Does Lexus 450h really need premium gas?

Does the Lexus RX 450h Require Premium Gas?
The Lexus RX 450h is designed to run on premium gasoline, as indicated in the owner’s manual. While it is possible to use mid-range or “Plus” gas (89 octane) without immediate noticeable performance deterioration, it’s important to note that using a lower octane fuel than recommended may lead to potential long-term damage to the engine.
It’s worth noting that the RX 450h requires premium gasoline with an octane rating of 91 (Research Octane Number 96) or higher, as stated in the owner’s manual. While it’s true that using premium gas can be more expensive, it’s essential for maintaining the optimal performance and longevity of the vehicle.
In summary, while the Lexus RX 450h may not experience immediate issues when using lower octane fuel, it is designed to run on premium gasoline for optimal performance and to prevent potential long-term damage to the engine.
