I was told something that interested me recently. My local garage man said when I told him that I didnt get any improvement in consumption on my Yaris T sport when using vpower (48.3 mpg at the mo) was that because as Vpower only increases the torque/power output the only benefit I would get would be a bit more get up and go. As I drive as economically as it is possible (changing up at 2-3000) and staying in top (20mph per thousand) even around round-a-bouts, yes the yaris is very happy to oblidge (goes everywhere in top) apparently you cannot improve on its best effort and will only find improvement if you dont already drive in the manner discribed. He did say that running a couple of tanks through every few thousand is beneficial to the fuel system, but otherwise I would just be boosting shells profits. I must say I didnt notice any improvement to the smoothness or lack of in the slightly rough yaris. (Still miss the A2 '1.4 petrols' refinement) I know Im talking petrol here but suspect the same applies to derv. Hope this helps to those who have not got the improvment you hoped for when changing to Vpower, the good news is you are driving to the best of your cars ability. Cheers Colin
