I disagree. It's very important to fill the oil filter first. If you forget to fill the oil filter and start your car and remember you forgot to fill the oil filter IMMEDIATELY shut your car down, drain the oil (there are extra metals and wear particles because you forgot to fill the new filter with oil), refill with fresh oil, do a UOA of the old oil, put a new filter on filled with oil (there might be metal in the old one due to the millisecond it took to fill it) package the old oil & filter up and PM me so I can dispose of it properly due to the extra metals from an unfilled oil filter (I'll pay up to $10 in shipping if it's a name I've heard of synthetic), then turn your car to the "on" position and off 3 times, then start it, flash your high beams 5 times, and drive with your flashers on for the first 25 miles. It's IMPERATIVE you follow this procedure but ONLY if it's 0w20 and a filter that fits a Subaru or Toyota because I need the used oil and filter you RUINED for my cars.
What's your mailing address??
Is there proof of this? I have never seen a test of (1) delay time in oil pumping to upper oil galley (valve train) from dry oil filter, nor (2) measured wear metal differential between dry & full oil filters.
