The Lexus IS 300 engine is known for its durability and longevity, with many owners reporting their engines lasting well over 200,000 miles with proper maintenance. The IS 300's 3.0-liter inline-six engine is a robust and reliable powerplant that can provide years of dependable service if cared for correctly.


Factors Affecting IS 300 Engine Lifespan

  • Driving Conditions - Engines that are subjected to heavy towing, frequent high-speed driving, or other extreme conditions may wear out faster than those used for more moderate, everyday driving.

  • Modifications - Significant engine modifications, such as forced induction or high-performance upgrades, can put additional stress on the engine and reduce its lifespan if not done properly.

  • Owner Care - Owners who treat their vehicles gently, avoid excessive idling, and address any issues promptly tend to get the most longevity out of their IS 300 engines.


With proper care and maintenance, many IS 300 owners report their engines lasting 200,000 miles or more. However, individual results may vary depending on the factors mentioned above.

  • Change the engine oil and filter at the recommended intervals, typically every 5,000 to 7,500 miles.

  • Perform regular tune-ups, including replacing spark plugs and other wear items as needed.

  • Address any issues, such as leaks or unusual noises, promptly to prevent further damage.

  • Avoid excessive idling, towing heavy loads, or other extreme driving conditions whenever possible.
