How much gas does a Lexus IS 250 hold?

The fuel tank capacity of a Lexus IS 250 is typically about 66–67 liters, which is roughly 17.4–17.7 US gallons, depending on the market. Exact figures can vary slightly by model year and region.


What fuel tank capacity means for drivers


Fuel tank capacity, sometimes listed as gross capacity, is the total amount of gasoline the tank can physically hold. In practice, the usable fuel is a little less because most tanks reserve a small amount of fuel to prevent the pump from running dry. Your driving range will also depend on the engine variant, transmission, and driving conditions.


Capacity by market and typical figures


The following figures reflect common official specifications for the Lexus IS 250 across major markets. Exact capacity can vary slightly by year, trim, and regional labeling.



  • US and Canada: 17.4 gallons (66 liters)

  • Europe and other regions: 66–67 liters (approximately 17.4–17.7 gallons)


These figures represent the gross tank capacity. In everyday use, you may notice the gauge showing empty before the tank is completely empty, since a reserve is kept by design for safety and reliability.


Notes on range and real-world use


Fuel economy and driving style affect how far you can go on a full tank. A typical IS 250 with its V6 engine can achieve varying miles-per-gallon depending on highway versus city driving, maintenance, and load. Always plan based on your observed fuel economy and the current gauge reading rather than the nominal tank capacity alone.


Summary


The Lexus IS 250 generally carries about 66–67 liters (roughly 17.4–17.7 US gallons) of fuel in its tank. While this is the official capacity, the usable amount is slightly less due to reserve space. For planning, use the gross capacity as a baseline and factor in your vehicle’s actual fuel economy and driving conditions.

Is the Lexus IS 250 a fast car?


No, the IS250 is not considered fast, but it is a responsive and capable car for daily driving. It has a 0-60 mph time of around 7.6 to 8.4 seconds, making it slower than many other luxury or performance-oriented cars on the market. The engine can feel weak under stress, like going uphill, due to a lack of low-end torque.

That said, fuel mileage isn't bad, at an EPA-rated 21 mpg city, 29 mpg highway. Inside, the IS 250 is comfortable up front, a little cramped in the rear.



Does a Lexus IS 250 need premium gas?


Yes, the Lexus IS250 recommends premium unleaded gasoline (91 octane or higher) for optimal performance and to prevent engine knocking. While using a lower-octane fuel like regular 87 octane won't cause immediate, catastrophic damage, it may lead to engine knocking and reduced performance over time, and can contribute to faster carbon buildup on engine parts. 
Recommended action

  • Use premium gasoline: For the best engine performance, efficiency, and longevity, use 91 octane or higher. 
  • Use regular sparingly: If you must use 87 octane, it's best to do so only in a pinch and to return to premium as soon as possible to avoid potential issues. 
  • Be aware of performance impact: The engine computer will adjust, but you may notice reduced performance when using lower-octane fuel. 
  • Prevent long-term damage: Consistent use of lower-octane fuel can lead to persistent engine knocking, which can cause long-term engine damage. 



How many gallons does a Lexus IS 250 hold?


The Lexus IS250 fuel tank capacity is typically between 17.1 and 17.4 gallons depending on the model year.
