Frequently Asked Questions
Does the Lexus RX300 need premium gas?
You can put premium gas in your Lexus RX, and it can provide better performance, but it's not a requirement. Any gas that's put in your Lexus RX shouldn't be higher than 15% ethanol. If gasoline at the pump has more than 15% ethanol, or it's labeled as a flex-fuel, it shouldn't be used in your RX.
What happens if you accidentally put 87 instead of 91 in a Lexus?
Use of unleaded gasoline with an octane rating lower than what is listed for your model year vehicle could potentially result in engine knocking. If the octane rating used is less than required, damage to the engine may occur and which could void the vehicle warranty.

Does Premium Fuel Make Your Car Run Better? Some drivers swear that using a higher-octane fuel is better for a car's performance, but it's not.
