Filter manufactures like to have better profit margin. Selling premium filter at much higher price while their cost is slightly more, extra large profit per filter is always nice to their bottom line.
From my experience with oil filters in my 350+k miles LS400, any filter even the OCOD can easily be in service for 14-15k miles, as long as you change oil regularly i.e, 6-8k with dino and 12-15k with syn. Also, don't let the oil level get to below minimum mark on the dipstick i.e, don't let your engine has more than 1 quart low.
