Why did the Toyota Camry change the 10w40 engine oil and burn the engine oil

As long as you use engine oil that conforms to your engine number, it basically doesn't matter if you burn engine oil and engine oil from regular manufacturers.

The main reason for burning engine oil

There is a problem with the fittings, the wastegas valve, the valve seal, the cylinder is pulled in the cylinder, and the cylinder pressure is insufficient.

If the oil circuit is not cleaned for a long time, the antifreeze is not replaced in time, the oil life cycle is too long, the piston ring is stuck, and the more common situation is that the piston ring is stuck.

What is piston ring seizure

Stagnation starts from the oil circuit, the oil bears the temperature at 110 degrees, and the high temperature caused by the long-term unclean oil circuit makes the oil at a temperature of 120 degrees or higher for a long time, so that the oil will fail in advance, the small hole of the oil ring is very small, and the oil inside will be dried and scabbed for a long time, and a cylinder stuck is a liter of oil for 5000 kilometers, at this time, the working conditions of other cylinders will also begin to be bad, and soon the 4 cylinders are stuck, and it will become a liter of oil for 1000 kilometers or even hundreds of kilometers.

There are two ways to solve the problem of burning engine oil

Overhaul. PNF restoratives.

Benefits of this one:

In the case of overhaul, the cost is very high, the vehicle depreciates quickly, and the later run-in is also very troublesome. First of all, you need to find out the reason for your burning oil, oil circuit blockage, carbon deposits, piston ring stagnation can be repaired with PNF repair agent, there are many riders who have successfully repaired through PNF repair agent, you can refer to it.

；Burn the oil"；This is when the oil enters the combustion chamber of the engine and participates in the combustion along with the gas mixture. Vehicles appear"；Burn the oil"；The phenomenon will cause the vehicle oxygen sensor to be damaged too quickly, resulting in an increase in carbon deposition in the combustion chamber, unstable idling, weak acceleration, rising fuel consumption, excessive exhaust emissions and other adverse consequences.

Usually, if the maintenance operation is done properly, the phenomenon of burning engine oil occurs after 100,000 kilometers of operation.

The burning of engine oil is mainly caused by the wear of cylinders, pistons and piston rings.

Worn valves and ducts, and damaged oil seals can also cause oil burning.

The fault of burning the engine oil can be solved by repair.

The reasons why Camry burns engine oil and how to prevent it.

The engine oil itself has a certain amount of consumption, and excessive consumption is the problem of burning engine oil. There are many factors that affect the burning of engine oil, such as: fuel quality, driving conditions, driving habits, maintenance habits, etc., the following reasons will aggravate the oil consumption and cause the burning of engine oil, so that the vehicle appears:

1. Carbon deposition occurs in the combustion chamber, which makes the gas ring of the piston ring stuck, and the sealing is poor.

2. Oil sludge is generated in the lubrication system, and the oil sludge blocks the oil return hole of the oil ring and weakens the oil scraping performance.

3. Wear occurs between the piston and the cylinder wall.

4. The valve seal is corroded and aging, and the sealing performance fails.

In addition, cars now have crankcase ventilation systems (exhaust valves), which can also exacerbate oil consumption if there is a problem.

Precautionary measures for burning engine oil:

1. Use high-quality engine oil

Engine oil is very easy to corrode and age in a long-term high temperature state, resulting in the oil film becoming thinner, and it is easier to escape to the combustion chamber to participate in combustion, so the use of high-quality engine oil can greatly delay this phenomenon.

2. Pay attention to the cleanliness of the fuel circuit

Fuel in the combustion process is indispensable to produce carbon deposits, and carbon deposits are the root cause of some car failures, such as the aging of valve seals, piston wall clearance, etc., all have a direct or indirect relationship with the formation of carbon deposits, considering the relationship between domestic oil products, it is necessary to use high-quality engine oil and (PNF) fuel additives to achieve, which is also the key to achieve no dismantling and repair to solve the problem of burning engine oil.

The hazards of burning engine oil in automobiles and their solutions are as follows:

1. Slight burning: fuel consumption, insufficient power, easy to produce carbon deposits, after carbon deposits, it will be difficult to get on the car, and the engine will shake.

