What is the purpose of lubrication?

The purpose of lubrication is to reduce friction by separating the two surfaces, to facilitate movement by making the surfaces slippery, to make cooling, to minimize wear by forming a film between the surfaces and to prevent corrosion.


What comes to mind when it comes to viscosity?


Viscosity is the measure of the fluid's resistance to flow. It is called as flowability. Thanks to the viscosity, an oil film is formed between the two surfaces under pressure and the system parts are operated for many years without abrasion.

What should be considered when changing the engine oil?

The vehicle must be in the 'stop' position and on a flat surface. The engine oil must be drained while it is hot. Make sure that the old oil in the engine crankcase is completely drained. If the oil has been drained by opening the sump plug, it should be ensured that there is no oil leakage after the plug is replaced and new oil is filled.


What does it mean if the oil used in the engine turns black?


One of the duties of engine oil is to keep the systems it operates clean. A quality engine oil, thanks to its detergent-dispersant additives, disperses the soot particles formed in the engine and prevents them from sticking to metal surfaces. Therefore, the engine oil gets dirty and its color darkens. Therefore, the engine oil that looks dirty means that it is doing its job well.

How do we know if the engine oil has gone bad?


In order to understand exactly whether the engine oil is defective or not, the oil should be analyzed physically and chemically under laboratory conditions.

What is the difference between synthetic oil and mineral oil?


Synthetic based oils are oils obtained by chemical means. They are produced in order to be able to lubricate in applications where traditionally obtained mineral oils may not be sufficient in terms of performance. Synthetic-based oils provide superior protection at higher temperatures, easier fluidity and pumpability at low temperatures, more stable film strength under extreme pressure and longer change intervals under difficult operating conditions.

What are synthetic oils more expensive?


Since synthetic oils are produced with advanced technology and through very complex processes, their cost is higher than mineral oils. This affects the price of the product.


What is oil performance and how do we know it?


The information written on the oil package contains important clues about the performance of the oil. In general, there should be information on 5 subjects on the packaging. These; brand, content (mineral, synthetic or synthetic based), viscosity class (such as 5W-30, 10W-40), international performances (such as API CK-4, ACEA C3), OEM performances (MB-Approval 228.51, Volvo VDS- 4, such as VW 504 00/507 00)

What does OW mean?


'0W refers to the viscosity class of the engine oil. The 'W' stands for Winter and the '0' on the left shows the cold working conditions of the engine oil. That is, the kinemetic viscosity of a 0W motor oil at 100 ° C is at least 3.8 cST, and it is pumpable even at -40 ° C.


What does GL-5 mean on gear oil packs?


It is the API classification used for automotive gear oils. It is a gear oil in accordance with MIL-L-2105 D specification, containing additives that meet extreme pressure and impact loads for hypoid gear type differentials operating under heavy conditions. Extreme pressure additive is higher in API GL-5 and is generally used in heavy operating conditions. Unless otherwise stated, API GL-5 should not be used where API GL-4 is recommended. Because excessive pressure additives in API GL-5 can corrode yellow metals.

Does the mineral or synthetic state of engine oils affect the oil change mileage?


Synthetic oils have superior properties compared to mineral oils in many respects. Long life is one of them, and in general it can be said that synthetic oils provide longer oil change intervals than mineral oils. However, oil change intervals are determined by vehicle manufacturers (OEMs) after a series of tests, compliance with these change intervals is the most appropriate for the health of the equipment.

How should the waste motor oils be used?


PETDER, waste motor oil collection organization serving with Turkey's four corners and the amount of bonus regardless of distance. Waste producers can contact PETDER as the Authorized Institution to obtain information or to collect the waste motor oil they have accumulated in accordance with the regulations. they can be reached. Collection operations are monitored via satellite with central planning, and are carried out with vehicles and trained personnel in accordance with European Union Standards.


Where is grease used?


In places where oil lubrication is not possible in terms of application, grease is used especially in rolling bearings.
