Using incorrect oil viscosity can lead to increased engine wear, reduced fuel efficiency, and potential warranty voidance. Thicker oil than specified may cause poor cold starts and increased fuel consumption. Thinner oil may not provide adequate protection under high temperatures.

For optimal engine health, check oil level every 2-3 fuel fill-ups or at least once a month. Always check when the engine is warm and on level ground. The electronic dipstick in the infotainment system provides the most accurate reading.

While Land Rover recommends 10,000-15,000 mile intervals, consider 7,500 mile changes for severe conditions: frequent short trips, extreme temperatures, towing, or stop-and-go traffic. Modern engines are sensitive to oil degradation.

Dealership service typically costs $300-$500 including parts, labor, and diagnostic check. DIY can cost $100-$150 for premium oil and filter. Consider that dealership service includes warranty on work and proper disposal of old oil.

Navigate to Vehicle Information in the infotainment system, select Oil Life, and follow reset procedure. For exact steps, refer to your owner’s manual as the process varies by model year. Failure to reset will cause service reminders.
