Right. People can say/think low additives wear just fine, but if you took 2 engines made with the same tight tolerances (almost impossible), drove them the same for, say 250k, one with a robust, beefy add. pack and one with the weak add. pack, I BET the engine with the beefier add. pack wears less & lasts longer. That's what I'm getting at.
But, most people don't keep a car 250k, so most don't care which add. pack they use, cause the car will be someone else's!
I agree. But you know, I bet it would be hard to determine that from just UOA's
In fact UOA's may show the opposite. The stronger add-pack oils sometimes yield "worse" UOA's because of the higher additive concentrations.
Now, THAT would be a good analysis to do.....
But, you know, they may drive the car harder too.
