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 Commercial vehicle duty cycle requires more frequent changes than passenger cars. TF_Gen1	10,000 miles or 1 year	£80–£120 Dealer: £150–£200
Fuel filter More frequent replacement required for diesel engines, especially in commercial use with varied fuel quality. TF_Gen1	20,000 miles or 2 years	£40–£80 Dealer: £80–£120
Air filter Commercial and off-road use requires more frequent replacement due to dusty conditions. Check every 10,000 miles in severe conditions. Blocked filter reduces power and increases fuel consumption. TF_Gen1	20,000 miles or 2 years	£25–£45 Dealer: £50–£80

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 Replace water pump, tensioner and idler pulleys at the same time. This is an interference engine - belt failure will cause valve damage. Critical service item for commercial reliability. TF_Gen1	80,000 miles or 5 years	£400–£600 Dealer: £700–£1000
Gearbox oil Manual transmission oil change extends bearing and synchromesh life. Use correct grade GL-4 or GL-5 as specified. Commercial use and towing accelerate oil degradation. TF_Gen1	60,000 miles or 5 years	£80–£120 Dealer: £150–£200

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 Standard 2-year interval regardless of mileage. Critical for commercial vehicle braking performance. Moisture absorption reduces boiling point and causes internal corrosion of brake components. TF_Gen1	2 years	£60–£100 Dealer: £100–£150
