Polysilicones (silicone polymers), polyethylene glycol ether and others reduce the foaming tendency of an oil. This is achieved by trapping fewer gases (air and combustion gases) in the oil. On the other hand, trapped gases can escape from the oil more quickly. Foaming significantly impairs the lubricant properties (oxidation, pressure behavior) of a lubricant. A lubricant with poor foaming behavior can lead to significantly higher oil temperatures, wear and...
Dispersants have the task of enveloping solid and liquid contaminants that are introduced into the oil during engine operation and keeping them finely distributed in suspension. This prevents deposits in the engine. A distinction is made between two active processes: Peptization: This refers to the coating and suspension of solid contaminants in the oil, such as....
Detergents are washing-active substances that counteract the formation of deposits on thermally stressed components. They keep the engine clean. In addition, they form the alkaline reserve in the engine oil, i.e. acidic reaction products from combustion are neutralized.
Lubricating oils tend to age (oxidation) under the influence of oxygen and heat. This decomposition process is further accelerated by acidic reaction products from combustion and traces of metals that have a catalytic effect (abrasive and corrosive wear). The addition of antioxidants provides significant protection against ageing. The ageing process, oxidation, cannot be prevented by this, but it can be slowed down considerably. ...
Synthetic esters are chemically produced compounds from organic acids and alcohols. Depending on the desired property of the ester, defined molecular structures can be synthesized. (Synthetic ester has a viscosity index of 140-180).
Polyphaolefins are synthesized from ethylene as the basic building block in a chemical process. The hydrocarbon compounds resulting from this process have a previously defined molecular structure. (Polyphaolefins have a viscosity index of 130-145.) Process: ethylene => synthesis => polyalphaolefin
The starting product is the long-chain (solid) normal kerosenes from the dewaxing of raffinates. The kerosene molecules are broken down (cracked) into shorter lubricant molecules in special cracking plants in a hydrogen atmosphere using special catalysts. As a result of the process, mainly branched hydrocarbon chains (isoparaffins) are produced. In the subsequent vacuum distillation process, the isoparaffins are separated according to viscosity and the remaining unbranched hydrocarbon chains (normal kerosenes) are...
MATHY protects your engine You should consider the following information on the subject of "E10". If E10 fuel is predominantly used, a proportion of 10% MATHY-M engine oil additive should be added to the engine oil. Short-distance driving If you frequently drive short distances (less than 25 kilometers), both the oil level and the oil condition should be checked regularly for changes....
It's quite simple to get to the point: Today's fuels, whether gasoline or diesel, are better for the environment, but worse for the engines! The reason for this is the bio-content prescribed by law or by the EU in all current fuels, i.e. there is currently no fuel without bio-content! Even the...
