I've got a 2011 Sportage CRD1 4WD coming up to 12mths old. I assumed that service intervals were every 12mths although the service record book doesn't actually say this (except for the anti-perforation inspection which is every 12mths)and it refers back to the owners handbook. The handbook is a bit ambiguous but clearly shows normal maintenance schedules every 24mths or 20,000 miles (p7/12 on), and states "If the recommended engine oil is not available replace oil and filter every 20,000mls or 12mths" (could be a printing error as it then says the same thing for every 15,000mls).It goes on to give 12mths or 10,000 only for"maintenance under severe usage conditions" (p7/20).The Kia garage say every 12mths or 18,000mls for all conditions. As a service is usually £200 or more(mostly cost of oil apparently) it makes quite a difference. Anyone know definitely which is right? Apologies if I've missed something glaringly obvious.
