have a couple of questions? the trans is a stick 4spd with o/d does anyone know the actual mpg this truck gets not a guess but the actual figures. second is 316000 miles a lot of miles for this engine or is it just broke in . and 3rd how hard is it to repace the oil pan and front main seal. a video of my truck or a walkthrough for this job would be cool just send me a link to the website. the diesel is before the powerstoke was put in the 250 thanks
