Title sponsors of the Tesco 99 Octane MSA British Rally Championship for the 2008 and 2009 seasons.

Tesco 99 Octane unleaded petrol is made up of a specially formulated mix of high quality petrol components carefully blended to achieve higher octane and uniquely low levels of the deposit forming compounds present in all petrols.

Highly rated
The fuel has an octane rating Research Octane Number (RON) of 99 (typical 99.4) and minimum Motor Octane Number (MON) of 87 (typical 88). Comparatively, standard unleaded petrol is rated at 95 RON and 85 MON and ordinary super unleaded at 97 RON and 86 MON.

Fewer deposits
Tesco 99 Octane also contains low levels of olefinic compounds, typically less than 5%, compared with up to 18% in standard petrols. These compounds can lead to the creation of engine deposits. To ensure Tesco 99 Octane remains ‘cleaner’ petrol, an additive package is included with twice the protective power of typical 95 octane fuel. It removes existing deposits and helps the engine to run more smoothly.

We also typically include 5% bioethanol – a clean and pure ultra high-octane component which is also renewable to help cut greenhouse gas emissions.
