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
Engine oil and filter Manufacturer interval 10,000 miles or 12 months. TF, JF	10,000 miles or 1 year	£80–£120 Dealer: £120–£180
Air filter Manufacturer interval 20,000 miles or 2 years. Replace more frequently in dusty conditions. Clogged air filter reduces power and increases fuel consumption on diesel engines. TF, JF	20,000 miles or 2 years	£20–£40 Dealer: £40–£70
Cabin pollen filter Manufacturer interval 20,000 miles or 2 years. Replace annually if used in heavy traffic or dusty areas. Blocked filter reduces HVAC efficiency and can cause misting. TF, JF	20,000 miles or 2 years	£15–£30 Dealer: £30–£60
Fuel filter Manufacturer interval 40,000 miles for diesel engines. Critical for fuel injection system protection. Blocked filter can cause poor running and injector damage. TF, JF	40,000 miles or 4 years	£60–£100 Dealer: £100–£160

Periodic maintenance

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

Service item	Interval	Typical cost
Brake fluid Manufacturer interval 2 years regardless of mileage. Brake fluid absorbs moisture over time which reduces boiling point and can cause brake fade. Essential for safety. TF, JF	2 years	£60–£90 Dealer: £90–£140
Coolant flush Manufacturer interval typically 60,000 miles or 5 years. Use correct specification coolant. Old coolant becomes acidic and can corrode the radiator and water pump. TF, JF	60,000 miles or 5 years	£80–£120 Dealer: £120–£180
