## Abstract

Hydrocarbon fuels heavier than gasoline may be extended by addition thereto of immiscible alcohols in the presence of an acetal or ketal or orthoester co-solvent.

## Claims

### Claim 1

A novel hydrocarbon fuel composition heavier than gasoline comprising a hydrocarbon fuel heavier than gasoline; a water-miscible alcohol, ethanol or methanol which is substantially immiscible with said fuel; and as a cosolvent an orthoester.

### Claim 2

The method of extending a hydrocarbon fuel heavier than gasoline which comprises mixing (i) a hydrocarbon fuel heavier than gasoline, (ii) a water-miscible alcohol which is substantially immiscible with said fuel, and (iii) ethyl orthoformate thereby forming a single phase extended hydrocarbon fuel composition heavier than gasoline; and
recovering said single phase extended hydrocarbon fuel composition heavier than gasoline.
