Buying performance fuels are for performance cars, not your every day run of the mill.
If you think you get more miles, then think how much more it cost you.
It's only needed for high performance engines. Other than that its just a placebo effect as you think your putting in something better cause it costs more
Do not agree, I've used supermarket diesel, and tried a tank full of shell v power and found noticeable difference.
Car warms up quicker
Engines runs sweeter
And a few more miles to the gallon
And because the cost of fuel is low at the moment it's worth trying it for yourself.
