Seat are looking for your commitment to them, if you have you car serviced at a seat dealership then the car will be worth more when you come to sell it, a service will show up any potential faults and bring to light any safety issues that may have occured.
The service light is triggered by an internal computer that bring the light on around every 12months or 10kmiles.
If you dont want the oil changing as it seems ok in your opinion then ask the dealership to carry out an inspection service where the car is checked-over and all the levels and lights are checked - so nothing has been left or avoided and they'll still stamp your book for you but you wont have to pay for oil (around £30) or a filter (around £5). Then next time have an oil change and inspection service at the same time
