Generally speaking service intervals are given as a mileage and timescale, such as 10,000 miles/12 months, with the guidance that the service is carried out whichever milestone is reached first. This is to allow for high and low mileage drivers. We would recommend that your service the vehicle every 10,000 miles to ensure your vehicle is kept in the best condition, and you would need to do so in order to meet the conditions of the warranty.
