I'm pretty sure you're wrong, but it would depend on where you live. If most of your driving is on blacktop roads, in a rainy climate where the dust and dirt get washed off regularly, then you might not be sucking in that much contamination.
But if you live in a dry climate, or drive on gravel very often, then a lot of that contamination will end up in your crankcase.
I think more than one of the experts here will tell you that good air filtration is more important than which oil filter you choose. IOW, pick a good air filter and not worry so much about the oil filter.
Lastly, I do not understand those who argue about how much money they've saved by not replacing paper air filters every 20k or 40k miles.
Your proof is where???????
