As per title, how many of you guys regularly use Super Diesel (or its various counterparts) instead of the regular stuff? Reason I ask is that for the first time since I've had my diesel MK5, yesterday lunch time I ended up at a pump at the BP station that had the Super stuff and so I though what the heck might as well try it. So on the drive home, cruised on the motorway around 65-70mph and checked the average mpg when I got home and it said 67mpg! I couldn't believe it, I've only ever gotten around 60mpg thus far with some extremely conservative driving. It also felt smoother and I noticed a bit more power there (or may be that's just me). So just wanted to know anyone elses experience using this stuff. If I can get over 580ish miles on the tank, I think it may just be worth switching over from standard diesel.
