Motoroils

No! You can, of course, always use the matching LIQUI MOLY product.

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

 

 

The oil level of the motor must always be correct, as both too little and too much oil can lead to serious damage of the motor. If you add too much oil, this can lead to the creation of many air bubbles. These air bubbles are then sucked by the oil pump and moved through the motor to the lubrication points. As air famously does not lubricate, greater wear is generated at the areas of friction to be lubricated, which can lead to motor damage.

A further problem of overfilling is increased oil pressure. This can lead to seals, which are supposed to keep the oil in the motor, being torn from their actual position or damaged and therefore the motor becoming leaky.

 

The acronym API stands for American Petroleum Institute. It sets the global quality requirements and testing criteria of lubricants, such as motor or gearbox oil.

The question of which motor oil is suitable for diesel motors keeps coming up, again and again. But the times in which there were special motor oils for diesel motors are long gone. Modern motor oils fulfill both the requirements of petrol and diesel motors. What's important in the selection of the right motor oil is much more the specification or approval given by the vehicle manufacturer. If this is printed on the bottle label, then the oil can be used for the respective motor. Regardless of whether it's diesel or petrol.

If a vehicle is mainly used for short journeys, this has the consequence that the condensation created by temperature differences mixes with the oil and does not evaporate. This oil/water emulsion is then deposited in the entire motor. This becomes visible at the oil filler cap in the form of light-brown sludge. In order to free the motor of this, LIQUI MOLY offers the oil sludge purge.

The color of a motor oil provides no conclusions regarding quality or age. There are, therefore, chemical additives that superimpose on the actual color (amber) of the oil and therefore make it appear darker.

There is no general answer to how often a motor oil has to be refilled. Oil consumption can vary greatly even with motors identical in construction. If there is no oil level control fitted, the oil level should be checked every time you refuel and correspondingly reacted to.

What's important in the selection of the right motor oil is the specification or approval given by the vehicle manufacturer, which can be found in the operating manual of the vehicle. If this is printed on the label of an oil, then this oil can be used for the respective motor. If you are not sure about this, our Oil Guide or our technical support by phone +49 731 1420-871 can help.

The fill level of the motor oil is always measured when it is warm. This ensures that the motor is in the temperature range in which it usually is, optimally supplied with lubricant.

Fundamentally, the recommendation of the manufacturer should be followed when selecting the oil for snow blowers. However, experience shows that our Special Tec LL 5W-30 covers the majority of snow blowers available on the market.

We keep receiving questions like "what do you think of a motor oil change after as long as two years?". Without a sound laboratory analysis of the old oil, the car driver cannot assess the condition of a motor oil by the color or by rubbing it between their thumb and index finger. When a change of the lubricant is necessary is decided either by the vehicle itself (variable) or the change was set by the manufacturer according to a fixed mileage or age. In the case of a variable change interval, the vehicle will tell you when a change is required. The mileage until the next change can simply be called up in the vehicle menu. Should a change be prescribed, the date is usually written on the oil note in the motor compartment or in the service booklet of the vehicle.

A definite yes! Modern motors are highly complex mechanical assemblies. Due to the high requirements expected of them they require a lubricant aligned to the materials and properties. If it does not receive this, the increased friction may lead to motor damage.

As there are soot deposits in the oil circuit particularly in diesel motors, but also in petrol motors, the oil is often colored black after the first few revolutions of the motor. However, this is no reason to panic, as the oil is doing what it should: It is cleaning! While doing so, it is absorbing the soot deposits in the motor and then transporting it to the oil filter.

The minimum durability in small containers is five years – assuming it is stored in a dry place at temperatures between + 5 °C and + 30 °C and is not in direct sunlight. The cellar, and not the garage, is ideally suited to storage.

Fundamentally, the specifications of the gas system manufacturer and the motor manufacturer should be observed. If the vehicle manufacturer approves more general specifications (e.g. ACEA C2/C3 or C4), then low ash oils according to this specification are to be preferred during gas operation. Furthermore, Cera Tec as an oil additive for gas-operated motors is of a fundamental advantage. A dose of 7% to 8% in the motor oil is optimum.

Two-stroke oil dissolves fully in fuel and does not become separated even after an extended storage period.

What is decisive for the selection of an oil is the quality and the manufacturer guidelines, not the viscosity. This information can be found on the container label. The 5W-30 specification relates only to the liquid condition of an oil at a certain temperature and is not a sign of quality.

