Which oil to use?
Im not to familiar with what oil to use for diesel. I drive a 2005 250. And one cause of my job I can be at a place that is -40 one month and the next month be at a place that is 80. I don't think my truck has ever ran synthetic. Can I switch to it now? What would be the benefits? Any help is much appreciated!
