Does it cost oil when it's hot?

The engine will consume more oil in hot weather than at normal temperature. Adjusting fuel consumption with air: When driving in hot weather, the owner usually turns on the air switch to reduce the temperature, and the operation of the air switch needs to consume the power of the engine, so there will be some power loss, which will lead to an increase in fuel consumption. High temperature and low oxygen content lead to more fuel injection; According to the principle of thermal expansion and contraction, the higher the temperature, the smaller the gas density and the lower the oxygen content in the air per unit volume, so the engine has to inject more fuel to keep the engine running. The decrease of engine oil viscosity leads to the increase of engine oil consumption; At high temperature, the viscosity of engine oil will decrease, which will reduce the protective effect on the engine, thus increasing the wear of the engine and leading to an increase in fuel consumption.