2. Severe burning: The oil consumption is very large, and the engine is very worn. When the oil burns out, the engine will be overhauled!

3. Identification and inspection: the concentration of blue smoke. Pull out the oil ruler often to see how fast the oil is consumed.

Solution: 1. If the old vehicle burns oil, you can appropriately choose to add oil with relatively high viscosity to the engine to increase the tightness between the engine piston and cylinder wall. Of course, the ultimate way to completely solve the problem of burning engine oil is to overhaul the vehicle more thoroughly in order to fundamentally solve the problem.

2. If you find that the vehicle has signs of burning engine oil, you should always check the scale of the engine oil, regularly replace the oil and oil filter according to the requirements of the product instruction manual, and replace the spare parts of the oil filter.

No, burn the oil.

It doesn't have much to do with the oil grade.

The difference between a 0-40 oil and a 0-20 oil is that the high temperature viscosity of the oil is different.

40W is more conducive to maintaining oil viscosity in high temperature areas.

In layman's terms, 0-20 oil is "thinner" than 0-40 when hot, so it will cause a slight decrease in oil pressure.

If you have to measure it numerically, at 100 degrees of oil temperature, 40W is about more than double the viscosity of 20 degrees.

To put it bluntly: if you often use the car at low and medium speeds, 20w is enough, as long as the oil gauge does not show abnormality, there is no problem with use. If you often use the car at high speeds, it should be 30w or 40

The so-called "burning engine oil" is to put it bluntly, the oil enters the combustion chamber, which has a certain relationship with viscosity, but more importantly, it depends on the matching of the piston and the cylinder and the piston ring (including the dislocation of the interval), Japanese cars.

The engine is still relatively passable, so there is no need to worry too much. If you burned the engine oil before, it will not disappear if you change the engine oil, and if you don't do it before, it is unlikely to cause the oil burning failure.

In the face of the situation of burning engine oil, it is recommended not to overhaul first, the result of overhaul is that the original quality of the same parts will be replaced soon after the oil will be burned again, to completely solve the cause of burning engine oil in order to ensure that the oil is not burned after repair, right.

I have comprehensively tested more than 20 different brands of cars that burn engine oil, and more than a dozen brands have tested the conclusions. Many cars change the oil and test the next product when one product doesn't work, until a product that actually works is validated. The results of our test show that the anti-burn engine oil product is the best among the products we can test so far.

Because it was tested in the north and not in the south, I hope that the southern riders can provide more feedback on the effect to help everyone certify a really effective and good product.

In the case of ineffective repair, the hard problem of the accessories is detected, and there is no other way to overhaul and replace it.

Hello, if your engine burns oil, there is no need to overhaul, you check the exhaust valve, turbocharger, piston ring, valve seal, because only these few places can affect the engine burn oil, there is no need to overhaul.

Hope it helps.

There are many factors that go into burning engine oil, and it is not clear to say. Specifically, it is better to go to the repair shop and let the master check, if it is not expensive, it depends on your demand for it.

The poor sealing of the cylinder is the main cause of oil burning. The main reason is that the matching gap between the piston and the cylinder wall is too large, the piston ring is improperly installed or the sealing is poor, and the oil on the cylinder wall enters the combustion chamber, causing the phenomenon of burning oil. Choose good quality engine oil as much as possible, and old vehicles can appropriately choose oil with slightly higher viscosity to increase the sealing between the piston and cylinder wall; Check the oil scale frequently.

The reason why the engine oil burns badly.

The cylinder piston and ring are worn, and the oil enters the combustion chamber to participate in the combustion. This not only increases the consumption of engine oil, but also leads to increased fuel consumption and engine weakness.

Damaged valve guide seals can also cause oil burning.

It is advisable to send it for repair as soon as possible.

If this oil burning, if it is more serious, it will need to overhaul the engine. Check that your piston rings are heavily worn and that your valve seals are not aging.

Answer: Hello, choose a slightly more viscous oil to increase the tightness between the piston and the cylinder wall to solve the problem of burning oil. Of course, the ultimate solution to the problem of burning engine oil is to overhaul the vehicle more thoroughly and fundamentally solve the problem.

