ABSTRACT:
Endo-tetrahydroalkyldicyclopentadienes are mildly isomerized with AlCl.sub.3 whereby the changes in pour point and viscosities are such that the resulting isomeric mixture can be used as a diluent for a higher viscosity hydrocarbon missile fuel. The isomerication is such that essentially no alkyl-adamantanes are formed. The mole ratio of AlCl.sub.3 to the tetrahydrodienes is in the range from between about 0.001 to about 0.5. The temperature is in the range between from about 0.degree. C to about 100.degree. C.
