Semi-synthetic two-stroke engine oil formulation

摘要

A semi-synthetic two-stroke engine oil formulation which comprises a base oil consisting of a high-viscosity mineral oil, a medium-viscosity mineral oil, a solvent and a mixture of three polyisobutylenes with different molecular weights, and appropriate detergents and dispersants. This semi-synthetic two-stroke engine has both high lubricity and high detergency, and also meets the requirements of low smoke and low exhaust system blocking.
