Does the 2024 Lexus RX 350h require premium gas?
Yes, the 2024 Lexus RX 350h hybrid SUV requires premium gasoline, according to the manufacturer's recommendations. This high-end luxury vehicle is designed to operate optimally with 91 octane or higher fuel.
Detailed Explanation
The 2024 Lexus RX 350h is a hybrid version of the popular RX midsize luxury SUV. It combines a 2.5-liter four-cylinder gasoline engine with an electric motor to provide a balance of power and efficiency. Lexus specifically states in the owner's manual that this hybrid model requires the use of premium unleaded gasoline with a minimum octane rating of 91.,
Using regular 87 octane fuel in the RX 350h is not recommended, as it could lead to reduced performance, decreased fuel economy, and potential engine damage over time. The higher-octane premium fuel is necessary to prevent knocking or pinging in the engine, which can occur with lower-octane regular gas.,
The premium fuel requirement is common for many luxury and performance-oriented vehicles, as the engines are designed to operate most efficiently with higher-octane gasoline. This allows for features like higher compression ratios, turbochargers, or hybrid systems to function as intended without risk of premature ignition or other issues.p>
Fuel Economy and Cost Considerations
While the premium fuel requirement may result in slightly higher fuel costs, the 2024 Lexus RX 350h is still expected to deliver excellent fuel economy for a midsize luxury SUV. The EPA estimates it will achieve 36 mpg in city driving and 33 mpg on the highway, with a combined rating of 35 mpg.
Owners will need to factor in the premium fuel costs when budgeting for the RX 350h's operating expenses, but the hybrid powertrain's efficiency should help offset some of those higher fuel expenses compared to a non-hybrid model. Overall, the premium fuel requirement is a trade-off for the RX 350h's performance and efficiency capabilities.
