I changed the oil today for the first time ever on my cummings and the guy at the parts store said it held 10 quarts but the dip stick said it was about a quart low, does it hold more? my powerstroke held 14 and another thing,is it normal to smell something like oil burnning in the cab, it smell like i spilled some on the intake and it is buring off but i washed the motor right after i changed the oil, any ideas??
