What kind of gas does a 2017 Lexus RX 450h take?
The 2017 Lexus RX 450h, a hybrid luxury SUV, requires premium unleaded gasoline with an octane rating of 91 or higher. This is the recommended fuel type for optimal performance and fuel efficiency in this vehicle.
Fuel Requirements for the Lexus RX 450h
The Lexus RX 450h is a hybrid vehicle that combines a gasoline engine with an electric motor. As a result, it has specific fuel requirements that differ from a traditional gasoline-powered vehicle. The manufacturer, Lexus, recommends using premium unleaded gasoline with an octane rating of 91 or higher for this model.
Using a lower octane fuel, such as regular unleaded (87 octane), is not recommended as it can lead to decreased performance, reduced fuel efficiency, and potential engine damage over time. The higher octane rating of premium fuel is necessary to prevent knocking or pinging in the engine, which can occur with lower octane fuels, especially under heavy load or high-performance driving conditions.
Reasons for the Premium Fuel Requirement
- The Lexus RX 450h's engine is designed to operate optimally with premium fuel, which has a higher resistance to premature ignition (knocking) compared to regular gasoline.
- The hybrid system, which combines the gasoline engine with an electric motor, requires the additional power and efficiency provided by premium fuel to function at its best.
- Using lower-octane fuel can result in a noticeable decrease in acceleration, power, and overall driving performance.
- Premium fuel also helps maintain the engine's long-term health and can prevent carbon buildup, which can occur with regular use of lower-octane gasoline.
It's important to always refer to the owner's manual for the specific fuel requirements of your Lexus RX 450h, as the manufacturer's recommendations should be followed to ensure optimal performance, fuel efficiency, and engine longevity.