1. You may not be able to maintain it in a timely manner or have a problem with your fuel quality. It is recommended that you change the gas station or add some anti-burn and anti-wear agents for daily protection. It can be repaired.

As long as it is the kind of burning oil that is extremely serious and the parts are damaged, it can be repaired. You can check it on the treasure.

2. Don't overhaul first, the car should be repaired first, and then overhauled if the repair is not good. Don't come up and overhaul it, if you don't clean up and solve the cause of the previous burning problem after the overhaul, it will burn later. And the quality of the accessories is the same as before, and it is still burned when it comes to kilometers.

So fix it first, and even if the repair is not successful, it will lay the foundation for the overhaul.

Because the technology is now mature, so it can not be repaired, first repaired in the way of repair, after the repair fails, usually because of the damage to your accessories, the premise of repair is that the accessories are not damaged.

The common problem that Camry can't cure is that the engine oil will burn after about 100,000 kilometers, and there will be 1L engine oil for about 3,000 kilometers. Early Camry piston rings were flawed in their design, and the absence of wave rings led to oil burning. Replacing the improved piston rings can perfectly solve the problem of burning engine oil.

The Camry is a model of GAC Toyota, and in December 2020, it was selected into the list of "2020 Top 100 Fuel Vehicles in the Chinese Market".

In terms of appearance, the eighth-generation Camry has a luxury version and a sports version with dual styling meters, both of which are derived from Toyota's latest "Keenlook" design language. The luxury model features a large trapezoidal bar grille, a streamlined body with a lower waistline and an extended roof rear for more headroom.

The sports version of the model has a three-layer grille front face, and for the first time, it adopts a two-tone body, a "pure black" cabin design, and a two-sided four-exhaust pipe shape at the rear. In addition, the hybrid version is based on the luxury version, with light blue front and rear lights to highlight its identity.

The hybrid version of the model, with its new sports version styling, maintains the main design shape of the current fuel sports version of the model as a whole, and only reveals its hybrid version of the jujube god in some details. Specifically, the front face of the car adopts an X shape, and the inside of its grille is made of black mesh material, and the **Toyota logo is embellished with blue elements, and the effect of the stool is more prominent.

Most of the Camry oil burns because the piston ring is trapped by carbon deposits. Relying on the addition of high-viscosity engine oil to continue life is only an expedient measure to cure the change. The poor power of the engine is due to the fact that the oil participates in the combustion and forms more carbon deposits, which in turn aggravate the degree of oil burning and form a vicious circle.

Excessive carbon deposits will clog the fuel injector, resulting in poor atomization and poor combustion, resulting in higher fuel consumption and lower power. In the long run, it will cause cylinder wall strain, or even cylinder burst, and finally the engine can only be disassembled for overhaul.

Four reasons why you burn engine oil

A ...If you don't clean the oil circuit for a long time or don't do effective oil circuit cleaning, detergents are used at will, and using detergents and effective detergents are two different things;

IIThe antifreeze replacement cycle is too long or not changed at all;

IIIThe oil change interval is too long;

IVLong-term or often short-distance driving cracks.

The above four points of the vehicle that burns engine oil must be occupied by one or all four points.

How the piston rings are stuck

The principle of piston ring stagnation should start from the oil circuit, the oil bearing temperature is 110 degrees, and the oil circuit is not clean for a long time, so that the oil is at a temperature of 120 degrees or higher for a long time, so that the oil will be exhausted in advance, the small hole of the oil ring is very small, and the oil inside will be dried and scabbed for a long time, and a cylinder stuck is 5000 kilometers of a liter of forward rolling oil, at this time, the working conditions of other cylinders will also begin to be bad, and soon 4 cylinders will be stuck. It becomes a liter of engine oil for 1000 kilometers or even hundreds of kilometers. Therefore, in order to solve the problem, we must start from the root oil circuit, which is the way to remove the root.

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. Especially containedThe division of PNF's patented technology has universal non-destructive repairThe product, has completely gotten rid of the technical shackles of the operation of the auto repair shop, without removing a screw, the owner can operate it himself, and the piston ring is repaired and released during driving, and the effect is remarkable.
