Routine service items

These are the items covered in a standard service. Most garages include oil, oil filter and a basic inspection. The rest are typically checked or replaced on a schedule.

Service item	Interval	Typical cost

Air filter Manufacturer interval 30,000 miles. Check more frequently in dusty conditions. Clogged filter reduces performance on these naturally aspirated engines. X100	30,000 miles	£40–£60 Dealer: £80–£120

Periodic maintenance

Items that don't need doing at every service but should be on your radar at the right mileage or age.
