2023 Lexus GX maintenance schedule

Applies to: 4.6L V8 (1UR-FE) GX 460, full-time 4WD; severe-only and optional active-height-control items are marked

Schedule type: fixed

Lexus sets a service visit every 6 months or 5,000 miles, whichever comes first. Replace the engine oil (0W-20) and filter every 10,000 miles (at the 12-month visits in the log), or when the maintenance reminder light is due with the oil service. If 0W-20 is not available, 5W-20 may be used but must be replaced with 0W-20 at the next oil change. Every visit covers tire rotation, a brake drum/pad/disc inspection, fluid-level checks, wiper blades, driver's floor-mat check and a road test. At 15,000-mile visits the guide also lubricates the drive shaft, re-torques its nuts and bolts, tightens propeller shaft bolts and replaces the Smart Key battery. Cabin air filter, brake fluid and engine air filter are replaced every 30,000 miles or 36 months. Spark plugs are replaced at 120,000 miles. Summarized in our own words from the source listed. Always follow the owner's manual or your dealer for your specific vehicle (VIN, engine, and options).

Checked against the official document for model year 2023; other years in this range are assumed to follow it. Confirm in your owner's manual.
