What happens when you drive a long distance and come back from a hot car, check that the oil is half

According to your description, the oil is reduced a lot, you can observe whether there is an oil leak from the bottom of the engine (there will be a lot of oil on the surface of the oil pan), and if so, it means that there is a leak in the body. If not, start the engine and slam the throttle to check for blue smoke coming out of the exhaust pipe. The cause can be found by examining these two aspects.

It must be an oil leak, you can re-ignite to see if the oil fault lamp is on, if it is on, you must go to the 4S shop in time to test and repair. If the oil lamp is not lit, you must also go to the 4S shop to check the oil.

Hello! The car should check the oil, after the hot car is turned off, wait for 5 minutes and then check, after pulling out the oil dipstick, the oil should be in the middle of the oil dipstick scale. After running a long distance, check the number of kilometers driven, whether the car will burn oil, check whether the engine will leak oil, and check it in many ways.

It is inevitable that the oil that plays a lubricating role between the piston and the cylinder wall in the engine will participate in the combustion, as long as it does not exceed one liter within 5,000 kilometers, it is normal oil consumption, and vice versa.

Burning engine oil is basically caused by piston ring stagnation. As long as there is no serious strain on the cylinder wall, it does not need to be overhauled. Changing the maintenance of high-viscosity engine oil is only an expedient measure to treat the symptoms rather than the root cause, and it will do more harm than good.

The solution to burning the oil.

In the habitual thinking of car enthusiasts, they always think that burning engine oil should be overhauled, so that they not only have to bear high maintenance costs, but also bear the unpredictable risks and depreciation losses brought about by the overhaul. Destroy the airtightness and precision of the engine. And there is a possibility that the engine oil will burn again after tens of thousands of kilometers, so overhauling the engine is not sustainable.

Now the no-dismantling technology has been very mature and gradually accepted by the majority of car owners. In particular, the non-destructive repair products containing PNF patented technology have completely gotten rid of the technical shackles of burning engine oil and having to go to the auto repair shop for overhaul, without removing a screw, repairing and releasing the piston ring stuck engine oil while driving, with remarkable results.

The dangers of too little oil:

1. Less oil will lead to pulling the cylinder.

2. Too little oil will cause poor lubrication and wear of parts, and too much will cause increased running resistance.

Engine oil is known as the "blood" of the car. It can play the role of lubrication and wear reduction, auxiliary cooling and cooling, sealing leakage, rust and corrosion prevention, shock absorption and cushioning for the engine.

Do you mean that after driving for a while, it is less than half, or if you just changed the engine oil and found that it is less than half. In the former case, if it occurs at the next maintenance mileage, it is not more than worrying too much, which is a normal wear and tear. The second situation is that the oil is not enough, and half of the oil scale is half a liter of oil less.

There are several possibilities:

1. There is leakage of engine oil, which can be done by checking the appearance of the engine to see if there is oil leakage.

2. It may be that the piston ring is on the right side, or there is a break (especially the oil ring), which leads to poor cylinder sealing, so that the oil enters the cylinder and burns off.

3. Or the piston ring (especially the oil ring) is seriously worn, or the piston and the cylinder liner are seriously worn, resulting in poor cylinder sealing, so that the oil enters the cylinder and burns off.

4. The cylinder gasket is damaged, causing the oil to enter the cylinder and burn off.

5. The oil cooler is broken, so that the oil enters the cooling water, this can be checked whether there is oil in the water tank.

The phenomenon of burning engine oil can occur only when the general vehicle travels 15 200,000 kilometers normally. It is normal for a vehicle to consume 1 liter of engine oil every 5,000 kilometers, and if it exceeds this standard, the Yacco brand oil master tells the owner that there are three phenomena to determine whether the car is consuming normally or burning oil.

1. When the vehicle starts, the exhaust pipe will emit blue smoke, but the blue smoke will disappear after a while, but this phenomenon will still occur on the second and third days, indicating that the vehicle has the phenomenon of burning engine oil.

2. When the vehicle is driving or starting in situ, a large amount of blue smoke is emitted by pressing on the accelerator exhaust pipe, and there is basically no at idle, indicating that the phenomenon of burning engine oil is serious and should be repaired as soon as possible.

3. In addition to the exhaust port, if the oil injection port also emits blue smoke, it means that it has reached the late stage, if you do not seek medical treatment, wait until the oil pressure is too low and cause the engine to alarm, the loss of the engine will be very large.
