During operation of the vehicle, over time the oil ages and loses its properties. Old oil increases wear on the car units and reduces their service life. Also delayed oil change at all able to bring the car down, and at times to increase the cost of its repair. Thus, for normal vehicle operation requires timely replacement of oil in all its units.

How often to change oil

Disputes on the subject do not cease for a moment, debating about everything from car owners with auto masters to car manufacturers and oil. There is a myth that the oil in the engines of modern cars, should be changed approximately every 5 th. Kilometers. So it was before, modern engines in cars have become significantly eco-friendly, cost-effective and compact, and the timing of replacement of oil have changed considerably. The same applies to oils directly themselves, manufacturers add various additives in modern oils that increase their lifespan.

Timing services oil, depends from many different factor - a model and make of the car, the quality of the oil itself, driving style of the vehicle owner and the vehicle operating conditions. For example if the vehicle engine is regularly running at high speed and with a jerk is started, the oil replacement should be more frequent than with a smooth, quiet ride. Also, the oil will last longer if the car is used for long trips outside the city.
First of all, when an oil change should be guided by the instruction to the car, there is a detailed regulation of all such jobs. On the basis of these instructions, as well as the operating conditions of the vehicle and should replace the engine oil. For different vehicles as possible replacement of oil in the manual, may be quite different and can vary from 5 thousand. To 50 thousand. Kilometers. It all depends on the make, model and model year of the car. Ideally, it is worth making a check engine oil quality, it will help identify the needs to be replaced or not.

Important! To the car's engine was working properly long period of time, should be used only high-quality motor oil. The engine runs on regular low-quality motor oil, on average, requires major repairs over 20-50 thousand. Kilometers.

How to check the quality of motor oil

To check the oil, we need only gloves and a small sheet of paper.
Before checking the oil, the vehicle engine must be warmed up 5-10 mine. When the car is warmed up, you need to remove the dipstick for oil and oil to drip onto the paper. Now we need to drain the oil contained in the paper, the heater can be used for this purpose. On average, oil drying takes 1-2 hours. When the oil has dried, you can begin to evaluate his condition.

When checking lubricant should pay attention:

• The drop is a black or dark gray, dark brown color. Such oil color means that it must be replaced immediately;
• In oil extraneous particles present a black color. The presence of these particles indicates an extremely high contamination of the engine oil;
• The metal particles in the oil, indicate the onset of destructive process in the engine.

So for the evaluation of motor oil you can use the following table:

Balls in the table mean:

• 1-3 marks are talking about good condition of engine oil;
• 3-5 points indicate a good condition of engine oil;
• 5-7 points speak about a satisfactory condition of engine oil;
• 7-8 balls talking about the poor quality of the engine oil;
• 8-9 say about the critical-low quality engine oil.

How to change the oil, progress in stages

oil changes must be made in conjunction with the replacement of oil filter. Substitution takes place in the following order:

1. The first step merges the old engine oil;
2. Further, changing oil filters;
3. The final stage should fill fresh oil.

instruments assistants in

When changing the oil and oil filters will need the following tools:

1. Wide capacity, which we will directly pour oil;
   Rubberized gloves, they will protect your hands from possible burns and extremely harmful waste engine oil;
2. A standard set of keys;
3. Special puller for the oil filter (if no, you can try to unscrew by hand or use a large screwdriver).

how to drain the oil, progress in stages

When replacing the car engine oil needs to be warmed up to operating temperature and seal it. If the vehicle has just been in operation it must stifle and cool 10-30 minutes, so as not to get burned. To drain the oil from the engine, we need a suitable container.

Important! Heat the oil needed to make it more liquid.

To drain the engine oil is necessary to put the car rack or a viewing hole. Drain the used oil in the following order:

1. The first step is to open the hood and remove the oil filler cap hole;
2. The next step is to remove the protection crankcase and a mudguard of the engine;
3. Container ready for oil, you can easily unscrew the cap from the drain hole on the crankcase (the lowest point on the pallet);
4. Oil will flow at once, so capacity should be substituted in advance. Okruchivaet original key, and then hand;
5. Now you need to wait until the oil drains, it usually takes no more than 5-7 minutes. I should say that absolutely all the oil from the engine will not turn out to merge, will be approximately 2-4% in it.

