What oil does a 1998 Lexus GS300 take?


When it comes to maintaining your 1998 Lexus GS300, choosing the right oil is crucial for ensuring optimal engine performance and longevity. As a seasoned auto service provider, I’ve worked on countless vehicles, including the Lexus GS300, and I’m here to guide you through the specifics of selecting the correct oil for this classic luxury sedan.


Recommended Oil Type for the 1998 Lexus GS300


The 1998 Lexus GS300 is equipped with a 3.0-liter inline-6 engine, known for its smooth performance and reliability. For this engine, Lexus recommends using:



  • Oil Type: SAE 5W-30 motor oil

  • Oil Specification: Ensure the oil meets or exceeds API (American Petroleum Institute) certification standards, such as API SN or newer.


SAE 5W-30 is ideal because it provides excellent viscosity in both cold and hot temperatures, ensuring proper lubrication during engine startup and under high operating temperatures.


Conventional vs. Synthetic Oil


When choosing between conventional and synthetic oil, consider the following:



  • Conventional Oil: This is the traditional choice and is generally more affordable. It works well for older engines like the one in the 1998 Lexus GS300, especially if the car has been consistently maintained with conventional oil.

  • Synthetic Oil: Offers superior performance, especially in extreme temperatures. It provides better engine protection, reduces wear, and can extend the time between oil changes. If your GS300 has been switched to synthetic oil in the past, it’s a great option to continue using.


Both options are suitable, but synthetic oil is often recommended for drivers who want enhanced engine protection and performance.


Oil Capacity and Change Interval


In addition to selecting the right oil type, it’s important to know the oil capacity and recommended change intervals:



  • Oil Capacity: The 1998 Lexus GS300 requires approximately 5.4 quarts (5.1 liters) of oil, including the oil filter.

  • Change Interval: For conventional oil, change it every 3,000 to 5,000 miles. For synthetic oil, you can extend the interval to 7,500 to 10,000 miles, depending on driving conditions and habits.


Additional Tips for Maintaining Your Lexus GS300


To keep your 1998 Lexus GS300 running smoothly, follow these additional maintenance tips:



  • Always use a high-quality oil filter to ensure proper filtration and prevent contaminants from circulating in the engine.

  • Check your oil level regularly and top it off if necessary, especially before long trips.

  • Inspect for oil leaks around the engine and address them promptly to avoid damage.

  • Stick to a consistent maintenance schedule to prolong the life of your vehicle.


By using the correct oil and following these maintenance tips, you can ensure that your 1998 Lexus GS300 continues to deliver the reliable performance it’s known for.