Yes! The mixability of the motor oils with one another must be possible in order to guarantee refilling at any time. However – depending on the oil added – the quality or the properties of the existing oil are changed.

Motor oil has molybdenum disulfide added to it. This anthracite-colored additive superimposes on the "normal" color of the oil.

The mixability of modern motor oils with one another, regardless of the type, must be possible under any circumstances. For it is not always guaranteed that the average car driver will know which motor oil was used by the garage in an oil change.

Additives

Yes, this has been tested by a field test with company cars. The oil additive minimizes friction by approx. 30%.

Yes, our additives are aligned to one another in their formula in such a way that they do not negatively influence themselves and the overall mixture. However, the dose specifications have to be observed, of course.

Yes, as Motor Oil Saver contains softeners and viscosity improvers. It regenerates elastomer seals and has a slightly viscosity increasing effect at high temperatures. This creates a more efficient lubrication in turbo charger bearings.

No, with these fuels there is no improvement of the low temperature resistance.

When using conventional summer diesel fuels, which have a low temperature resistance of 0 °C, an improvement to -6 ° to -8 °C is achieved when meeting the dose of Diesel Flow Fit.

For clutches that run in oil baths, 20 ml of additive can be added per liter of motor oil. This ensures there is no clutch slippage. Using Motor Protect on clutches running in oil baths is generally not recommended.

Yes, Motor Protect can be used in modern Longlife oils such as Synthoil Longtime Plus 0W-30 and Synthoil Longtime 0W-30.

The use of Motor Oil Saver in motors with clutches running in oil baths can lead to clutch slippage due to the additives contained therein. In this case, we do not recommend its use.

Generally, yes. However, LIQUI MOLY has a special motorbike program in which this formula is specially aligned to the lower tank volume of the motorbikes.

Lubricants

Two-stroke oil dissolves fully in fuel and does not become separated even after an extended storage period.

No! HLP oils are hydraulic oils and are not intended for use in power steering. In the worst case this can lead to a failure of steering – particularly in low temperatures. Therefore please always observe the manufacturer approvals and requirements, as the steering is a safety-relevant component.

Yes!

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).

Mineral base oil is the simplest and oldest form of base oil. In manufacturing the already described crude oil serves as a direct base product. The crude oil is heated in a furnace and disassembled into its natural components (distilled). Then unwanted and damaging components are removed from the distillate by the refining process or by dewaxing. Thanks to the subsequent hydrofinishing, the raffinate specifically has hydrogen added to it, which closes the open molecule chains and therefore significantly increases the aging stability.

Fully synthetic base oil is mainly characterized by its very good thermal stability and cleaning performance. As high performance as it is, so laborious its manufacture also is. So-called naphtha (petrol without additives) serves as the base product. Naphta in cracked in the first step, which means that the molecule chains (C5 – C12) split open and are broken down to a length of C2 – C3. The former liquid is now gaseous. In the consequent synthesis process the short molecule chains (C2 – C3) are added to long molecule chains (C20 – C35) and sealed by adding hydrogen (hydrogenation).

Hydrocracked base oil combines the positive properties of mineral and fully synthetic base oils with one another. This base oil type offers a very good thermal stability and resistance to aging with simultaneously absolute material compatibility. The basis for hydrocracked base oils are formed by the paraffin taken from the mineral oil extraction. The paraffin is made up of long-chained molecule compounds (> C35). These are split open in the presence of a catalytic converter under a pressure of 70 - 200 bar and temperatures of up to 500 °C and shortened to a useful length of C20 – C35 (catalytic hydrocracking). The liquid in the vacuum is subsequently distilled, in order to avoid the cracking of the molecule chains. In the last step, any paraffin deposits are removed

In most cases the base oil alone is not sufficient to cover the many tasks that an oil has to fulfill in a motor, for example. For a reliable lubrication and seamless operation the base oils of additives are added. With the help of these additives, certain properties of the oil can be improved or completely new properties achieved. The list of the additives used for this is varied and long. The individual materials are, depending on the requirement, comprised in an additive package. This package added to the base oil heated from 40 °C to 60 °C and is stirred until it is completely dissolved in the oil. In modern motor oils the concentration of additives can be up to 30% or less than 1% in gearbox oils.

 

Fundamentally, you can differentiate between two types of additives:

    ■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).

    Here is a list of the properties of an oil that can be influenced by additives:

    Detergents are wash-active substances in the oil, which prevent the formation of deposits or free the motor of them. If these are used up by exceeded oil change intervals, for example, the result is the increased formation of deposits (see picture). This causes friction to measurably increase in the motor, risking motor damage.

