What is the effect of adding too much oil?

Known as the engine “blood” oil is indispensable in the car, but not just add, you need to choose the right oil, but also have to choose the right amount of oil, oil plus more or less, will have a different impact on the car. So let's take a look, what are the hazards?

When you add less motor oil

Even in the years of poverty, can not lose the desire for happiness and good, those who get rid of the mediocre dream can always compile our simple life, for our simple time embellished hope. Can't say we always have to love life more, but always have a heart that knows how to appreciate and cherish.

Lack of motor oil will have an effect, how about adding too much motor oil? There will also be harm? 1. Increased fuel consumption, power decline in normal operation, the crankshaft rotation will be just enough to reach the oil level, so that when the rotation will appear to splash some oil droplets, if the splash to the connecting rods, pistons, and the cylinder wall, for lubrication of these parts, there is no lubricating oil channel, relying on the splash lubrication. If the oil is added too much, it will lead to too high a level, the crankshaft will have some parts immersed in the oil, when rotating will stir the oil, increasing the rotational resistance.

2. Increase carbon deposits, damage to auto parts crankshaft in the oil churning, there will be a large amount of oil will be churned to the piston and cylinder wall, and then into the combustion chamber combustion. If the oil contains a lot of impurities, it is not suitable for combustion, so there will be something that can not be burned off is the formation of carbon deposits. If carbon deposits are formed, it will have a long term effect on power and fuel consumption. The combustion of motor oil will generate toxic gases, which will make the three-way catalytic failure, affecting the performance of the car.

3. Crankshaft oil seal oil seepage, shorten the shelf life of the oil if the oil is a lot of churning, it will raise the pressure in the crankcase, the pressure acts on the crankshaft oil seal, will accelerate the aging of the oil seal or even deformation, ultimately leading to oil seepage. Accelerated oxidative deterioration of the oil will shorten its shelf life.

Therefore, oil plus more or less on the car to produce some harm, I remind you, you need to choose the car suitable oil and the right amount of oil, in order to take better care of their cars.
