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 Morgan specialists recommend 6-month/6,000-mile intervals due to infrequent use patterns typical of these cars. S4, S5	6,000 miles or 6 months	£80–£120 Dealer: £150–£220
Air filter Standard Ford interval. Check more frequently if driven in dusty conditions. Restricted air filter reduces performance and increases fuel consumption on naturally aspirated engines. S4, S5	20,000 miles or 2 years	£25–£45 Dealer: £45–£70

Major service items

These are the big-ticket items. Miss them and you risk engine or gearbox damage. The costs are higher but the consequences of skipping are much worse.

Service item	Interval	Typical cost
Timing belt Ford timing belt interval typically 60,000 miles or 5 years. S4, S5	60,000 miles or 5 years	£350–£500 Dealer: £600–£800

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
Spark plugs Standard interval for Ford engines. Use manufacturer-specified heat range. Gap checking essential on older engines. Misfiring from worn plugs affects catalyst life and emissions compliance. S4, S5	20,000 miles or 2 years	£60–£100 Dealer: £100–£150
Brake fluid 2-year interval regardless of mileage due to moisture absorption. S4, S5	2 years	£60–£90 Dealer: £100–£140
Coolant flush Ford recommended interval varies by coolant type. S4, S5	60,000 miles or 5 years	£120–£180 Dealer: £200–£280
