Reduce exhaust emissions, HC can be reduced by about 50%, improving the atmospheric environment; 4. Save fuel, with an average fuel saving of 2%; 5. Easier cold starts for cars, quick acceleration, and stable idle running with strong performance; 6. Have anti-rust and demulsification properties, preventing corrosion of engine components; 7.
