Does the Lexus Nx 350 require premium gas?
Yes, the Lexus NX 350 requires premium gasoline, which is typically 91 octane or higher. This is a common requirement for many luxury and high-performance vehicles to ensure optimal engine performance and fuel efficiency.
Detailed Explanation
The Lexus NX 350 is a compact luxury crossover SUV that is powered by a turbocharged 2.4-liter four-cylinder engine. This engine is designed to operate at higher compression ratios, which helps to improve power output and fuel economy. However, this also means that the engine requires a higher-octane fuel to prevent knocking or pre-ignition, which can cause damage to the engine over time.
Most automakers recommend using premium gasoline in their high-performance or turbocharged vehicles, as the higher octane rating helps to prevent engine knock and allows the engine to operate at its optimal efficiency. This is the case with the Lexus NX 350, which is designed to run on 91 octane or higher fuel.
Consequences of Using Regular Gasoline
While it is possible to use regular gasoline in the Lexus NX 350, it is not recommended. Using a lower-octane fuel can cause the engine to experience knocking or pre-ignition, which can lead to decreased performance, reduced fuel efficiency, and potentially even engine damage over time.
In addition, using regular gasoline in a vehicle that requires premium fuel can also void the manufacturer's warranty, as it is considered a form of improper maintenance. Lexus specifically states in the owner's manual that premium gasoline is required for the NX 350 to ensure optimal performance and reliability.
Fuel Economy and Performance
Using the recommended premium gasoline in the Lexus NX 350 can also help to improve the vehicle's fuel economy and performance. The higher octane rating allows the engine to operate at higher compression ratios, which can result in increased power output and better fuel efficiency.
According to Lexus, the NX 350 is rated at 22 mpg in the city and 29 mpg on the highway when using premium gasoline. Using a lower-octane fuel could result in slightly lower fuel economy and performance numbers.
Conclusion
In summary, the Lexus NX 350 requires premium gasoline with a minimum octane rating of 91 to ensure optimal engine performance and fuel efficiency. Using a lower-octane fuel can lead to engine knock, decreased performance, and potentially even engine damage over time. It is important to follow the manufacturer's recommendations to maintain the vehicle's warranty and get the best possible driving experience.
