How long can you run without oil? The car is short of oil, can I still drive?

Can't run. The lack of engine oil will make the engine not get enough lubrication when working, and it is easy to produce sound such as valve knocking and cylinder knocking. It is best not to continue driving without oil, you can find a nearby repair shop or gas station to add the corresponding oil, remember not to mix other oil, otherwise the performance of the oil will change, such as lubrication performance, cooling and heat dissipation capacity decreased, etc., can not better protect the engine.

The role of motor oil.

1. Lubrication. The oil forms a continuous film of oil between all the friction surfaces of the moving parts to reduce the friction between the parts.

2. Cooling. The oil flows through the working surface of the part during circulation, which can reduce the temperature of the part.

3. Cleaning. The oil carries away metal debris from friction surfaces and flushes away carbon deposits deposited on cylinders, pistons, piston rings and other parts.

4. Sealing. The oil film attached to the cylinder wall, piston and piston ring can play a role in sealing and leaking.

5. Anti-rust. Engine oil has the effect of preventing rust on parts.

This depends on how much is missing, the current engine in the case of no organic oil, running more than ten kilometers is no problem, but it is not recommended to try, although many engine oil brands promote no oil when how many kilometers, but it is not recommended to try, generally as long as the alarm light is not on, you can continue to run, after the light is on, do not be too nervous, pull over, check the leakage, if not leaking, just lack a little, you drive to the nearest repair shop has no problem.

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. The lack of engine oil will cause the engine to heat up badly, the car will shake abnormally, the water temperature will be high, the valve will sound, and in serious cases, it will even strain the cylinder wall or burst the cylinder.

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 car is short of oil, after the oil alarm, it is best to find a place to park immediately, do not run, it is best to immediately shift the gear to neutral, in the case of ensuring safety, first turn off the engine, and then slide, use the vacuum established by the engine, only use one foot brake to stop the car slowly, and finally check the oil dipstick. Contact a maintenance person.

When the car runs out of oil, it is advisable not to continue driving. If you continue to drive, it will cause some damage to the engine, and if it goes on for a long time, it will be more serious and the cost of repair will be more expensive. If there is a lack of oil in the engine, it will affect the lubrication and heat dissipation of the engine, and if it continues to drive, it may cause the engine to pull the cylinder.

The car has no oil, which means that when the engine is working, there is no way to protect the engine, lubricate the engine, cool and dissipate heat, clean carbon deposits, anti-corrosion, anti-wear, etc. If you continue to drive without oil, the frictional resistance of the friction surface of the engine parts increases, which increases the degree of wear.

The gap between parts is also increasing. At the same time, the engine cannot be cooled and dissipated in time, and there will be ablation, cylinder pulling and other phenomena, which will accelerate the aging of engine parts and shorten the service life of the engine over time.

Therefore, do not drive with insufficient or no oil, as this will only increase the burden on the engine, damage the engine even more, and if the situation is severe, it will require high repair costs.

The car is short of oil.

At the same time, it is also important to remember that the oil volume should not be too large, that is, the oil level should not exceed the upper limit of the oil dipstick, otherwise it is easy to cause the engine load to increase and affect the power;

Over time, the engine exhaust ventilation system is also easily damaged, carbon deposition increases, and excessive oil volume will also cause the phenomenon of burning engine oil. The engine is the "heart" of the car, and the oil is the "blood" of the car, which is indispensable.

If the car lacks oil, it can't continue to drive, and you need to add oil to continue driving. Continuing to drive without oil is likely to cause the piston to smash the cylinder block and the car may stall.

The main role of engine oil is lubrication, sealing, heat dissipation, rust prevention and other four major effects, in the case of lack of oil, the engine in the case of insufficient lubrication, poor sealing, insufficient heat dissipation, will be excessively worn, and even local serious wear or damage, serious will lead to engine scrap.

If the oil lamp is turned on and the engine sound becomes louder (the engine will sound when there is no oil lubrication), it is recommended not to turn it on, if the engine sound does not become louder as before, it can be turned on slowly in an emergency.

Under normal circumstances, the car is driven to the next time the oil is changed, the oil loss is very small, and there are two possibilities for the lack of oil when the car drives more than 2,000 kilometers

1. Check whether there is any leakage under the car engine;

Second, take the car to observe whether the rear exhaust is blue, and smell whether there is a smell of burning engine oil.

If there is oil burning, either the exhaust gas check valve is broken, and oil enters the throttle; Either the piston sealing is not good and needs to be overhauled.

There are two reasons for the lack of engine oil, one is leakage, the other is to burn the oil, so you have to see what is the reason for your lack of oil, if it is leakage, it is to be repaired in depth, if it is to burn the oil, see where it is burned, it is from the West Gate Post when it is alive, so it can decide how to repair it, and then it depends on the severity of the burning, if it is slightly within the 5000 km maintenance cycle, if it exceeds the liter, in this case it is best to repair, Otherwise, it is more troublesome to rest at that time, alas, it is better to explain the reason clearly in the maintenance and inspection.

I'm really not sure if my bid pool is going to be reached, and it's offline. Then you hurry up and add engine oil, if there is a shortage of engine oil at 2000km, then there is a problem, there must be something wrong here, uh. So hurry up and find uh harvest on the feeling of personal time to check.

Check the chassis, oil drain screws, oil filter or engine seal for oil leakage, if not, it is burning oil.

1.It is recommended to operate and maintain according to the maintenance manual. Regularly maintain the owner, and change the engine oil once every 5,000 kilometers. Some vehicles will have a hint.

