I am going through my first tank of Shell V-power diesel at the moment. I have posted on another thread about it - basically, thought car was smoother under acceleration, a little more perky, noticeably quieter and cut the amount of exhaust amoke down considerably. At a cost of £3 more a tank, wasn't sure if it was worth it .....
Now that I have used just over half the tank, something has happened to the economy of the car. On normal diesel with some Millers, my run hom from work will average out at 46 - 47mpg. Tonight, I got an average of 52mpg, which I thought was quite staggering! I got stuck in heavy traffic and razzed it a few times up to 4k rpm!
If the economy continues, then this fuel is worth it. ....
