Where can you find the information? Looking at a lightly used rig and can't find it anywhere. I come from a Toyota background so maybe you don't get that, but I'm accustomed to seeing and being able to plan what's coming up next. For 40k all I see is to change the gearbox/trans and diffs, not sure with what oil type. I inspected and drove the truck last night and snapped a few pics underneath that I posted in my intro thread; one cover has some surface rust on the driver's side area and I'd greatly appreciate if someone could tell me what that is and if there's an aftermarket replacement that's more rugged for protection. Other than that everything seemed to check out just fine, despite not being able to find how to check the average MPG on the instrument panel.

Timing chain/guides, what's the recommended interval on them?

Is there a way to check the full/proper operation for the air suspension?

 

You will see a lot of different schedules.

My 2015 TD6 I go by my rover mechanic's ( over 25yrs experience) oil and oil filter every 8K, Fuel filter every 16K

Great info, thanks a bunch! Nice that there are Mann parts on Rock Auto, or Atlantic British.

 

how often do you do the front and rear diff? Any guide on this? Frankly I just do oil changes every 10k miles. Haven’t done a fuel filter yet. Have 48k miles. Where’s that located? I do change my air filters every year.

For oil Shell Rotella in the big jugs has been my go to. I still have some F150 oil I’lol use when I remember to but Fodd came out and like Dodge/Jeep has stated they recommend the Shell Rotella as well. The stuff is just good and it’s easy to find.

 

Do you know the capacities of each; Diffs and t-case? I see the motor is 7qt which isn't bad at all.

60K is when I'm changing mine.

 

Fuel filter is on the driver's side firewall, slightly inboard. Not a difficult change. Slightly messy releasing fuel lines w/ spillage.
