Oil consumption, imported new enginecylinderandpistonThe processing precision of,engine oilThe consumption can reach 0.1-0.2g/kwh, and the oil consumption of German cars is higher than that of Japanese cars.The original design value of oil consumption of domestic vehicles was 0.5-2.0g/kwh, but now the oil consumption level is gradually approaching the foreign level.
The power of cars with 1.6L-2.0L displacement is between 90-120kw, the average driving speed is mostly 60-80km/h, and the engine oil is changed every 5000km.We can calculate the oil consumption of a car with a power of 100kw, an average driving speed of 70km/h, and an oil consumption of 0.2g/kwh. The oil consumption of 5000km is 5000km/70km/h * 100kw * 0.2g/kwh=1429g, and the proportion of oil is about 0.881429g oil, which is about 1.624L oil.

For ordinary cars, it is normal to consume 1.5L of engine oil every 5000km.In addition, low viscosity oil is also easier to wear than high viscosity oil.For some vehicles in poor condition, due to the large gap between the piston ring and the cylinder wall, some vehicles even have a slight oil burning phenomenon. At this time, 20W/50 viscosity oil with high viscosity should be used. If 10W/40 or 15W/40 viscosity oil is used, the oil consumption will be large, especially for diesel vehicles.
Some oil has a strong cleaning function. When other lubricants are used in old cars, the glue and carbon deposits on the piston and piston ring are dissolved by nano ceramic oil, so the gap between the piston and the cylinder block will increase, and the sealing condition is poor. At this time, as long as the piston ring is replaced, the oil will not burn, and the power will also increase, otherwise,Oil consumption will also increase.
