ADDITIVES 3 - Oil additives
With increasing age, the interior of the engine and thus also its performance is impaired by friction and/or wear. In addition to the development of mechanical alterations, seals also get porous. Typical consequences are a loud engine noise and/or a slight loss of oil.
Engine oil additives are used to enhance the oil viscosity according to the type of application in order to achieve an increased quiet running of the engine via better lubricating properties. Specific additives (softeners, refreshers) make gaskets swell again and/or make them elastic.
For the users, the advantage may be a better running behaviour of the engine and/or a sealing of minor leakages without expensive shop works.
