Car will be one year old mid September and the car has flashed up in 700miles oil service is due or 77 days, current mileage is 8646. I know 700 miles is an estimate but that would only bring my mileage to 9500 not 10,000 which I thought the service interval was, 10000 miles or 1 year whichever is first. How many miles can you exceed when the car says the service is due? Cheers.
