a 7% price increase for a 1% quicker 0-60 on that specific occasion, just save the few extra quid per fill up.
That's impressive but doesn't prove anything unless you do the same journey at the same speeds using normal 95RON petrol.Just to put a different spin on this. I was travelling home from a car meet last night and decided to see what the car would average if I drove economically....
So I drove at 60 on the motorway (I refuse to go slower) and then the same on the a13 into London, then at the speed limits while using the gear change indicator.
68.9mpg on VPower.
The thing is here that pretty much any modern car will react to a higher octane fuel in the appropriate way due to the amount of sensors on it. So when it feels the different knock from the fuel it will adjust timing to suit and use that extra octane in the form of a more efficienct burn which should give you more mpg and power.
I always thought British petrol was better quality than the continental stuff. They have a habit of mixing their petrol with ethanol which they get from fermenting turnips and grains. It probably wouldn't do any harm but I'd rather use proper petrol in my Up!Petrol in the UK is not fantastic quality. The petrol in Germany is more refined. The one leatre engine that is in the UP! is built around using this petrol so if you are very concerned about it then I would just use super unleaded, as for the brand it doesn't really matter, the only thing it will really effect is the emissions and a little bit of the performance
