Yes, the Lexus LS 460 does require premium fuel. Using regular gas in a Lexus LS 460 can lead to decreased power and performance over time, and it may even cause engine damage. Most Lexus models, including the LS 460, require premium gas with an octane rating of at least 91.
While some sources suggest that using regular gas in a Lexus LS 460 may not cause immediate harm due to the engine’s ability to adjust to lower octane levels using antiknock sensors , it is still recommended to use premium fuel to ensure optimal performance and avoid potential long-term damage to the engine.
It’s important to note that if the vehicle’s manual states that premium gas is required, it is best to follow that recommendation to maintain the warranty and avoid any potential issues.
