Hi. Is there any trick to changing oil/filter in a 2001 7.3L poerstroke? I assume its like any other engine; drain oil, reomove old filter, pre-fill new filter as full as possible and install, replace drain plug and fill engine with new oil. I have access to the MC filter and Delo 15w40 oil. The vehicle is kept in a heated garage so 15w40 should be ok for winter.
