A refractory formulation containing an anhydrous solvent, an oleophilic rheology modifier and a refractory aggregate exhibits non-thermoplastic behavior, and remains plastic and formable at temperatures in the range of 10 degrees Celsius to 180 degrees Celsius. The oleophilic rheology modifier may effectively bind with the solvent to create a gel-like structure with organic solvents with moderate to high polarity. A phyllosilicate clay that has been treated with a quaternary fatty acid amine may be used as the oleophilic rheology modifier.

An oleaginous corrosion-resistant lubricating composition comprising at least one poly-alpha olefin synthetic oil and effective amounts of metal salts of sulfonic acids metal salts of carboxylic acids, metal salts of mixtures or combinations of sulfonic and carboxylic acids, alkylated aromatic compounds as solubility modifiers, pour-point depressants, at least one antioxidant, and metal deactivator compounds.

A lubricating oil composition comprising (A) a lubricating oil base oil the kinematic viscosity of which at 100 C. is in the range of from 1.4 to 6 mm.sup.2/s, (B) from 250 to 2000 ppm in terms of molybdenum of a molybdenum dialkyldithiocarbamate, (C) from 20 to 500 ppm in terms of sulphur of tetrabenzyl thiuram disulphide and (D) from 0.05 to 3.0 mass % of an amine. The lubricating oil composition of the present invention has a superior friction reducing effect and which has a superior fuel economy effect.
