What happens if you put regular gas in a Lexus GX 460?

If you put regular gas in a Lexus GX 460, it may have some negative effects on the engine and performance of the vehicle. The Lexus GX 460 is designed to run on premium gas with an octane rating of 91 or higher. Using regular gas, which has a lower octane rating, can increase the chances of uncontrolled self-combustion, leading to engine knocking. Engine knocking can cause damage to the engine and may result in reduced performance and fuel efficiency. Additionally, the engine control unit (ECU) in the GX 460 is programmed to optimize performance with higher octane fuel, and using regular gas may cause the ECU to pull timing and reduce engine power.
It is important to follow the manufacturer’s recommendations and use the specified octane rating for your Lexus GX 460 to ensure optimal performance and avoid potential engine damage.
