Why does the Lexus NX 300 require premium gas?
The Lexus NX 300 is a luxury compact crossover SUV that requires the use of premium gasoline, typically 91 octane or higher. This is due to the engine's design and performance specifications, which are optimized for higher-octane fuel.
Engine Design and Performance
The Lexus NX 300 is powered by a 2.4-liter turbocharged four-cylinder engine that produces 235 horsepower and 258 lb-ft of torque. This engine is designed to operate at higher compression ratios and utilize advanced technologies like direct fuel injection and turbocharging to deliver enhanced performance.
To prevent knocking or pre-ignition, which can cause engine damage, the Lexus NX 300's engine requires the use of premium gasoline with a higher octane rating. The higher octane fuel is less prone to premature ignition, allowing the engine to operate at its optimal performance level.
Fuel Efficiency and Emissions
