Lexus Gs300 service: key facts

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 itemIntervalTypical cost
Engine oil and filter
Manufacturer specifies 10,000 miles or 12 months. Use 0W-20 oil for S190 generation, 5W-30 for S147. Missing this service voids warranty and accelerates engine wear.

 10,000 miles or 1 year
£80–£120
Dealer: £180–£250
Air filter
Replace every 30,000 miles or 3 years. Clogged filter reduces performance and increases fuel consumption. Check more frequently in dusty conditions.

Dealer: £50–£80
Cabin pollen filter

Periodic maintenance

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

Service itemIntervalTypical cost
Spark plugs
Replace every 60,000 miles or 6 years. Use iridium or platinum plugs as specified. Worn plugs cause misfiring, poor fuel economy, and emission failures.
S147, S190
 60,000 miles or 6 years
£120–£180
Dealer: £200–£300
Brake fluid
Replace every 2 years regardless of mileage. Brake fluid absorbs moisture which reduces boiling point and can cause brake fade or system corrosion.
S147, S190
 2 years
£60–£90
Dealer: £120–£180
Coolant flush
Replace every 100,000 miles or 10 years. Use Toyota Long Life Coolant only. Old coolant loses anti-corrosion properties and can cause radiator or water pump failure.
S147, S190
 100,000 miles or 10 years
£90–£140
Dealer: £180–£250
