Agree. My point is that the chance of contamination by prefilling the filter is slim to nothing. I always prefill my filters.
As for engines being robust, I heard that you actually don't need a filter after the first few oil changes where you are filtering out machining debris and casting sand particles that remain from manufacture.
I recently ran a 4400 mile oil interval on my motorhome with a filter having an efficency of 68 percent at 30 microns (this would make some cringe at thoughts of contaminants getting through). The used oil analysis was outstanding (and the manufacturer recommends 3000 mile oil change). But this filter flows 15.85 gallons per minute, nearly twice that of a Purolator filter (which I believe filters much more finely). Anyway, the filter was a Fleetguard LF 697 and I may just go over to these all the time. I want a good flowing filter.
