No doubt driving habits are one of the highest variables. In any case this is more of a curiosity/academic trial as data analysis is some of my background. My drive to work is as consistent as it can get so I was thinking that is a good scenario to try and see what happens if I am patient and rely on the central limit theorem.
Besides the small cost of this product It does not seem that using Mos2 has any down effects on the engine based on my research (albeit limited).

Obviously, driving habits have the biggest effect.
I don't think one could realistically measure - in either direction - changes in wear from the additive, either. Unfortunately, all we're going to get is anecdotal evidence, so you may as well see what others' experiences are in similar applications to your own. Plenty of people here have tried the additive, and we don't hear a lot of hate against it. Alternatively, one could ask a formulator here or someone with a lot of experience with this family of lubes, like Doug.
I'm sure there are reasons XOM didn't put moly in this lubricant. I doubt that they were cheaping out, but, then again, this product is an extremely good value in Canada if you go to Imperial Oil, where it is, perplexingly, cheaper than it is in the States.
