Abstract:
Balanced oil additive compositions can be used in the engine, gears and elsewhere of mobile equipment. Appropriate concentrations of basic detergents, dispersants, antioxidants, extreme pressure agents and friction modifiers are balanced.

1,162,443. Additives for oils and greases. MOBIL OIL CORP. 24 Oct., 1967 [10 Nov., 1966], No. 48318/67. Heading C5F. A lubricant comprises 0À02 to 35 weight per cent of a mixture of 5 to 60% of an alkyl or alkenyl phosphite and 95 to 40% of a compound selected from sulphurized polyisobutylene, sulphurized triisobutylene, and sulphurized dipentene. Suitable phosphites are dibutyl-, ethyl hexyl-, oleyl acid-, tributyl-, tris-2-chloroethyl-, mono- and di-oleyl-, and mono- and didodecyl-, phosphites. The base lubricants are oils having viscosities of 40-6000 S.S.U. at 100‹ F., viscosity indexes of 0 to 100, and average molecular weights of 250-800, e.g. mineral oils of S.A.E. grade 5-140, aliphatic phosphates, esters and diesters, silicates, siloxanes, polyoxalkyl ethers, and polyesters and greases made from any of the above oils or from oils such as polypropylene, polypropylene glycol, trimethylol propane esters, neopentyl and pentaerythritol esters, di-(ethyl hexyl) sebacate, di- (2-ethyl hexyl) adipate, dibutyl phthalate, fluorocarbons, silicate esters, silanes, esters of phosphorus-containing acids, liquid ureas, ferrocene derivatives, hydrogenated mineral oils, chain-type polyphenyls, siloxanes and silicones, alkyl-substituted diphenyl ethers and phenoxy phenyl ethers, and thickened with metal salts or soaps, surface modified clays and silicas, aryl ureas and calcium complexes. Antioxidants, antifoamants, detergents, antirusts and dispersants may also be included in the oils and greases.