    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..

    An unwanted byproduct of circulation lubrication is the inclusion of small air bubbles in the motor oil. Anti-foam additives cause a significant reduction of foam created in the circulation of oil (air pockets).

    In order to select the correct motor oil, two pieces of information are required. Firstly, the viscosity, and, secondly, the quality is required. Numerous organizations have arisen over the past few decades for these classifications:

    ■SAE (Society of Automotive Engineers)

    ■API (American Petrol Institute)

    ■ACEA (Association des Constructeurs Européens d’Automobiles)

    ■ILSAC (International Lubricant Standardization and Approval Committee)

    ■JASO (Japanese Automotive Standards Organization)

    The well-known European vehicle or motor manufacturers (Mercedes-Benz, BMW, VW …) conform to SAE for viscosity information and ACEA for quality information.

    The motor oils to be used for import vehicles that were developed outside of Europe (Toyota, Mitsubishi, Chrysler ...) mainly conform to API or ILSAC and SAE.

     

    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).

    The Association des Constructeurs Européens d`Automobiles forms the oil standard for European vehicle or motor manufacturers. Here – as with API – oils for petrol motors (A) and light diesel motors (B) are differentiated. Unlike with the API, at the ACEA every category has its own meaning and cannot be used backwards compatibly.

     

    5.3.1 Car petrol and diesel motors

     

    A1/B1High-performance motor oil for petrol and diesel motors, so-called fuel economy motor oils with particularly low High Temperature High Shear viscosity (2,9 - 3,5 mPA*s). Reserved for viscosity class xW-20. Invalid since 12/2016.
    A3/B4  High-performance motor oil for petrol and diesel motors, extends and replaces conventional motor oils like ACEA A2/B2 and A3/B3 and can be used for extended change intervals.
    A5/B5 High-performance motor oil for petrol and diesel motors, so-called fuel economy motor oils with particularly low High Temperature High Shear viscosity (2,9 - 3,5 mPa*s). Reserved for viscosity classes are xW-30 and xW-40.

In order to achieve a manufacturer approval for a certain oil, in addition to the respective ACEA/API test procedure, further motor tests and requirements must be fulfilled. An overview of which manufacturer specification is based on which ACEA/API classification is shown in the illustration below.

    In motorbike motors the manufacturers largely forgo their own oil specifications and use the API or JASO determined motor tests for determining oil quality. In addition to determining the oil quality, for motorbikes that are equipped with clutches running in oil baths (wet clutch), higher requirements of shear stability, burning behavior and, above all, friction behavior have to be fulfilled. Whether an oil fulfills these properties can be found out via the JASO specification, which has to be listed under the approvals.

     

    Approvals for motorbike motors by JASO

     

    JASO MA(2)4-stroke motors – high friction value for motorbikes with wet clutches
    JASO MB4-stroke motors – low friction value for motorbikes without wet clutches
    JASO FB   2-stroke motors – low cleaning, incomplete combustion
    JASO FC 2-stroke motors – high cleaning, almost complete combustion
    JASO FD2-stroke motors – highest cleaning, complete combustion

    In order to be able to ensure a malfunction-free operation, modern gearboxes require a modern high-performance lubricant, which protects the gearbox against friction and, at the same time, does not affect the shifting characteristics. The type and quantity of additives in the lubricant has a significant influence on various parameters, such as the shifting capacity, the change interval, the friction behavior and the wear protection. It is therefore urgently necessary that the classifications or approvals given by the manufacturer are upheld upon changing the gearbox oil. There are as many gearbox oils as there are types of gearbox. They are first roughly differentiated by manual gearbox or axle drive, automatic gearbox and dual-clutch gearbox. Within these upper groups there are various subgroups, which each need a special lubricant aligned to the construction type and purpose of use. In gearbox oils there is no uniform basis that the manufacturers are obliged to uphold (e.g. ACEA). This leads to a variety of special manufacturer approvals.

     

    EXAMPLES

     

    Mercedes-Benz:

    24 ATF approvals (MB approval 236.x)

    21 (Hypoid) gearbox oil approvals (MB approval 235.x)

    Volkswagen:

    14 ATF approvals (G 052 xxx, G055 xxx, G060 xxx)

    15 (Hypoid) gearbox oil approvals (G 052 xxx, G055 xxx, G060 xxx)

    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.
