Not quite.
They ALL have a bio-content.
Its the other additives that make a difference.
Supermarket fuel has JUST enough additives to meet the BS spec.
Branded fuel MAY have more additives to exceed the BS spec.
And the super fuels like Ultmate etc PROBABLY have even more additives.
And don't forget the Shell Formula fiasco ! 9 out of 10 people said it was crap, it was only when Police forces threatened to sue that Shell started listening.
