2680 PPM calcium. PP 5W-40 was 10.3 with 2116 PPM calcium. Maybe the calcium used in PP gives a higher TBN per PPM?

All good information here. My problem is the point of paying for the test is to take the guess work out. Here someone paid for a test and the best we can do is guess, since it is obviuos something is wrong. The lab should run the report again for free IMO, and be just a little more careful this time around. Even then I'd have my doubts though. Sorry JMO
 
I saw a Valvoline VOA where the TBN was 8.5 and it was said that TBN is based off of Calcium and it has half the Calcium Pennzoil Platinum does.
 
The TBN seems to match the Ca % and they are separate tests. Was the sample taken from athe bottom of the bottle? Many adds settle there; remember 1000ppm = only 0.1% by weight.
