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 specifies 10,000 miles or 12 months. Use 0W-20 synthetic oil as specified. Change filter every service. Missing oil changes can accelerate timing chain wear on these engines. XU30, AL10	10,000 miles or 1 year	£80–£120 Dealer: £150–£220
Air filter Replace every 30,000 miles. Check more frequently in dusty conditions. Dirty filter affects fuel economy and engine performance. XU30, AL10	30,000 miles or 3 years	£25–£40 Dealer: £40–£70
Cabin pollen filter Replace every 15,000 miles or 24 months. More frequent replacement needed in urban areas. Blocked filter reduces air conditioning efficiency and causes musty odours. XU30, AL10	15,000 miles or 2 years	£20–£35 Dealer: £35–£60

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
Automatic transmission fluid Lexus claims lifetime fluid but specialists recommend change at 60,000 miles. Use Toyota WS transmission fluid only. Old fluid causes harsh shifting and transmission wear. XU30, AL10	60,000 miles or 6 years	£200–£300 Dealer: £350–£500

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 Replace every 60,000 miles. Use genuine iridium plugs as specified. Worn plugs cause misfiring and catalyst damage. Check ignition coils at the same time. XU30, AL10	60,000 miles or 6 years	£150–£250 Dealer: £250–£400
Brake fluid Replace every 2 years regardless of mileage. Brake fluid absorbs moisture which reduces braking performance and corrodes internal brake components. Use DOT 3 or DOT 4 as specified. XU30, AL10	2 years	£60–£90 Dealer: £100–£150
Coolant flush First change at 100,000 miles or 10 years, then every 50,000 miles or 5 years. Use Toyota Long Life Coolant. Old coolant causes water pump and radiator corrosion. XU30, AL10	100,000 miles or 10 years	£80–£120 Dealer: £150–£220
