I know my '04 Hyundai Elantra was 7,500 miles/6 months for normal service and 3,000 miles/3 months for severe service (not sure when the severe interval went from 3,000 to 3,750).
Also, the list for what is severe service is almost any driving condition, and meeting one of these puts you into severe service.
- Repeated short distance driving.
- Driving in dusty conditions or sandy areas.
- Extensive use of brakes.
- Driving in areas where salt or other corrosive materials are being used.
- Driving on rough or muddy roads.
- Driving in mountainous areas.
- Extended periods of idling or low speed operation.
- Driving for a prolonged period in cold temperatures and/or extremely humid climates.
- More than 50% driving in heavy city traffic during
This is why many (including me) recommend/follow a 5,000 mile interval for most Hyundai/Kia vehicles, right in the middle of the normal/severe interval since that is where many are.
If under warranty and you're worried about it, do it every 6 months if mileage not reached, if not in warranty or not worried about it, then annual if mileage not reached.
