Does the Lexus RX 450h require premium gas?
Yes, the Lexus RX 450h hybrid SUV requires premium gasoline, typically 91 octane or higher. This is a common requirement for many luxury and high-performance vehicles, including the Lexus RX 450h, to ensure optimal engine performance and fuel efficiency.
Detailed Explanation
The Lexus RX 450h is a hybrid electric vehicle that combines a gasoline engine with an electric motor. This advanced powertrain requires the use of premium fuel to function at its best. The engine in the RX 450h is designed to take advantage of the higher octane rating of premium gasoline, which helps prevent knocking or pinging during combustion.
Using regular gasoline in the Lexus RX 450h can result in decreased power, reduced fuel economy, and potentially even engine damage over time. Lexus recommends that owners always fill their RX 450h with premium fuel to ensure the vehicle runs at its optimal performance level and to protect the long-term health of the engine.
Reasons for Premium Fuel Requirement
- Higher compression ratio in the engine, which requires higher octane fuel to prevent knocking
- Improved engine performance and efficiency with premium fuel
- Reduced risk of engine damage or decreased lifespan when using lower-octane regular gasoline
- Compliance with Lexus' warranty and maintenance requirements
