If you do try it or change to using it, you need two or three tankfulls before any effect will be seen.

Momentum is the most basic standard fuel that is allowed to be sold with the addition of bio ethanol as an octane booster. Shell V power relies on much higher quality base fuels with detergents and lubricants to protect and help clean your fuel system. If your leasing and worried about fuel costs I wouldn’t bother. You need to run the car on it for a while to notice a difference. The biggest difference is when you go back and put a normal supermarket fuel back in.
