How to accurately judge the increase in engine oil? How to properly check the oil level of your engi

If it's an old driver, it's very easy to judge! Whether the oil is increasing or not, the oil dipstick scale can be detected at a fixed time. If it increases and you can smell the smell of gasoline, it means that it has been mixed with gasoline; If there is white foam in the engine oil, and the coolant becomes less at the same time, and water droplets appear on the oil cap, it may be that the coolant is mixed in the engine oil, and the engine oil should be replaced in time.

Novice drivers, I personally recommend going to the 4S shop to do a check, after all, I can't be sure. More oil isn't a big deal now. Moreover, this phenomenon is not common in the south, and is mainly seen in the northern alpine regions.

The car is upgraded in the ECU, or the fuel injection timing is corrected (the fuel injection timing is corrected to speed up the heating up of the engine after starting, suppress the rise of the oil level, and promote the rapid volatilization of the mixed fuel and re-combustion.

In this way, the problem of oil increase is basically solved. Of course, you should also take measures to prevent the phenomenon of oil increase.

When winter comes, change the antifreeze, change the oil if possible, and warm up the car before driving, which can basically prevent the increase in engine oil.

It's a hassle to drive in winter, and you have to be careful with your turbo car anyway, so it's best to take precautions.

Hello, at present, the car is equipped with the design of the oil ruler, and the oil level can be checked by pulling out the oil ruler in the normal cold car state, and some models use electronic induction to display in the center console.

Don't be afraid of wasting money, change the oil if you can, anyway, if you want to do it, you can do a full set, and there is no harm in changing it.

How to check car oil.

1. Time to check the oil.

Be sure to check when the car is cold (e.g., not running overnight) because the oil will splash when the car is hot, and the dipstick will be inaccurate. The correct time is: after the engine is turned off, let it stand for 15 minutes and then check the oil dipstick, if you need to check it often, you can check it before starting the vehicle in the morning, and the oil level height at this time is also accurate.

2. Check the location of the engine oil.

When checking the dipstick, make sure that all four wheels of the car are parked at the same horizontal height, which means that there should be no tilt in the front, back, left and right. As soon as the body is tilted, the oil level in the oil pan changes and the measurement results are inaccurate. There is a relatively simple way to judge is to park the car, neutral gear does not pull the handbrake, if the car can stop still, it is basically horizontal, of course, the situation of left and right tilting is best to avoid.

Generally, check the oil quantity of the engine, directly pull out the oil dipstick, and then see if the oil quantity is in the middle of the upper and lower scale marks.

<> "How to tell if engine oil is good.

Engine oil is known as the "blood of the engine", and its importance to the engine is self-evident. Everyone knows that the main function of engine oil is lubrication, in addition to cooling, cleaning, rust prevention, corrosion prevention and other functions. The quality of the engine oil will have a direct impact on the service life of the engine.

So how to identify and judge the quality of engine oil?

The easiest and most effective way to identify the quality of the engine oil is to open the oil cap at a glance. Under normal circumstances, if you have been using good engine oil, even if you have traveled more than 100,000 kilometers or even 200,000 kilometers, the oil cap and oil filling port are bright and shiny, and the oil is shiny. On the other hand, if the oil is not used properly, the oil cap and filler port will mostly be black, slimy, and sludge all over the place.

To sum up, there are about three states of the oil filler:

1.The oil filler port is covered with sludge.

This is mostly due to the long-term use of low-quality engine oil, or the engine has a serious oil burn.

The oil cap and filler port are covered with slimy sludge.

2.White emulsion appears at the oil filler.

This situation is mostly due to the coolant entering the lubrication system, causing the oil to be emulsified by the coolant at high temperatures.

The oil filler port is stuffed with emulsion.

3.The oil filler port is oily and shiny.

This is the most ideal state, shining gold, opening the valve chamber, it must also be "splendid", pleasing to the eye.

Many novices don't know how to check the engine oil, the amount of engine oil directly affects the working performance of the engine, so how to see the amount of engine oil in the daily driving process?

The way to check the oil is to park the vehicle on a flat road for 2 to 3 minutes when it reaches normal operating temperature, pull out the oil dipstick, and check that the check is incorrect when the car is cold in the morning.

If there is an increase in oil, open the lid first, pull out the dipstick to see where the oil is, and after a while, pull out the dipstick to see if the oil level has changed. It needs to be checked in the cold state of the chain, because when the car is hot, the oil will splash and the dipstick will not be accurate. The correct way to do this is to let the engine stand for 15 minutes after the engine is turned off, and then check the dipstick.

Oil increases generally occur in direct-injection engines and also often occur in winter. Fuel from a direct-injection engine is injected directly into the direct-injection cylinders. Unlike manifold injection, which has more time to mix with the air body, more or less fuel will be injected into the cylinder wall causing wet walls.

Under normal circumstances, due to the high temperature of the engine and the crankcase forced ventilation system, this small amount of gasoline will enter the combustion chamber through the crankcase forced ventilation system and burn again, without causing fuel dilution.

In fact, a slight increase in engine oil does not make the call too harmful, and it does not affect driving, but if the oil increase is too severe, the viscosity and performance of the engine oil will decrease. As a result, the engine is poorly lubricated, leading to accelerated wear of the friction parts inside the engine. In addition, due to the reduced viscosity of the diluted oil, it also increases the possibility of the oil escaping into the combustion chamber, and too much oil enters the combustion chamber for combustion, which is easy to form carbon deposits at the pistons, valves, and fuel injectors, thus affecting the performance of the engine.

If there is an increase in engine oil, you must go to the 4S shop for maintenance as soon as possible to avoid greater losses.
