Only a small amount of the oil is run through the filter. In the case of the AMSOIL single bypass filter system, that oil is pumped through the filter and returned through a restriction about the diameter of a paper clip. This insures that the oil pressure remains high (and the return line is low pressure.). If you want to e-mail a snail mail address, be happy to send you a brochure which better explains it. Just got an oil sample report back on a Ford Excursion with 7.3 PowerStroke diesel. He changed the oil and installed a Bypass filter at 5,000 miles. At 50K, 45,000 on the oil, it is still suitable for continued use. Soot is 1.4%. He has sampled, and then changed full flow filters, but has not yet changed the bypass filter. Dick in Falls Church
