Can I use regular gas in my Lexus RX 450H?
You must only use unleaded gasoline in the RX, with an octane rating of 87 or higher. This means the Lexus RX does not require premium gasoline, as the premium octane rating is 91 or higher. Of course, you are free to put premium gas in your Lexus RX, as it can provide better performance, but it is not needed.
When your car needs a higher-octane gasoline, it means that the fuel can better resist the unwanted combustions that happen when the air and fuel mix in your engine. If you have a higher-performance vehicle, like a Lexus NX, premium gasoline is typically recommended since the engine is specifically designed for it.
If you want to continue to enjoy the outstanding power and high-level efficiency offered in new Lexus models, you’ll want to utilize the recommended Lexus gas type. Some Lexus vehicles will require premium 91-octane fuel while others can use regular 87-octane fuel.
What happens if I accidentally put regular gas in my Lexus?
Lexus requires that the minimum gas octane rating be 91, which is premium gas. All Lexus coupes, which are high-performance cars, require high octane premium gas. The engines of these cars run with a high compression ratio to generate more power. Using regular gas will lead to knocking, which results in engine damages.
