Abstract

PURPOSE: To obtain a lubricating oil suitable for 2-cycle engine operated under severe conditions at low fuel consumption by adding an antioxidant, a dispersant, a cleaner, and a defoamer to a base oil composed of a synthetic oil and a mineral engine oil.
CONSTITUTION: To 100wt parts by the base oil (A) prepared by adding 20W50wt parts of a mineral engine oil (b) to 100wt parts of synthetic oil (a) such as pentaerythritol ester and alpha-olefin oligomer, 2W10wt parts of an antioxidant (B) such as phenothiazine and zinc thiophosphate, 3W6wt parts of a dispersant (C) such as succinimide and benzylamine, 4W9wt parts of a cleaner (D) such as calcium sulfonate, 1/200,000wt parts of a defoamer (E) such as dimethylsilicone, 2W5wt parts of an extreme-pressure additive (F) such as tricresyl phosphate and dibenzyl disulfide as needed, and 0.05W0.2wt parts of a metal inactivator (G) such as benzotriazole and indazole are added.
