I agree. This is the key I feel to better mpg with the higher octane fuel. A driving instructor pall of mine calls it the ‘head down arse up’ style of driving where, the individual darts around like a demented housefly with little cognisance or awareness of what is in front, to the side or behind them. They simply react to the immediate situation instead of planning ahead and interpreting the hazards well in advance. The result is short sharp blasts on both the accelerator and brake peddles. They are also usually the ones tailgating the car in front cos they are very, very late for everything or want to be doing 90 every where they go. By adapting a more forward thinking approach and better planning, you will not only prolong your own life, that of the car and it’s consumable components. But also improve fuel economy.

My theory in relation to the benefit of using V-pwr is that with 95 Ron you subconsciously settle in to a comfortable driving style which amongst other things requires a certain amount of pressure on the accelerator in order to achieve the requires amount of acceleration/speed. This will of course be different and fairly unique to each individual depending on a wide and complicated set of parameters. However with the 97 or 98 Ron fuel, the car is more responsive, accelerates more quickly and runs better so therefore you feel the acceleration and desired speed much earlier without the need to apply the same amount of pressure over the same time span. lLess imput means less consumption. Therefore I have concluded that it is not the fuel per say that gives the improved economy but the combination of better performance and a slight subconscious change in your driving style as a result.



Scientifically the higher octane fuel is better in terms of combustibility which the engine will harness to produce more power on a ltr for ltr basis and consequentially offer better acceleration per psi of pressure on the accelerator.

You may disagree with this but having tried shell v-pwr and spent some time thinking about the results, these are just some of my thoughts on the subject. Afterall no two cars are exactly the same, just as no two people on this earth are exactly the same and no two journeys are exactly the same etc, etc, etc……. In my very humble opinion, if you like V-pwr or the other commercially available equivalents then use it. If not, then don’t. It’s your individual choice and no one else’s opinion including mine matters jot. Each to their own.
