Hey Folks, changed my
oil & filter as typical and installed M1-204 Mobil 1 filter + 5 quarts Castrol. Fired up,
oil pressure fine, no leaks. Check level and level is high. Pulled off filter and only get about 4 oz of
oil to pour out, but filter seems to be heavy enough that more oil is held inside. Is it possible, filter defective and bypass valve is open? Anybody else experience before?
