2018 Lexus IS maintenance schedule
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 12 months or 10,000 miles, or when the oil maintenance reminder appears, whichever comes first. 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 (same-size front/rear), a visual brake-pad/caliper/rotor check, fluid-level checks, wiper blades, driver's floor-mat check and a road test. The cabin air filter is replaced at each 10,000-mile oil service. Brake fluid and the engine air filter are replaced every 30,000 miles or 36 months. Spark plugs are replaced every 40,000 miles. The Smart Key battery is replaced every 15,000 miles or 18 months. 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 2018; other years in this range are assumed to follow it. Confirm in your owner's manual.
