Car Parts - how to choose the best?
In every car, even the most reliable, comes in the end time for the replacement of some parts. There is nothing surprising in this. Brake pads wear out during operation, as well as other elements of the mechanism. In this case, it is extremely important to select the appropriate part of the vehicle. Some decide to genuine products, others choose replacements, most important, however, it is quality. Certainly not worth saving for something that can give us security - even if we spend less on pads or brake discs, this is certainly more important to our health, which often depends on the efficiency of the car. The best solution is to consult an experienced mechanic who can help choose the best in our situation auto parts.
History of engine oil
On September 6, 1866 American John Ellis founded the Continuous Oil Refining Company (Later to become Valvoline). While studying the possible healing powers of crude oil, Dr. Ellis was disappointed to find no real medicinal value, but was intrigued by its potential lubricating properties. He eventually abandoned the medical practice to devote his time to the development of an all-petroleum, high viscosity lubricant for steam engines ? then using inefficient combinations of petroleum and animal and vegetable fats. He made his breakthrough when he developed an oil that worked effectively in high temperatures. This meant no more gummed valves, corroded cylinders or leaking seals. In 1873 Ellis officially renamed the company to Valvoline after the steam engine valves the product lubricated.
Motor oil, engine oil, or engine lubricant is any of various substances (comprising oil enhanced with additives, for example, in many cases, extreme pressure additives) that are used for lubrication of internal combustion engines. The main function of motor oil is to reduce wear on moving parts; it also cleans, inhibits corrosion, improves sealing, and cools the engine by carrying heat away from moving parts.1
Motor oils are derived from petroleum-based and non-petroleum-synthesized chemical compounds. Motor oils today are mainly blended by using base oils composed of hydrocarbons, polyalphaolefins (PAO), and polyinternal olefins2 (PIO), thus organic compounds consisting entirely of carbon and hydrogen. The base oils of some high-performance motor oils contain up to 20% by weight of esters.3
