Motoroils


You do not need to be an expert to add more motor oil to a vehicle. Yet there are a few important things to bear in mind:
- ■Before the motor oil can be added to, the precise oil level has to be established. This takes place using the dip stick (mostly identified by color in the area of the oil filler neck). The vehicle must be on an even surface. To measure, simply pull out the dip stick, wipe off any oil, put it back in and pull it out again. Now the precise oil level can be read and, if necessary, easily corrected.
- ■On the dip stick, there is generally a liter between the marks of MIN. and MAX.
- ■The right oil has to be used. If this is not known, our Oil Guide or our technical support by phone +49 731 1420-871 can help

Lubricants
Good to know
ACEA
The ACEA (European Automobile Manufacturers’ Association) has been the official successor to the CCMC since January 1, 1996. It defines the quality of the motor oils in accordance with the requirements of the European engine manufacturers.
ADDITIVE PACKAGE
An additive package is a mixture of various chemical substances that influence the properties of the motor oil in different ways.
ALKALINE RESERVES
The alkaline reserves of an oil neutralize acidic reaction products, which are created during the combustion of fuel.
API
The American Petroleum Institute (API) determines the global quality requirements and testing criteria for lubricants. Europe or European manufacturers are largely excluded from this.
ATF
So-called automatic transmission fluids (ATF) have a defined friction coefficient and a high viscosity index. The oils are mainly used in automatic transmissions and power steering.
BASE NUMBER
The base number shows the quantity of alkaline reserves in motor oils. In used oils, the base number gives an idea of the remaining additives that have not yet been used.
CRACKING
In cracking, long hydrocarbon molecules are broken up. These broken molecule chains form the base product for synthetic oils.
DISTILLATION
During distillation, crude oil is heated under atmospheric pressure and split into its natural components.
DETERGENTS
Detergents are wash-active substances in the oil, which prevent the formation of deposits or free the motor of them. Also, detergents form the so-called alkaline reserves.
DISPERSANTS
The dispersants contained in motor oil coat solid and liquid contamination in the oil and transport them to the oil filter.
DEWAXING
During dewaxing, wax crystals are removed from the corresponding distillate, in order to improve the pour point (the lowest temperature in which the oil is still flowing when it is cooled under certain conditions).
EP ADDITIVES
Extreme pressure additives (EP) form a “protective layer” on the metal surfaces under high pressure and great heat.
FRICTION MODIFIERS
Friction modifiers (FM) create weak bonds on the metal surfaces and thus reduce or increase the friction properties of a lubricant.
GL
GL means “Gear Lubricant” and identifies the pressure stability of a gearbox oil according to API.
PUMPING VISCOSITY LIMIT
The pumping viscosity limit describes the test for classifying the lubricants into the respective SAE grades. The viscosity of the corresponding SAE grade must not be exceeded at a specified temperature in order to ensure that the lubricant continues to flow automatically.
BASE OIL
Base oil is the base product for the manufacture of lubricating oils. Base oils (mineral, hydrocracked or fully synthetic) are manufactured by various refinery processes.
HTHS VISCOSITY
High Temperature High Shear (HTHS) refers to the dynamic viscosity of a liquid measured at 150 °C under the influence of high shear forces.
HYDROCRACKED BASE OIL
Hydrocracked base oils are manufactured on the basis of paraffin. These oils are currently state-of-the-art and are also used in cutting-edge gasoline/diesel engines.
HYDROCRACKING
During hydrocracking, long molecule chains are broken up in the presence of hydrogen. This hydrogen accumulates at the open chain ends and “repairs” the break.
HYDROFINISHING
Hydrofinishing is the addition of hydrogen during the production of mineral base oil for ensuring optimum aging stability.
JASO
The Japanese Automotive Standards Organization (JASO) divides lubricating oils into various classes and is mainly used in the motorbike sector and in Asia.
CATALYTIC HYDROCRACKING
In catalytic hydrocracking, the molecule chains are cleaved in the presence of a catalyst (e.g. synthetic aluminosilicates) and at a temperature of 500 °C.
LSPI
Low-speed pre-ignition occurs predominantly in modern, low-volume turbocharged gasoline engines with direct injection. Particles or drops of oil heat up when the engine accelerates and form an additional ignition source which ignites the fuel before it is regularly ignited by the spark plug. This leads to “knocking” and up to threefold pressure spikes, which in turn can lead to engine damage.
MINERAL BASE OIL
Mineral base oils are a direct product of crude petroleum distillation. This type of base oil is no longer used in modern motors.
NAPHTA
Naphta is petroleum, which represents a product of crude petroleum distillation.
PARAFFIN
Wax crystals that form the byproduct of the manufacture of mineral base oil are described as paraffin or kerosene.
POUR POINT
The pour point is the lowest temperature at which the oil will just flow when cooled under specified conditions.
POUR POINT DEPRESSANT
A pour point depressant (PPD additive) changes the structure of the wax crystals in the base oil and delays their growth. This minimizes the solidification point of the oil or improves the low temperature property.
REFINING
Refining is the removal/conversion of unwanted parts from vacuum distillates.
BACKWARDS COMPATIBLE
Backwards compatible refers to a specification or release that meets and exceeds the previous (then obsolete) specification or release.
CRUDE OIL
Crude oil is a mixture mainly made up of hydrocarbons, which is created by the decomposition process of organic materials.
SAE INTERNATIONAL
SAE International (formerly the Society of Automotive Engineers) specifies the valid viscosity classes for motor and gearbox oils in the automotive industry, which manufacturers around the world conform to.
VACUUM DISTILLATION
Vacuum distillation further separates residues from distillation under reduced pressure. Through the vacuum, the boiling point can be reduced by approx. 150 °C and therefore the cracking of the molecules is prevented.
VISCOSITY
Viscosity is the resistance (inner friction) of a fluid. The higher the resistance, the more viscous the oil is. The viscosity in motor and gearbox oils is given according to SAE.
VISCOSITY INDEX
The viscosity index (VI) describes the viscosity/temperature behavior of the oil. The higher the VI, the lower the change in viscosity across the entire temperature range.
VISCOSITY INDEX IMPROVERS
Viscosity index improvers are polymers that are designed to influence the temperature-dependent change in viscosity of an oil.
FULLY SYNTHETIC BASE OIL
Fully synthetic base oils are oils based on polyalphaolefin. These are manufactured synthetically and offer high temperature and aging stability.
Crude petroleum was created by dead plankton that sank to the bottom of the seabed millions of years ago. Over the course of time, sand and stones built up on top of it. Due to this impermeable layer and under oxygen exclusion, pressure and heat, the conversion of these "lifeforms" into crude petroleum took place. The basic building blocks of crude petroleum are hydrocarbon compounds, which can occur in various chain lengths (C5 - C100).
Base oils form the base product for the manufacturing of motor oils. The various base oils (mineral, hydrocracked or fully synthetic) are manufactured by various refinery processes (see sketch).


- ■Additives that have an effect on the base oil, e.g. pour point improvers, anti-foam additives or viscosity index improvers.
- ■Additives that have an effect on the material surfaces (bearings, cylinders …), e.g. bonding enhancers or friction modifiers (friction value improvers).




Extreme Pressure Additives (EP additives) are added to the oil in the form of sulfur or phosphorous in order to prevent fusing due to high pressures or loads of the friction partners. In this case, EP additives in lubricants are indispensable. Under high pressures or loads, high temperatures are created in the lubricant. This causes sulfur (sulfur carriers) or a phosphorous derivative (compounds containing phosphorous) to be released from the EP additive. Under these conditions, the released substance immediately reacts with the metal surface to metal sulfides or phosphates. The connections form on the metal surface layers that are sheared off under the high pressure, with which a fusing of the metal surfaces is prevented.


The PPD additive is used to reduce the solidification point of the lubricant and therefore improve the low temperature properties. The wax crystals included in base oil are changed in their structure by the additive and their growth is significantly slowed down at low temperatures.


Viscosity index improvers are macromolecular polymers (combination of macromolecules) that are constructed in such a way that they influence the temperature-dependent viscosity change of an oil. The polymer contracts at low temperatures. This makes the resistance that the polymer opposes an invading body with smaller and the viscosity change of the base oil is equalized..


.


The viscosity gives only information about the inner friction of a motor or gearbox oil and therefore does not define any kind of qualitative properties. This means that a motor oil that fulfills a viscosity as per SAE has a prescribed flow behavior at various temperatures. The viscosity is divided into the cold start range (e.g. 0W) and the operating temperature range (e.g. 30). The higher the given figure, the more viscous the motor/gearbox oil is in the corresponding temperature range. The letter "W" identifies the winter suitability of the oil (multi-grade oil). If this addition is missing, then the oil may only be used in summer.
Up to which low temperature a motor/gearbox oil can be used depends on the flowability in the limit temperature range. The deeper the expected temperature, the less viscous the oil has to be.


The American Petrol Institute fundamentally differentiates between two different types of motor oil: On the one hand, motor oils for gasoline motors (S), on the other, motor oils for diesel motors (C). The letter following the first letter, e.g. "G" or "H", defines the quality of the lubricant. The later in the alphabet this letter is, the higher quality the motor oil is. The higher classifications such as API SN can be used by API for the preceding classifications without hesitation, e.g. API SL. For motor oils for diesel motors a "4" can additionally be displayed. This addition identifies the suitability for large motors such as trucks or buses (heavy duty).

In order to at least be able to get a general answer as to what quality or which properties a gearbox oil corresponds to, over the course of the past few decades, division into by API for manual gearbox and axle drives and by Dexron for automatic gearboxes. The manufacturers made use of this division over a long period of time. After the gearbox became ever more complex, however, this division was no longer sufficient. The viscosity of the manual gearbox and axle drive is – as with motor oils – classified by SAE. The viscosity of automatic gearbox oils, so-called ATF oils (Automatic Transmission Fluid), is not classified by SAE, as the viscosity is a part of the respective manufacturer approval.
9.1.1 API (manual gearbox or axle drive oils)
GL 1 | low load hypoid or worm gearbox | 0 % additives |
GL 2 | Worm gearbox (not in road vehicles) | up to 1.5 % additives |
GL 3 | Manual gearbox (vintage) | up to 2.7 % additives |
GL 4 | Manual gearbox, hypoid gearbox if permitted | up to 4 % additives |
GL 5 | Hypoid gearbox, manual gearbox if permitted | up to 6.5 % additives |
9.1.2 GM Dexron (automatic gearbox)
