Honda Hao Ying bought a car that runs 9000 kilometers a year. It usually has seven kinds of oils. How can I display 20 oils after maintenance?

(1) The viscosity of the replaced engine oil is too high, resulting in a relative increase in engine load and fuel consumption;

(2) The quality of the replaced engine oil is not good, which leads to poor lubrication of the relative moving parts of the engine, increased friction and relatively high fuel consumption, which is more serious for turbocharged engines.

Different oil quality, the corresponding displacement is also different, and the corresponding model is also different. Generally, it is good to replace the engine without supercharger with a semi-synthetic engine. Don't add too good engine oil to cars with small displacement. Synthetic engine oil is generally high in viscosity, which is suitable for large-displacement vehicles with supercharger. The more expensive the oil, the better for your car. It's really appropriate. You should add oil that is not suitable for your car. In addition, it depends on whether you have washed the accelerator. If you have washed it, you should reset it. If it is not reset, the throttle opening will change, which will also affect fuel consumption. At the same time, whether the amount of engine oil is appropriate, too much or too little will have an impact.

The increase in fuel consumption after changing oil from Hao Ying may be related to the high viscosity of the oil you changed. The oil used by Honda Hao Ying should be 0w-20 or 5w-30. If the oil you change is higher than this viscosity, it may lead to an increase in fuel consumption.
