Yesterday i changed my oil in my truck and after i filled it up and turned it over and topped it off, and ran it for like 5 mins. i pulled the dipstick and the oil is black like i never even changed it. And all 13 quarts came out and went back in im stumped. Anyone ever here this before and the truck dont run nearly as good as it did, has like a funky miss to it but not really bad. truck has 218k on it, always change my oil every 3,000. Could injectors be to blame for some weird reason since they are orignal. i also have a tony wild man chip on it. all my mods are in my sig. My buddy is gonna run it on his scanner anything i should look for?
