I will be once I get it. Only when I have plans to drive it briskly for a trackday etc, or my car is specifically mapped to higher grade ron fuel, is when I would only exclusively run the expensive shell stuff. Otherwise on a standard car I would just use the normal 95 ron. Yes you might loose a couple ponies but for normal driving it doesnt really matter and the engines are more than capable of running on the 95 ron. In some european countries thats all they have to choose from!But you may lose performance.
do you fill your Leon with 95RON then?
