As far as Mobil1 goes, I have some real world experience with it and I can tell you right now that this is one of THE WORST synthetic oils that I've ever seen. Its not even Grade 4 synthetic oil.
Here is the summary of the oil analysis that I did a while back for my VW. The analysis was performed by BlackStoneLabs and if interested, I can provide you with all the original reports from the laboratory.
Interesting data you have there.
I also think it's interesting how I can't find 0w30 in Southern California but you can find it in Chicago.
I'll agree that Mobil1 5w30 is crap but I'm surprised about the 0w40 results.
It's going to be interesting with the results that I find with the 5w40 that I'm trying.
