The invention relates to the field of oil-refining and can be applied for the lubrication of friction units and reliable corrosion protection of surfaces of mechanisms from ferrous and nonferrous metals. The protective lubricant is made on the basis of petroleum oil and thickener – AI-soap. In the second variant as petroleum oil it contains less viscous basic oil with У100, no less than 17 mm2/sec, and as a thickener - AI-soap of unsaturated stearinic acid or mixture of unsaturated acids C12-22. The oil additionally contains acid ether of alkenyl succinic acid and polymer viscous additive polyisobutylene or vinipole with molecular mass (m.m.) 4000-25000 at such proportion of components, mass,:
