Does the 2021 Lexus RX 350 require premium gas?
Yes, the 2021 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 2021 Lexus RX 350 is a midsize 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 engine knocking and allows the engine to operate at higher compression ratios, resulting in improved power and fuel efficiency.
Using regular gasoline in the Lexus RX 350 may cause the engine to experience knocking or pinging, which can lead to decreased performance and potentially cause long-term damage to the engine. Lexus recommends using 91 octane or higher fuel to ensure the optimal performance and longevity of the vehicle's engine.
Fuel Economy and Performance
The use of premium gasoline in the 2021 Lexus RX 350 can also have a positive impact on the vehicle's fuel economy and performance. According to Lexus, the RX 350 with the 3.5-liter V6 engine is rated at 20 mpg in the city and 27 mpg on the highway when using premium fuel.
In terms of performance, the premium fuel helps the engine produce more power and torque, resulting in a more responsive and engaging driving experience. This is particularly noticeable during acceleration and when passing other vehicles on the highway.
Cost Considerations
The requirement to use premium gasoline in the 2021 Lexus RX 350 does come with a higher fuel cost compared to using regular unleaded. However, the potential benefits in terms of engine performance, fuel efficiency, and long-term engine health may outweigh the additional fuel costs for many owners.
Ultimately, it is important for Lexus RX 350 owners to follow the manufacturer's recommendations and use the specified premium fuel to ensure the optimal performance and longevity of their vehicle.
Is it worth putting 91 instead of 87?
Premium gas is also often called high-octane gas thanks to its octane rating of 91 to 94. Regular gas typically has an 87 rating, while the 88-90 range is considered midgrade. Premium gas drives performance in specific engines, but the idea that it's more fuel efficient is a myth.
