An apparatus for improving vehicle efficiency mainly includes a vehicle engine and an oxygen producing device. The oxygen producing device is located on an intake passage between an air filter and an intake manifold to increase oxygen content in the air. When the air enters the air intake passage and passes through the air filter, the air and pure oxygen are drawn into the engine through the intake manifold. Hence combustion in the engine is proceeded more efficiently due to increase of oxygen content. And the engine has a higher transformation effect to boost horsepower. Fuel-saving effect of the engine also improves. And exhaust gas can be discharged more eco-friendly to reduce air pollution.
