I'm curious as to why you think that, and whether you have any data to support it.
Does oil analysis show that the limiting factor on oil life is particulate matter in the oil (which the filter might remove), or is engine oil life typically limited by things such as additive depletion, TBN, and viscosity loss, which the oil filter does not affect (although high particulate matter theoretically might increase viscosity).
I ask only because I have done oil analysis on several vehicles over the past 20 years, and I have never seen particulate contamination ever being anything close to a limiting factor in a non-diesel engine.
