More fuel economy

Higher octane fuel is able to burn at a more optimum temperature and for longer than standard fuels, therefore generating the power required by the driver. As a result less fuel is required to achieve higher levels of power. Lower octane fuel requires the car to work harder, using more fuel to achieve the power demanded by the driver therefore increasing overall fuel consumption.

Tesco 99 octane was independantly tested on fuel economy against standard petrol (95 octane), by Thorney Motorsport.

Cleaner & greener

An enhanced additive package;
To remove existing deposits and help the engine to run more smoothly, Tesco 99 Octane contains an enhanced additive package with twice the protective power of typical 95 octane fuel.

And cleaner inside;
Tesco 99 Octane contains low levels of olefinic compounds which can lead to the creation of deposits - typically less than 5%, compared with up to 18% in standard petrols. So it's less likely than standard petrols to create engine deposits in the first place.

With biofuel too;
Tesco 99 Octane contains bioethanol – a renewable component with 135 octane. So if you are choosing a super fuel, you can still do a little bit for the environment.
