ABSTRACT:
This invention relates to a fuel composition comprising a base fuel having a final boiling point above 150° 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.
