I know Honda and Toyota are obsessed with quality. (I've known engineers here in Colorado, two worked for Honda's high-altitude testing lab/field-office, and one Toyota hired as a consultant for heat transfer analysis on the Prius.) .... I was explaining the oil-gelling problem Toyota had on poor oil filtration, although it probably had more to do with water condensing on cool spots on the inside of the engine, etc., not sure, maybe a combination of both.
Sounds like Toyota agrees with dnewton's "dump less oil, as not all gets recycled properly. Maybe with future forced incentives to use oil longer, we might see the wear rates for filtered oil become more significant within warranty periods. .... We enthusiasts want less grit in there now, so a couple extra bucks for a Fram TG makes sense.
