We now have 4 VOAs of the most modern formulas of popular High Mileage oils in my VOA Database. I've isolated them out for easy comparison for your viewing pleasure.
All 4 VOAs are from Oil Analyzers, which happens to test for Oxidation. Oxidation, according to Lake Speed of Speediagnostix, can be an indicator of esters added as seal conditioners in HM oils.
The last 2 lines (Pour Point and VI) are taken from PDS sheets.
The only major off the shelf brands I'm missing are SuperTech and Quaker State. I'm out of sample containers and I've already spent ~$120 on three of the four VOAs listed above. I would be very grateful if anyone wanted to contribute VOAs for the newest ST and Quaker State HM 5W30s (from Oil Analyzers for more direct comparison)! The Dexos 1 Gen 3 versions.
Enjoy.
