Ive got a 05 6.0. Bought the truck with a bunch of miles on it. 330k+ at this point. I dont have much of a service history on the truck. It currently has arps a 4" tb exhaust and a edge evo tuner as the mods i know of. I noticed the oil was low one day while messing with it. I added about 2.5qts. About 3 tanks of fuel later 300 miles per tank so probably 900 miles it again down 2qts. Im about to do a oil change on the truck but have been endlessly searching for steps to figuee out the oil consumption issue. So far it seems that the turbo, injectors, worn valve guides or worn out rings could be the issue. How would a verify which of the causes is the most likely to be the culprit?
