oil for Ariel antique car is not just spending
Beautiful cars many years ago still able to impress not only lovers of the automotive industry, but also people who do not fully interested in cars. Attention is drawn primarily body, which no longer stumbles on Polish streets. Contrary to appearances, have a historic car can bring many benefits, including those financial statements. The best example is certainly possible to rent such a car in various celebrations, so eg. For weddings. However, it was possible to make money in this way, it is necessary to bring the car to the historic state of almost perfect, where the body will admire a beautiful line and the engine will operate flawlessly.
Properties of engine oils
Most motor oils are made from a heavier, thicker petroleum hydrocarbon base stock derived from crude oil, with additives to improve certain properties. The bulk of a typical motor oil consists of hydrocarbons with between 18 and 34 carbon atoms per molecule.7 One of the most important properties of motor oil in maintaining a lubricating film between moving parts is its viscosity. The viscosity of a liquid can be thought of as its "thickness" or a measure of its resistance to flow. The viscosity must be high enough to maintain a lubricating film, but low enough that the oil can flow around the engine parts under all conditions. The viscosity index is a measure of how much the oil's viscosity changes as temperature changes. A higher viscosity index indicates the viscosity changes less with temperature than a lower viscosity index.
Motor oil must be able to flow adequately at the lowest temperature it is expected to experience in order to minimize metal to metal contact between moving parts upon starting up the engine. The pour point defined first this property of motor oil, as defined by ASTM D97 as "... an index of the lowest temperature of its utility ..." for a given application,8 but the "cold cranking simulator" (CCS, see ASTM D5293-08) and "Mini-Rotary Viscometer" (MRV, see ASTM D3829-02(2007), ASTM D4684-08) are today the properties required in motor oil specs and define the SAE classifications.
Oil is largely composed of hydrocarbons which can burn if ignited. Still another important property of motor oil is its flash point, the lowest temperature at which the oil gives off vapors which can ignite. It is dangerous for the oil in a motor to ignite and burn, so a high flash point is desirable. At a petroleum refinery, fractional distillation separates a motor oil fraction from other crude oil fractions, removing the more volatile components, and therefore increasing the oil's flash point (reducing its tendency to burn).
Another manipulated property of motor oil is its Total base number (TBN), which is a measurement of the reserve alkalinity of an oil, meaning its ability to neutralize acids. The resulting quantity is determined as mg KOH/ (gram of lubricant). Analogously, Total acid number (TAN) is the measure of a lubricant's acidity. Other tests include zinc, phosphorus, or sulfur content, and testing for excessive foaming.
The NOACK volatility (ASTM D-5800) Test determines the physical evaporation loss of lubricants in high temperature service. A maximum of 14% evaporation loss is allowable to meet API SL and ILSAC GF-3 specifications. Some automotive OEM oil specifications require lower than 10%.

consequences of saving oil brake
The reasons for the small car breakdown can be really mundane. Inexperienced drivers do not even realize this, how can they lead to a failure in his car. Meanwhile, the consequence of the use of motor oil of poor quality may be overheating or cooling of the engine, by which it will begin to function worse and worse, and eventually refuse to obey the driver. There should also save on oil brake, because its deficiencies in the car can lead to the fact that the brakes will react with a delay, and this situation is particularly dangerous for the driver and other road users. On the other hand, perhaps the largest number of drivers are aware of what may be the consequences of using old car tires.
