Do all Lexus cars require premium gas? Can I put regular gas in my Lexus?

Whatever kind of vehicle you drive, it is important to use the right fuel to get the best performance from your Lexus. As a premium brand, some models do need premium fuel instead of regular. You may be wondering “Can I put regular fuel in my Lexus”? Read on to find out.  

Can I Fill Up My Lexus with Regular Fuel? 

While some Lexus models require ordinary fuel, some require premium. Your Lexus car manual will tell you which kind of fuel your Lexus sedan or SUV requires for getting around Atlanta, Fayetteville and Newnan. Of course, our friendly sales associates at our Butler Lexus of South Atlanta location can help guide you on this as well.

So, saving money in the short term on gas, could cost you much more in the future.
