Gas Type for Lexus RX 450h
The Lexus RX 450h is recommended to use reformulated gasoline. This recommendation applies to all Lexus vehicles, including the RX450h and RX350, and is stated in the owner’s manuals for these vehicles. The use of reformulated gasoline is not expected to negatively affect the engine or decrease its performance. Additionally, Lexus recommends the use of unleaded gasoline with an octane rating of 87 or higher, which means the Lexus RX 450h does not require premium gasoline, as the premium octane rating is 91 or higher. However, using higher-quality gasoline can help improve the car’s performance and fuel efficiency. It’s worth noting that any gasoline used in the RX should not contain more than 15% ethanol [[9]].
In summary, the Lexus RX 450h is designed to work with a range of gasoline grades, from regular to premium. While there is no requirement to use premium gasoline, using higher-quality gasoline can enhance the car’s performance and fuel efficiency.
