I have had several customers call me about what to do for fuel during the shortage here in Atlanta. Many of our local gas station are out of everything but Regular Grade.
According to the owner’s manual, you may use Regular Grade fuel in your vehicle if the higher grades are unavailable. However, you need to change how you are driving. It is recommended you do not accelerate quickly and do not exceed 3000 RPM. If you can, put in less than half a tank and add Premium Grade back as soon as possible. We are not recommending that you put Regular Grade in an AMG vehicle.
