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 6,000 miles or 6 months. ZX	6,000 miles or 6 months	£45–£65
Air filter Manufacturer interval 12,000 miles or annually. Check more frequently in dusty conditions. Clogged filter affects performance and fuel economy on these engines. ZX	12,000 miles or 1 year	£15–£25
Fuel filter Manufacturer interval 12,000 miles or annually for diesel variants. Critical for injection pump protection. Water drain and prime system after replacement. ZX	12,000 miles or 1 year	£35–£55

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 Manufacturer interval 36,000 miles or 4 years, whichever comes first. These are interference engines - belt failure causes valve damage. Replace tensioner and water pump at same time. ZX	36,000 miles or 4 years	£280–£400

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. Critical for brake performance and component longevity. Flush entire system including rear cylinders. ZX	2 years	£45–£65
Coolant flush Manufacturer interval 36,000 miles or 4 years. Use correct antifreeze specification to prevent corrosion in aluminium components. Check thermostat operation during flush. ZX	36,000 miles or 4 years	£65–£95
