Why does the car speed up so quickly after changing the oil?

After changing the engine oil, why does it obviously feel that the car is speeding up very quickly?

First of all, if the oil is not changed for a long time, it will lead to insufficient power and even engine damage in the car. During engine operation, there is a relative sliding between the piston and the cylinder, and if the oil lubrication force is insufficient, it will lead to serious wear of parts.

In addition, if the oil cooling effect is reduced, the engine cannot be cooled in time, and the long-term temperature is too high will lead to shortened life and even affect the overall performance of the car.

After all, the engine is the power of the car and occupies the position of the "heart" of the car, so it is very important to change the oil in time for engine maintenance.

Secondly, the engine oil can wash some impurities on the engine parts, such as the carbide produced, oil sludge and other substances, which plays a cleaning role in the engine.

In addition, the oil creates a seal between the pistons, preventing outside contaminants from entering the engine.

Therefore, if the oil is not changed for a long time, there will be more and more impurities and pollutants, which will not only not be able to clean the engine during the cycle, but also may cause failure due to some impurities blocking the engine.

Because the oil has been changed, it may be that the quality of the oil is very good, plus it is a new oil, the temperature is also suitable, and the viscosity of the oil is just right, so that the car will speed up very quickly.

It may be that the previous oil and the vehicle did not have enough pace, or it may be that the vehicle is more adaptable and has more power after changing the gasoline.

Dear, hello, the reason for the low idle speed of the car after changing the engine oil is: changing the oil to improve the internal lubrication degree of the engine, the wear of the internal parts of the engine is reduced accordingly, and the idle speed is naturally reduced. The amount of oil replaced by the car should be slightly lower than the scale on the oil dipstick, too much oil will increase the rotational resistance of the crankshaft, reduce the output power of the engine, and the excess oil will enter the combustion chamber to participate in combustion, causing the vehicle to burn oil, blue smoke, and increase fuel consumption.

When adding lubricating oil, be sure to keep it slightly lower than the scale on the dipstick. In addition, it is necessary to grasp the type of engine oil, the season, the climate, the engine displacement, the technical performance and many other factors. The car owner buys the best engine oil, and it is best to go to the store, Nianhuai Zheng special oil change center and Ming lead authorized dealership.

As for distinguishing whether these retailers are authorized by the manufacturer,

1.The oil is too thick: because when the oil is too thick, the engine needs to have a high idle speed called fast idling, and at this time, the amount of fuel injection is increasing because of excessive resistance. Moreover, when the fast idle speed is controlled, its idle learning value needs to be corrected.

2.Excessive carbon deposits: High rotational speed is generally the reason for the storage of too many silver segments in carbon deposits. Timely cleaning of the throttle and idle motor can usually solve the problem. Reputation.

3.If the engine oil is too full or the hand shakes to add excess oil and does not deal with it, it may face the situation of burning oil, especially when the number of revolutions is very high, it will increase the working load of the engine, and the engine will turn faster.

After the oil maintenance, I feel like my car is speeding up, and there are four main reasons for this. First of all, there is the role of the mind. I know some people wouldn't agree with that, but it's true.

Just like going to a car wash, after washing the car, the mood will become very happy for the renter, and many car lovers have similar feelings. Because after washing the car, we feel like we have washed ourselves, and our hearts become comfortable. And after the car wash, the power of my car is also more prominent, and I feel that the horsepower has soared directly.

Secondly, it is the maintenance and replacement of the engine oil. Changing the engine oil can improve the lubrication performance of the engine oil, because the oil continues to add impurities during use, the wear resistance is reduced, the lubrication effect is reduced, and the internal resistance is increased. Changing to a new engine oil after maintenance can improve performance.

Thirdly, there is the change in the viscosity of the oil. Oil viscosity may vary before and after service, with the previous oil being more viscous and the new oil being replaced being less viscous. Engine oil with low viscosity has low resistance and good power.

Different brands of engine oils have different viscosities, so even for the same model, different brands of engine oils may vary. Fourth, after the end of maintenance, there are fewer impurities in the oil. Please do not underestimate the impurities in the engine oil, as they will not only affect the lubricating performance of the engine oil, but also affect the heat dissipation performance, fluidity, etc. of the engine oil.

Therefore, after replacing the new engine oil, the fluidity of the oil in the engine becomes better, the heat dissipation performance is improved, and the efficiency of the engine will of course be improved. To sum up, my car will naturally become faster when it becomes faster.

First of all, if the oil change removes your own rotten factor, and the actual mess improvement is obvious, then I can only say that your car is not in good condition after driving for a while! That's not a good thing! Take, for example, the most commonly used turbocharger oil.

Turbocharging conditions are complex and temperatures are high. Typically, a viscosity of 40 is required. Let's say you add 30.

It may be a little easier to start at a low temperature, but it's not a good idea!

Engine oil is equivalent to the blood of the car, bringing endless power to the car and braking. Engine oil is indispensable for machine lubrication, especially for the engine. Too much or too little is not good, generally the highest liquid level is a little lower, and it is necessary to check regularly.

Before the inspection, the vehicle should be parked on the horizontal plane, and the engine should be started to idle for 5 mis "minutes";

Stop the engine, wait for 3 mis, pull out the oil dipstick and wipe it clean, reinsert the dipstick and take it out again, and record the oil level on the dipstick;

The correct oil level should be between the highest and lowest positions;

Use your hands to beat the oil on the dipstick, check the viscosity of the line, and see if there is any gasoline smell and bubbles;

If the oil level is too high, even if the reason is inquired, it should be ruled out, and the cause may be caused by cooling water or gasoline entering the crankcase.

Five misunderstandings about the use of automobile engine oil:

Myth 1: Engine oil is often added but not changed.

For some German oil-burning car owners, it is not wrong to check the engine oil frequently, but only replenishing and not replacing can only make up for the lack of oil quantity, but cannot fully compensate for the loss of lubricating oil performance. During the use of engine oil, the performance will gradually decrease due to pollution, oxidation and other reasons, and there will also be some consumption, so that the quantity will be reduced.

Myth 2: The role of engine oil additives is large.

A good quality oil is a finished product with a variety of engine protection functions, and the formula already contains a variety of additives, including anti-wear agents, and the oil is most important to balance the formula to ensure that the performance is fully realized. Since then, the addition of other additives not only does not bring additional protection to the vehicle, but is easy to react with the chemicals in the oil, resulting in the decline of the comprehensive performance of the oil.
