Which Fuel Grade Should I Use for My Lexus IS 250? Explained Octane Levels & Premium Gas
When it comes to fueling your Lexus IS 250, one question that often arises is, “Which fuel grade should I use?” The answer lies in understanding the octane levels and the importance of using premium gas for your Lexus.
Lexus IS 250 Gas Type
The Lexus IS 250 is a luxury sedan that requires the use of 91 octane (premium) gasoline. But why is this the case?
Why Does Lexus IS 250 Require Premium Gas?
The Lexus IS 250 engine is designed to perform optimally with premium gas. The higher octane rating of premium gas (typically 91 or higher) helps prevent knocking and provides better engine performance.
Benefits of Using Premium Gas
Using premium gas offers several benefits for your Lexus IS 250:
Improved Engine Performance
Premium gas provides a cleaner burn and allows the engine to operate more efficiently, resulting in improved power and performance.
Optimal Fuel Efficiency
Premium gas also helps improve fuel economy. The higher octane rating provides better combustion, leading to better gas mileage and decreased fuel consumption.
Overall, by using premium gas, you can ensure that your Lexus IS 250 operates at its best, delivering outstanding performance and fuel efficiency.

Types of Fuel Grades
When it comes to fueling your Lexus IS 250, it is important to understand the different types of fuel grades available. The two main types of fuel grades are regular and premium gas, which have different octane levels.
What is Octane?
Octane is a unit of measurement used to determine the anti-knock properties of fuel. It indicates the fuel’s ability to resist premature combustion, also known as knocking, which can damage the engine.
Fuel Grade Recommendations for Lexus IS 250
The Lexus IS 250 requires the use of premium gas with a minimum octane rating of 91. This is because the engine is designed to perform optimally with higher octane fuel. Using regular gas with a lower octane rating may result in reduced performance and potential engine damage.
Octane Levels and Performance
The octane level of fuel directly impacts the performance of your Lexus IS 250. Premium gas with a higher octane rating provides better engine performance by preventing knocking and allowing the engine to operate more efficiently.
Impacts of Using Lower Octane Fuel
Using lower octane fuel, such as regular gas with an octane rating of 87, in a Lexus IS 250 can have several negative impacts. It may lead to reduced engine performance, decreased fuel efficiency, and potential engine knocking. Therefore, it is crucial to follow the manufacturer’s recommendations and use the recommended fuel grade.
Choosing the Right Gasoline
When it comes to fueling your Lexus IS 250, it is essential to choose the right gasoline that meets the requirements of your vehicle. The two main options to consider are regular unleaded gasoline and premium unleaded gasoline.
Regular Unleaded Gasoline (87 Octane)
Regular unleaded gasoline, with an octane rating of 87, is the standard fuel option available. It is suitable for most vehicles and provides sufficient performance for everyday driving. However, it is important to note that the Lexus IS 250 requires the use of premium unleaded gasoline.
Premium Unleaded Gasoline
Premium unleaded gasoline, typically with an octane rating of 91 or higher, is the recommended fuel for the Lexus IS 250. This higher octane rating helps prevent knocking, which can occur when the air-fuel mixture ignites prematurely in the engine. By using premium gasoline, you can ensure optimal engine performance and protect against potential damage.
Factors to Consider
When deciding between regular and premium gasoline for your Lexus IS 250, there are a few factors to consider. Firstly, the engine of the IS 250 is designed to perform optimally with higher octane fuel.
Using regular unleaded gasoline with a lower octane rating may result in reduced performance and can potentially lead to knocking.
Additionally, using premium unleaded gasoline can provide benefits such as improved engine performance and fuel efficiency. Premium gas allows for a cleaner burn and better combustion, resulting in increased power and better gas mileage.
Cost Considerations
One aspect to keep in mind is the cost difference between regular and premium gasoline. Premium unleaded gasoline is typically more expensive per gallon compared to regular unleaded gasoline. However, the improved fuel efficiency and overall performance can offset the higher cost in the long run.
It is essential to weigh the potential benefits against the additional expense to determine if using premium gasoline is the right choice for you and your Lexus IS 250.
Long-Term Engine Health
Using the recommended premium unleaded gasoline for your Lexus IS 250 can contribute to the long-term health and longevity of your engine. The higher octane rating helps protect against knocking, which can lead to engine damage over time.
By using premium gasoline, you can ensure that your Lexus IS 250 operates at its best, promoting optimal engine health and performance.
