For Worriless Output Of Black Audi A5 For Sale Continual Care Is Essential
The gearbox oil is certainly one of the very avoidable aspect s by the owner of the black Audi a5 for sale as well as by also by repairers and this is because of ignorance and because it is complicated to carry out the level controls ends up in oblivion. Yet gear oil is a very important component to keep the car running efficiently. What kind of oil do you need to use? How many kilometers should be replaced to preserve the wear and tear of the most stressed parts? Let's try to understand together what it is used for and what features it must have.
The Ideal Characteristic
The gear oil has a double function; the first is to reduce the friction, the second is to dissipate the heat that is generated precisely because of the friction itself. The reduction of friction occurs because the oil adheres to the mechanical parts interposing between them, creating a thin layer and therefore limiting contact to a minimum. It goes without saying then that the ideal characteristic of the oil is to be able to create a layer as often as possible. As for the high temperature, this could lead to a reduction in hardness of the superficial part of the teeth of the ratios that make up the gearbox and therefore the oil should easily remove the heat from the gears, preventing the wear visible in the image attached at the top. To prevent the metal fragments in the oil from causing further damage, the cups are equipped with magnetic elements or plugs on which the debris accumulates when the gears are worn. If a considerable amount of filing is present at a mechanical inspection, as in the image attached below, this is not a healthy indicator of the health of the gearbox.
The Viscosity Of The Oil
In the specific exchange oils, generally of mineral origin, a series of additives are added to reduce the risk of corrosion (anti-corrosion and anti-oxidation additives), reduce the deterioration of performance (anti-foaming agents), and reduce wear (a bit like engine oil, find out all the details here ). As for automatic gearboxes with torque converter, the type of oil, specifically named ATF(Automatic Transmission Fluid) should assure superior performance. The viscosity of the oil, for example, should very little due to large temperature changes and above all it is necessary that the oil is equipped with excellent cleaning properties since, if necessary, deposits, once they have collided the gearbox control valves, would produce an immediate adverse effects of the gearbox as these could no longer work properly. Then having to pass also for the torque converter, which will centrifuge the oil, it is clear that the ATF oil should assure remarkable anti-foaming properties.
The Point Of View
in the perspective of the ordinary maintenance of manual transmissions, the tendency of the manufacturers is not to provide for a replacement but only to verify and restore the level. Gearbox oil is to be replaced only when the mechanic considers it necessary during the check. The fact that replacement is not foreseen by now makes us think about how the quality of the transmission oil has improved. On the other hand, the gear oil, unlike what happens for the engine oil, is not subjected to carbon residues due to combustion which contaminates it and therefore can last longer. With regard to automatic transmissions, the oil instead should generally be replaced. DIY activities are largely discouraged (especially for automatic transmissions with torque converters). For this component always contact a professional and as regards automatic transmissions always choose professionals specialized in that type of transmission: on automatic transmissions, in fact, even the level control requires complex procedures. Do not even over or under use on oil, a poor quality could lead to expensive breakages.
