Thanks! Looks like Pennzoil and Mobil synthetics were pretty similar in their numbers. What's interesting is that Mobil 5000 had similar numbers to Motorcraft Semi-synthetic. Why would that be is Mobil 5000 has no synthetic oil in it?
Blackstone's cheap UOAs can not tell the difference between synthetic and dino oil.
To bring things back into context--
the engine could not either and that was the whole point of my experiment.
AnarchyX - not sure what you are trying to learn, but modern conventional oils are not those from yesteryear. You can see that I took MS5K out on an OCI much further than many on this site run synthetic and yet the wear metals were nearly the same. Also, for your benefit my FX4 was not a cream puff, it saw regular towing in varying climates and conditions. You also have to remember that UOAs only measure certain sized particles and therefore you cannot really use them to determine wear rates. Particle counts can help with that to a small degree as does trending as I did on the full life of the truck (I traded it at 158K, but the spreadsheet is every UOA performed on every fluid change).
I was just trying to learn if engines actually are affected differently if different oils are used in them, and if they wear down different oils based on what they're made of. And if there was a significant amount of difference in comparison.
