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 Lexus recommends 10,000 miles or 12 months. Use 5W-30 fully synthetic oil. Change oil and filter together - never just oil alone. XU10	10,000 miles or 1 year	£80–£120 Dealer: £140–£200
Air filter Replace more frequently in dusty conditions. Dirty filter reduces performance and increases fuel consumption. XU10	30,000 miles	£25–£40 Dealer: £40–£70
Cabin pollen filter Located behind glove compartment. Blocked filter causes poor heating and air conditioning performance. XU10	20,000 miles or 2 years	£30–£50 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 and water pump Interference engine - belt failure causes valve damage. Replace water pump, tensioner, and idler pulley at same time. Failure to replace on schedule risks £3000+ engine damage. XU10	60,000 miles or 5 years	£400–£600 Dealer: £700–£1000
Automatic transmission fluid Toyota states lifetime fill but specialists recommend 60k changes. Use Toyota Type T-IV or WS fluid only. Drain and refill method preferred over flush. XU10	60,000 miles	£120–£180 Dealer: £200–£300

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 Use platinum plugs. V6 engine requires six plugs. Replace all together for even performance. XU10	60,000 miles	£80–£120 Dealer: £150–£220
Brake fluid Two year interval regardless of mileage. Brake fluid absorbs moisture which reduces braking efficiency and causes corrosion. XU10	2 years	£60–£90 Dealer: £100–£150
Coolant flush Use Toyota red coolant or equivalent. System capacity approximately 8 litres. Flush prevents corrosion of aluminium components. XU10	100,000 miles or 10 years	£80–£120 Dealer: £140–£200
