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.

Cabin pollen filter

Major service items

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.

Periodic maintenance
Items that don't need doing at every service but should be on your radar at the right mileage or age.

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.

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.

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.
