Abstract

A gun oil composition consisting essentially of:

• • 2.0 to 15% by weight of isopropanol;
  • 20 to 60% by weight of heptane or a petroleum distillate;
  • 3 to 20% by weight of a mixture of viscosity modifiers, antioxidants and reducing agents including benzyl acetate, t-dibutyl-p-cresol, at least one alkyl succinic acid, at least one zinc alkyl thiophosphate, polymethacrylate, and methyl silicone polymer, wherein the alkyl is C₁ to C₆ alkyl; and
  • the balance, lube oil bright stock to 100% by weight.
