IMHO, IF and only if I were running down the strip for say X times and then do a total teardown would I bypass running a oil filter.
But my engines are 95% street driven (HARD) and I will go about 7,000 miles between oil changes using a good Dino grade 5W30 oil so it will get a 20 micron filter. I am toying with running a Dual filter and/or a 2 micron (Amesoil) 'Bypass' oiling system.
