Twelve studies reviewed by specialists concentrate so much in tribológicas the chemical aspects and of the tests of automotion lubricants and the additive development. With the purpose of to help the industry of the automobile to fulfill lower standards of emission, higher fuel objectives, and longer intervals of drainage associated with a reduction to the minimum of adverse the environmental effects, the industries of petroleum and the additive suppliers are developing to low SAPS (sulphated ash-gray, phosphorus and sulphur) and lubricants of high tribológico performance to face these challenges. These documents include: • Additive impact in the oil and the base of the characteristics of the oil of the motor • Low level of lubricant SAPS the development and tests • The connection between the additive chemistry and the emissions. • tribológico problems of yield like the retention of the fuel economy, protection against the wearing down, and the reduction of the friction • Motor train of the evolution • Industrialist methods of test for the oxidation of the lubricant • Several applicators engineering of surfaces, actually.
