Hi peeps. I not long ago bought a 58 plate A4 s-line 1.8T (160). The car is great (still miss my A3 2.0 TDI though). I was recently thinking of running it on v power but I understand you have to run 3 tank fills of the stuff before you notice a difference. I was wondering do you actually notice a difference? I would hate to go through 3 tanks of the stuff only to find no difference. Not to sure would the 1.8T benefit from it either. I was also reading somewhere that once the ecu adapts to this fuel and if you go back to regular unleaded the car would run like a bag of spanners. Can anyone on here persuade me to convert to v power or should I just save the extra pennies and buy a few lottery tickets instead?
