Change History

... since I believe that including additives makes for a better (not lesser formulation).
If motor oil's only intent was to lubricate parts, then I agree, but motor oil serves many other functions as well:
• Cooling
• Protecting
• Cleaning
For these additional requirements is that pure oil needs to be fortified.
These additives help with heat transfer, anti-wear and internal cleaning, among others.
ZDDP, Zinc DialkylDithioPhosphate is probably the best anti-wear agent there is for oil, but it's regulated because of environmental issues.
In my point of view, for my car, the more the better.
I had used Mobil1 15W50 because it had the highest amount of ZDDP in the market (Phosphorus:1200 ppm, Zinc: 1300 ppm)
I now use Mobil1 0W50 Racing because it contains Phosphorus:1750 ppm, Zinc: 1850 ppm.

If you'd like to read more on oil, here's one of the Tech Articles I've written for a couple of dozen PCA Regions:
