Can We Mıx Greases Contaınıng Dıfferent Thıckeners?

The greases containing different type thickeners may be incompatible with each other, thereby problems like deterioration in respect of consistency may arise. You can get information from the technical support team about the compatibility of grease types.

Can We Apply Mıneral Based Greases And Synthetıc Greases To The Same Place?

Information regarding the compatibility must be obtained before mixing mineral based greases and synthetic greases. Even though they’re compatible, mineral based greases may adversely affect the performance of synthetic greases.

How Do We Know The Deterıoratıon Of The Engıne Oıl?

The oil is required to be tested physically and chemically under laboratory conditions.

Is It Necessary To Add Addıvıte Into The Engıne Oıl?

Engine oils are designed in such a manner that won’t need any extra oil additives. Therefore, the use of oil additives may even damage the engine contrary to popular belief. It is also not necessary to add any extra additives to the oils used in transmission, differential and steering wheel hydraulic systems.

Accordion Panel

Tolerance is an expression that refers to the space between two metals which are very close even touching to each other. The engine is enabled to be more compact and to exhibit much more performance by minimizing these spaces with new technologies. The use of finer (synthetic) oils is preferred in new technology engines with contracted tolerances.

Why Does Engıne Oıl Darken And Look Lıke Dırty?

One of the tasks of the engine oil is cleaning. High quality engine oil takes inside the soot generated in the engine thanks to its dispersant and detergent additives through dispersion, prevents sticking on metal surfaces. It cleans those sticking to metal surfaces with detergent. Therefore, engine oil is contaminated. Hence, the engine oil looking like dirty means fulfilling its task properly.

Why Do Engınes Reduce Oıl?

Oil reduction is related to the technology of the engine. Metals (cylinders, pistons) have been designed closer to each other in modern engines produced with new technologies in an effort to provide high performance. This property of the engines causes the oil to be worn, and consequently to reduce. Vehicle manufacturers have specified oil reduction shares for certain km. intervals of the vehicles in vehicles’ booklets. Synthetic lubricants makes less reduction compared to mineral oils.

What Is The Dıfference Between Synthetıc Lubrıcant And Mıneral Oıl

The substances used to separate two solid objects in general and to provide easy movement by minimizing the friction power, are called lubricant or oil.



Automotıve Gear Oıls Apı Performance Class
  • API GL-1: In spiral-bevel and worm gear axles and some straight transmission running under intermediate service conditions
  • API GL-2: In worm gear axles where API GL-1 is not adequate
  • API GL-3: In straight transmission and spiral bevel gear axles running under intermediate service conditions
  • API GL-4: In hypoid gears running under heavy service conditions without shock loading
  • API GL-5: In hypoid gears running under very heavy service conditions with shock loading
  • API GL-6: In the gears exposed to high pressure, running under heavy service conditions
Engıne Oıls Acea Performance Class

The classification is made with a figure following a letter (like A3). ACEA standard is divided into two categories. The first category explains the engine in which the oil can be used:

For gasoline engines A,
For diesel automobile engines B,
For lorry engines C,

Meanwhile, the subsequent number identifies the performance level of oil:
For fuel economy 1,
For general purpose (average level) 2,
For high performance 3.

For example, A3 defines high performance oil for gasoline engines, A1 defines the oil for economy purposes for gasoline engines.

Engıne Oıls Apı Performance Class

The classification is made with two letters. The first letter indicates engines among gasoline (S) or diesel (C) for which the oil is suitable, and the second letter indicates performance value of the oil in the same group. Performance classification is made between A-J for gasoline engines while A is the lowest, and between C-F for diesel engines in both groups. In gasoline engines: (min. performance) SA..SB..SC..SD..SE..SF..SG..SH..SJ (max. performance) In diesel engines: (min. performance) CA..CB..CC..CD..CE..CF (max. performance)

Engıne Oıls Sae Vıscocıty Class

SAE classification classifies the oil according to viscosity at low and high temperatures different from others, therefore it can be said to be somewhat more detailed. The degree in SAE classification is composed of two figures separated by the letter of W. W means winter and indicates the viscosity of oil at low temperature. For example, 15W in 15W-40. At the same time, this is the base viscosity of the oil, i.e. its intrinsic viscosity prior to the addition of polymer. This shows us how fluent the oil will be at low temperatures and how easy the engine will run because the smaller the figure is the finer the oil becomes. The second figure gives the high heat viscosity of the oil. Such as in the 15W-40. As the number increases, so the oil becomes more viscosity, namely thick when it is hot.

Classıfıcatıon Engıne Oıls

The classification of automotive oils has been done by various organizations and the initials of these organizations have been placed in front of the numbers of tests applied to these oils. These classes identify the performance of the oil. These abbreviations with explanations are as follows:
SAE: American Automotive Engineers Union
API: American Petroleum Institute
ILSAC: International Lubricant Standards and Approval Committee
ACEA: European Automobile Manufacturers’ Association
MIL: USA Army Lubricant Specifications
JASO: Japan Automobile Standards Organization.

What Is Synhetıc Oıls?

Synthetic oils are the oils produced by chemists as a result of various chemical processes in laboratories.

What Is Mıneral Oıl?

They’re the oils obtained after distilling the petroleum in refineries.

What Is The Purpose Of Lubrıcatıon?

The substances used to separate two solid objects in general and to provide easy movement by minimizing the friction power, are called lubricant or oil.

What Is Lubrıcant Glossary?

It is obtained by mixing various additives into base oils with different viscosity in order to provide physical and chemical properties expected from the product.
