replacing engine oil and oil filter on VAZ 2108, VAZ 2109, VAZ 21099 cars

The life of the car's power unit depends on the cleanliness of the motor lubricant. To catch abrasive particles and other debris from the oil, the VAZ 2109 design has a filter.

While cleaning the lubricant, the consumable gradually becomes clogged. Its throughput drops and it ceases to perform its functions normally. To solve the problem, it is necessary to replace the consumable.

It is advisable to perform this simultaneously with pouring fresh oil.

Approximate price and article number of the original VAZ 2109 oil filter

The VAZ 2109 uses an original oil filter with catalog number 21080101200508. It is used on cars that have both a carburetor and an injector. The price of consumables ranges from 190 to 250 rubles. The automaker does not manufacture oil filters on its own, but purchases them from third-party companies. The largest supplier is.

The quality of original VAZ 2109 oil filters is extremely low, which is confirmed by many negative reviews from drivers. The greatest number of problems are associated with the active part of the filter element and the return valve. The filter does not retain oil inside after the engine is turned off. This leads to frequent false alarms of the oil pressure sensor after starting the engine. The warning light often lights up for 4-6 seconds. In some cases, the original filter can cause oil starvation of the power plant, which has an extremely negative effect on its service life.

Another major filter supplier is . Its consumables, packed in original boxes, also have many negative reviews from car owners. The main dissatisfaction is caused by the low quality of the paper from which the active part of the filter element is made.

Poor reliability of the materials used leads to through holes appearing inside the filter during operation. Through them, unfiltered oil with abrasive particles and other debris begins to quietly circulate around the circuit, reducing the service life of the motor.

launches a direct analogue under its own brand. The consumable has article number 21081012005010. The cost of such an oil filter is 150-170 rubles.

The VAZ 2109 has original oil filters with other catalog numbers:

• 2105-01012005-82;
• 2108-01012005-00;
• 2105-01012005-00.

The main difference between the original filters is that consumables with number 2108 are slightly shorter than products with index 2105. Moreover, all filter elements are fully interchangeable. Their cost is in the same price range.

What does a bad filter lead to?

If you do not change the oil filter in time, this will result in the following consequences:

• The oil will lose its original properties and cease to perform its functions. Together with the tasks of preventing friction, it will itself cause increased wear of parts;
• The engine will lose power;
• The heat transfer rate will decrease due to impaired heat removal. The motor will simply overheat regularly;
• The overall efficiency of the vehicle will noticeably suffer.

When choosing a new oil, there are no special problems, since there are recommendations from the manufacturer. It’s more difficult with a filter, since there are many companies and reviews about each of them are sometimes very contradictory. Therefore, you should approach the purchase of an oil filter very responsibly.

Ways to distinguish a fake from an original filter

Installing a fake leads to a reduction in the life of the power unit. Therefore, it is important for a car owner to be able to identify a counterfeit before installing it on the car. To do this, you should pay attention to a number of little things.

The packaging can give away the fake origin of a consumable. The box of a counterfeit oil filter often does not match the size of the consumable, and its color is not so rich. It is important to read all available inscriptions. The counterfeit may have spelling and other errors or inconsistencies. The printed letters must not have typographical flaws. The original packaging always comes without printing defects.

Upon further inspection, it is necessary to check the sealing ring. In the original, it is made of elastic rubber that has no noticeable flaws. A fake ring is made of tanning materials. In this case, the seal often falls out of the seat.

The quality of painting can also reveal a fake. In the original, it is applied using high-tech equipment, so it does not have serious flaws, for example, inclusions of dust. The quality of painting of a fake is usually low; you can often see shagreen, uneven color and other defects.

When identifying a counterfeit, it is important to look inside the filter. On a fake, you can find traces of corrosion, small debris or copious amounts of low-quality sealant.
