I am currently using regular (premium) unleaded fuel here in the UK. This is what it has always been filled with during it's 120K life. I believe that better performance can be achieved from using a higher octance fuel "super unleaded". Anyone got any experience with this? I am currently getting a VERY steady 24-25 mpg now matter how I drive it. Is this normal. I read on the group you could get better mpg from going up to super? Is this true?
