The abstract said that "Tests were conducted to establish a relationship between the level of filtration and abrasive engine wear."
There remain other kinds of wear, especially that due to lack of lubrication during cold startups. Wear due to acids in the oil is also possible if the additive package (particularly the total base number) wears out before the oil is changed.
It would be interesting to know how much wear is typically due to abrasive particles as opposed to cold startups. I've always heard that most wear occurs when the engine is cold. That's probably true, but I haven't seen any research to support it.
One of the best ways to keep abrasives out of the oil is to have a good air filter. To expect an oil filter to make up for poor air filtration is begging for trouble.
