Does the 2020 Lexus RX 350 require premium gas?
Yes, the 2020 Lexus RX 350 requires premium gasoline, specifically 91 octane or higher. This is a common requirement for many luxury vehicles, as the higher-octane fuel helps optimize the engine's performance and efficiency.
Detailed Explanation
The 2020 Lexus RX 350 is a mid-size luxury SUV that is powered by a 3.5-liter V6 engine. This engine is designed to run on premium gasoline, which has a higher octane rating than regular unleaded fuel. The higher octane rating helps prevent premature ignition, or "knocking," which can cause engine damage over time.
Using regular gasoline in a vehicle that requires premium can result in reduced power, decreased fuel efficiency, and potentially long-term engine issues. Lexus specifically recommends using 91 octane or higher fuel for the best performance and longevity of the RX 350's engine.
Consequences of Using Regular Gasoline
While it is possible to use regular gasoline in the 2020 Lexus RX 350, it is not recommended by the manufacturer. Some of the potential consequences of using regular fuel include:
- Reduced horsepower and acceleration
- Decreased fuel efficiency, leading to higher fuel costs
- Increased risk of engine knocking or pinging, which can cause long-term damage
- Potential for the engine to run less smoothly or experience misfiring
To avoid these issues and maintain the optimal performance of the RX 350, Lexus strongly advises using premium gasoline with a minimum octane rating of 91.
Conclusion
In summary, the 2020 Lexus RX 350 requires premium gasoline with a minimum octane rating of 91. Using regular gasoline can result in reduced power, decreased fuel efficiency, and potential engine damage over time. To ensure the best performance and longevity of your RX 350, it is recommended to always fill up with premium fuel as specified by the manufacturer.
Can you mix premium and regular gas?
There's nothing wrong with mixing premium and regular gas in the same tank. In fact, this is how midgrade gas is formulated at the station. Rather than drawing from a separate storage tank for each octane rating, gas pumps actively mix high-octane fuel with lower-octane fuel to create midgrade gas.
