Typically every 30,000-40,000 miles
Transmission Fluid Service:
Variable, often recommended around 60,000 miles for ZF automatics
Engine Oil Diesel:
e.g., Castrol EDGE Professional OE 5W-30 (meeting specific Land Rover specifications like STJLR.07.70.17)
Engine Oil Petrol:
e.g., Castrol EDGE Professional A5 0W-30 (meeting specific Land Rover specifications like WSS-M2C913-C or similar)
