4 quarts in 17000 miles is not alot of make up oil. FWIW I replaced the filter at 10,000 miles and topped it off, so that is one quart right there.Lot of makeup oil.
How was this truck used over the course of this oil change?
Good report for that mileage. 4 quarts could change how the wear metals look though. If you took a sample at 5,666 miles in the first oil interval it may give a different picture but I agree that 5,666 miles on avg per quart disregarding the oil filter as the 4th is not bad. What filter did you run & changed to... Fleetguard?
Has the truck been deleted?
Hard work explains the oil consumption.pulling this from SWFLA to the Arctic Circle and parts in between and back . otherwise it was unloaded.
about 11000 miles pulling this
3 gallonsIsn't the sump capacity of the 6.7 5 gals? That's more than others which may help.

Is there an existing filter that could take that kind of mileage? Makes me think the original OCI could have been ok without the filter change. I realize my question could be self answered but not sure if i can stare at 50 UOAs from a website forum format. I want unfettered access to blackstones database
Personally I wouldn’t hesitate to run a Fleetguard LF16035 for that duration.Is there an existing filter that could take that kind of mileage?