Drain oil assess its immediate condition. As we conclude, whether the engine needs washing.

replacing the oil filter, progress in stages

Draining of used oil by the above method can proceed to the bay of fresh motor oil, but before it is necessary to replace the oil filter. The oil filter is changed at every oil change.
Filter replacement is done in the following sequence:

1. Change the oil filter is most easily performed using a special puller. When his absence you can try to unscrew the filter by hand or punch a hole in it, insert the screwdriver and use it as a lever;
2. New oil filter before installing it is necessary to fill 30-40% of the fresh engine oil;
   You should also lubricate the O-rings with fresh engine oil, in case if it is not made by the manufacturer;
3. It remains only to screw the new oil filter (screwing only be by hand).

sink old butter and replacing oil filter, you can directly fill fresh engine butter. It does not forget previously close the drain hole on the crankcase. Gulf of fresh oil, screw cap oil filler hole, start the car and give it to work on single passages minutes 5. At this time, we make visual inspection for oil leakage. If everything is in order is put in place and protect the mudguard.

Safety in the oil change

Change the oil should be done with extreme caution. We should not pour oil when it is strongly heated it with a high probability of resulting in burns.
When draining the oil, wear rubber gloves, old waste oil is extremely harmful, it can lead to various skin diseases, even skin cancer.

Important! Should not be measured directly by the temperature of the oil drain plug temperature. The oil temperature is always much higher tube temperature.

How to replace oil in the PPC

Change the oil in the gearbox should also produce on the heated car. Changing the oil in gearbox does not require considerable effort and quite a force to each car owner. Changing the oil in the PPC in the following order:

1. The first step is removed crankcase;
2. Filler plug turns CAT holes;
3. Now you need to substitute a container under the waste oil and unscrew the drain plug CPR;
4. Draining the used oil, spin drain plug;
5. Fill the new oil, if access to the filler opening is problematic, you can use a funnel to put on her hose;
6. Bay new oil, set everything in its place.

Important! There are such a transmission, in which the oil is poured one-time at the factory, and serves the entire vehicle service life.

Why oil loses its characteristics, causes

Over time, the unburnt fuel particles enter the oil, water, gas, dirt and metal particles. With increasing running amount of these components in the engine oil increases, the oil in addition regularly exposed to high temperatures. All this adversely affects the properties of the engine oil, it loses its viscosity and additives fail to fulfill their roles.
Let us examine in detail the reasons why the oil loses its properties:

• use of the vehicle;
• Driving driver manner. Sharp accelerations and braking negatively affect the state of the oil;
  Poor-quality fuel;
• Directly the condition and age of the car.

Fake motor oil

Today on the market for cars, there is a fairly large percentage of fake, low-quality engine oils. Usually they are a mixture of cheap engine oil for trucks and industrial oils. In the manufacture of this mixture, its viscosity is adjusted for the engine oil for which it will be issued.

Also unscrupulous manufacturers are often saved on additives. Additives are the most expensive components of the engine oil, their cost can exceed 50% of the total cost of engine oil, and the immediate share in the composition of only 10%.
Thus, for example, the cost of mineral lubricant averages 6 dollars per liter, and synthetic 17 dollars. To the oil selling much cheaper, it is worth treating suspicion. Also, it is not necessary to purchase the oil on which there is no plug-filling or a low-quality label.
Sub-quality engine oil can lead to the following problems:

• At high temperatures, the engine oil becomes too liquid, as a result, it is worse than lubricated, which significantly increases engine wear;
• In the cold season, the car engine simply does not start;
• Very strong engine contamination occurs;
• The car engine begins to undergo corrosion.

Tips of professionals

• The oil change should be replaced on a warm engine, but in no way hot.
• When replacing the oil, it is necessary to use rubberized gloves.
• When replacing the oil, it is also worth considering the engine type so, for example, in a diesel engine, the life of the engine oil is less than 1.5 thousand kilometers than gasoline.
• The lower threshold of high-quality engine oil is considered to be 5 thousand kilometers.
• In a car, which is regularly operated in urban environments, the oil replacement should be carried out more often than a car riding long distances.
• Only high-quality engine oil should always be poured into the car.
• Various additives in engine oil should not be added.
• With a duty downtime, the engine oil must be replaced.
• The replacement of the oil filter occurs in a pair, with the oil change.
• In the absence of a special key to replace the oil filter, you can use a large screwdriver.
