Maintenance Schedule

[Vincef329]

Hello,
I see a number of posts asking about when to do such and such. Attached is a .PDF maintenance schedule from my 2020 user manual. Reading through this in detail I understand some of the confusion, it's not written plainly in many aspects but here it is. If you see any issues don't hesitate to let me know.

I would view the maintenance schedule, which likely has a marketing influence, to be the minimum to (a) maintain factory warranty and (b) for the drivetrain to survive the warranty.

Suggest 5W40 in cool climates and 10W50 pure synthetic where ambient exceeds 104F (limit stated by XPS for their synthetic blend) .
Change engine, trans and final drive fluids at ~1,000 miles (see crud on magnetic drains in links below).
Change all thereafter in 5,000 mile intervals
Change trans air filter in 5,000 mile intervals
Engine air filter may go 10,000

The change to iridium plugs is suggested only for spark plug life, at the first spark plug change.
Performance differences negligible.
