Well as most of you will know I am a Fiat DET and was keen to be able to give proper advice to my customers regarding V power diesel, it just happened to be an almost empty tank occurred on Saturday so my Stilo was completely filled (53 litres). I can confirm that there is no drop in fuel economy, possibly a few more mpg but as the tank is still being used I will let you guys know later. One thing that was very obvious was the engine very quickly picked up smoother and the engine was more responsive. Idle speed remained smooth, smoke wise I havent driven her at night to really see the smoke, but nothing noticeable during the day. At 102.9 its not cheap (standard diesel is 94.9) but I think I would recommend it for either alternate fills or 1 in 3 refills. Certainly it may have different benefits for engines at different mileages, my mileage 20k, and I would expect it more difficult for a tight engine to notice any difference, where as a it may be more onvious to a looser engine. Highly recommended, but dont take my word for it try it yourself.
