Can I Use Regular Fuel in a Lexus? 

We recommend always using the minimum octane rating or higher when refueling your vehicle. Choosing an octane rating lower than what is listed for your model year vehicle could lead to engine knocking, which can result in permeant damage to your engine in the long run. Using the wrong fuel for your Lexus can also void your vehicle’s warranty, ultimately costing you more than the money saved at the pump in the long run. 

Should You Use a Higher Octane Than Recommended? 

Choosing a higher-octane fuel than recommended won’t hurt your car, but it won’t help either. Premium gas engines often have high compression ratios or turbochargers. Regular gas engines don’t have the necessary components needed to reap the performance and efficiency benefits associated with premium fuel. At a cost of about fifty cents more per gallon, why pay for premium gas you don’t need?
