A fuel composition comprising gasoline having a sulphur content of less than 10 ppm by weight and an aromatic content of less than 25% by volume, characterized in that said composition comprises at least 5% by volume of olefins and is substantially free of any ethers. The fuel composition so formed has reduced emissions and improved fuel economy. The emissions from such compositions can be further reduced by incorporating therein a small amount of ethanol.

Fuel composition

This invention relates to a fuel composition comprising a base fuel having a final boiling point above 150&#xb0; C. and an anti-foam, characterised in that the anti-foam comprises di-isobutylene in an amount greater than 2.5% by volume based on the total fuel composition. The addition of this anti-foam reduces the break-up time for any foam formed significantly.
