Trip Computer "OIL"

[HPsauce]

I think it's OK, I happen to have my manual in my office and just looked.

The service info appears (briefly) in place of the Trip Computer mileage - is that where you're seeing it?

The options are OIL, IN 1 and IN 2.

I've never seen OIL, but it gets regularly changed anyway at humungous expense!
(I don't do a huge mileage so the Inspection timer probably kicks in before mileage warrants an oil change)