2.The choice of oil should be based on the requirements of the engine, and it is not necessary to use an overly high-grade oil on a less demanding engine, nor should a lower grade oil be used on a more demanding engine.

3.Multi-grade oil should be selected as much as possible, because multi-grade oil has a better protective effect on the engine due to its saving, long life and high efficiency. Based on the characteristics of multi-grade oil, premature blackening and oil pressure may be smaller than that of ordinary oil during use, which is normal.

4.The quality of some domestic brand-name engine oil is quite good, and it is much lower than that of imported similar products, so it can be used with confidence.

If there is a shortage of engine oil for 2000 kilometers, either the oil is leaking, or the car has the phenomenon of burning engine oil, which can be checked by the repair shop.

If there is no trace of oil leakage from the outside, then first observe whether the vehicle emits blue smoke, and then you need to check the engine oil burning.

Hope mine can help you.

If the possibility of leakage is ruled out, it is the machine burning oil, and it is recommended to check the engine.

If it doesn't leak, it will burn the engine oil.

If the car is short of engine oil, you can buy a bottle of engine oil in the trunk, and pour it directly into it if you burn the engine oil.

Burning engine oil is a common problem of Volkswagen's cars, in this case, you should have a pot of engine oil in the trunk, and add it in time when there is a shortage of engine oil.

"Volkswagen runs long distances and lacks engine oil, there are the following reasons: The engine oil itself has a certain consumption, and this consumption is normal. If you consume too much, there is a problem of burning engine oil. Burning engine oil is caused by the following factors, as long as the following problems are solved, burning engine oil can be solved.

It is not difficult to always have a tank of engine oil in the trunk, just be careful not to smoke in the car.

Lack of engine oil, how much is missing?

If there is less than too much on the ruler, it should be fine to drive back slowly.

Burn the engine oil, and the engine oil is prepared on the car, so check it at any time.

Will the car master definitely check whether his car is short of oil in advance? The car must also be oiled, and if there is a shortage of oil, he will definitely add it at any time.

If the car lacks oil, it is not recommended to run long distances, because in the process of running long distances, the engine has been running at high speed, and the lack of engine oil may lead to the movement of the engine pistons, the lubrication is not very sufficient, which will lead to high engine temperature, damage to the engine, and cause irreversible damage.

Thank you, if the maintenance time or kilometers are up, you need to change the oil and filter. It is best to follow the time and kilometer requirements on the maintenance manual. If there is no maintenance time and kilometers, in the case of no start, pull the dipstick, the oil level is lower than or close to the scale line under the dipstick, you need to add some oil in an appropriate amount, and keep it between the lowest scale and the highest scale of the dipstick oil level.

However, when it comes to maintenance time and kilometers, it is still necessary to replace the oil filter, and the waste oil generally contains a certain amount of tiny metal dust and organic acids, which will damage the engine. Failure to maintain it on time will accelerate engine wear, increase fuel consumption more than it costs, and shorten the life of the engine. Pay special attention to one point:

Do not mix different types of oil, as the general maintenance manual will have requirements for oil viscosity. It is best to add the same type of engine oil from the factory, and mixing the engine oil will change the viscosity of the oil, affect the heat dissipation and lubrication effect of the engine, and will also increase fuel consumption and reduce the service life.

There is no chance that the engine will cause mechanical damage to the engine.

The chain-driven engine uses guide rails to guide the toothed chain. The guide rail is tensioned by a hydraulic cylinder driven by press oil, and the pressure is proportional to the speed of the engine.

When the oil is excessively consumed, it is not replenished in time, and on the way at high speed, due to insufficient oil pressure and insufficient tension, the toothed chain will run, and the timing will be incorrect, and the light one will have insufficient power and high fuel consumption; Heavy cases can cause the piston to hit the door, causing mechanical damage to the associated connectors.

Solution: Before the vehicle goes out for a long distance, be sure to check the oil level by yourself. Generally, it is sufficient to keep it in the midline of the oil scale restriction area.

Be sure to park the vehicle on a relatively level road surface for inspection, and the vehicle is as free of load as possible. The engine oil should not be added to the upper limit of the engine oil, otherwise it will cause the resistance of the crank and increase the friction loss; On the other hand, it will cause the crankcase pressure to rise, the oil consumption will increase, and the engine will be destroyed.

After all, the expressway is different from the ordinary highway, and the interval between the two exits may be tens of kilometers, in this case, there are 3 options, one is to ignore the EPU alarm and continue to move forward; the second is to stop in the emergency lane and wait for rescue; The third is to buy engine oil immediately to replenish it. We know that the first option is certainly the most undesirable, the engine in the absence of oil in the case of long distances, will undoubtedly affect the service life of the engine, the heavy will cause fatal injuries to the engine-related parts, the light may affect the performance of the engine, such as poor power, louder noise, etc.

If it is the second option, wait for rescue, first, the vehicle is not very safe to park in the emergency lane; The second is that I feel a bit of a fuss, after all, the lack of engine oil does not mean that it is anchored. So the third option is the best choice, the trunk is best to bring its own oil, no oil is best to go to the service area to buy, there are many service areas on the highway, generally in the service area gas station can buy oil. But now there is another problem, it is definitely difficult to buy engine oil of the same brand and sequence in the service area, so what should I do?

This brings us to the question of whether different brands of engine oil can be blended. We know that the main body of engine oil has two parts: base oil and additives, base oil is the main body, and additives are for excellence, for better oil quality and performance. On the basis of this, it seems that different brands can be mixed, but from the perspective of additives, different brands, even products of the same brand and different sequences, are not recommended.
