On the market they are also available engine oils intended for engines with unit injectors. This type of injection requires special oil, since oil lubricates injector demanding drive system. They should remember in which owners of cars with engines from VW Group (Volkswagen, Audi, Seat and Skoda). Oil is specially reinforced in order that oil film protects this injector drive system was stronger and withstand very large pressures occurring there. It is worth remembering that oils suited to motors with unit injectors are more resistant to breaking this oil film, which does not prevent use of their engines do not have this kind of fuel injection system. Noteworthy is the difference in the selection of motor oil trucks or cars. None of them must not be used in another request than that to which it can be dedicated. Advanced oils truck may be operated even by a lot more than 100 thousand. km, as perfectly cope with plenty of soot and must make use of the properties of the chemical package. The motor truck carries a sump with a capability of 35-40 liters, so the oil jogging at lower temperatures than in the passenger car, and the engine speed are at or below 2, 000, rather than 6000 or perhaps 7000 rev / minute. Requirements for diesel traveler cars are better when it comes to operating temperature, the size and complexity in the whole engine and all the different parts of the lubrication system. Another very important system occurring in each vehicle could be the gearbox. Because these constructions are significantly different from each other, the choice of lubricant in this instance is more complicated. Looking at the manual transmission will notice quite a few requirements that must end up being met, and they are grouped as with regards to motor oils. The oil viscosity must be exactly as you need manufacturer, because it was her first responsible for the correct operation in the synchronizers. It is also important quality in the oil, which is highly varied regarding construction. The most commonly utilised quality classification is API GL, which speaks of the classes in the lowest GL-1 to the highest that is used in the automotive industry. API GL-5. Sorry, we cannot say that each higher classification complies having an earlier. API GL-1 to the API GL-4 are known for gearboxes and quality raises with higher index requirements. These oils are used in transmissions, as provide protection elements made of non-ferrous metals, and these most often utilized to construct synchronizers. In contrast, higher API GL-5 is specialized in the toughest working ailments, that is, in rear axles and differentials where you will find extreme pressure gear oils requiring that include very good protection against wear. Oils class API GL-5 meet these requirements, but additive packages reinforcing shielding properties, unfortunately, tend to be ambitious towards ferrous metals and can cause the corrosion. That is why there're used where there are no synchronizers made of non-ferrous metals, but working conditions usually are heavier than in transmissions. It is therefore important to not use oil with API GL-5 pertaining to gearboxes, where oil is required to API GL-4. Sometimes transmissions are identified very unusual requirements. It is always attributable to technical conditions and their cause are often very different. The most common is the use of unusual materials for synchronizers (age. g. Carbon), or additional elements within an oil bath (eg. Intarder). During the final assembly of transmission oil is worth remembering that gear natural skin oils with different quality as well as viscosity do not mix with one another and always use these kinds of oil, which has the expected quality class. This will ensure us long life without the problems for this selection of oil. Another system prone to errors for this selection of a air conditioning fluid. The cooling system is important to the use of such a fluid which can be formed in the pertinent technology. Different types of technology used are conventionally coloured in similar colors. First used technology were the most liquid silicate colored environment friendly or blue. However, these fluids are utilised less and less, because they require replacement every year or so. In addition, the protective layer silicates protection against corrosion in the cooling system reduces the rate of one's transfer from the engine towards the fluid and the fluid towards the radiator. Modern engines are tougher thermal loads and need fluid transport energy faster. Such liquids are liquids which are usually colored red or pink and ensure a faster exchange of one's between the components in the cooling system. With more stable corrosion inhibitors need to be replaced every 5 many years. A very important area of the operation of your vehicle is the dilution regarding concentrates. The concentrate, which water in the ratio of just one: 1 has a freezing point at about -37C. When the proportion regarding 70% concentrate and 30% water you're going to get the lowest freezing point near -60C, but the concentrate using a small presence of h2o will freeze at regarding -18C us! It is also important energy capaAlford in the fluid. Glycol used in the production fluid carries a relatively low energy capability and, unfortunately, does not dissipate energy in the engine. Here we come through water, which by a great power capaAlford dissipate that energy and protect this motor from overheating, while in admixture using a glycol product is small pour point. If we are forced to, eg. To ditional fluid into your cooling system, in this case, the color of the liquid are often very helpful. However, to make absolutely sure use a suitable fluid Always check the vehicle manufacturer's requirements and should pick a liquid that has the required low quality most often described a production or organizational norm one example is. ASTM and SAE.
