Hi All,
How often do you use super unleaded fuel on your s5 or a5?
I understand it supposedly is good to clean out your engine now and then, I have been told it's good to do this once a month, currently I am just running normal unleaded as it is recommended in the fuel cap.
Anyone notice it has improved your mpg and any other benefits?
Many thanks.
