* Which engine is in your Range Rover? (e.g., 4.4L V8, 4.6L V8, 2.5L Diesel, etc.)
* What is the mileage on your vehicle? (This will help determine if you need a thicker oil for higher mileage.)
Once you provide this information, I can tell you the specific type of engine oil (SAE viscosity, API classification) and the recommended oil change interval.
You can also find this information in your owner's manual or by checking with a local Land Rover dealership or a reputable auto parts store.
