Does a Lexus 460 need premium gas?
As a proud owner of a Lexus 460, you may wonder about the type of fuel that best suits your vehicle. With years of experience in car maintenance and repair, I can provide you with insights into whether premium gas is necessary for your Lexus 460 and the implications of your fuel choice.
Understanding Fuel Requirements

In summary, while the Lexus 460 can run on regular gasoline, it is highly advisable to use premium fuel to ensure optimal performance, efficiency, and engine health. Investing in the right fuel will not only enhance your driving experience but also prolong the life of your vehicle.
