Gasoline also known as petrol outside North America, is a transparent, petroleum-derived liquid that is used primarily as a fuel in internal combustion engines. It consists mostly of organic compounds obtained by the fractional distillation of petroleum, enhanced with a variety of additives.
On average, a 42-gallon barrel of crude oil (159 L) yields about 19 US gallons (72 L) of gasoline when processed in an oil refinery, though this can and does vary based on the crude oil source's assay.
The characteristic of a particular gasoline blend to resist igniting too early (which causes knocking and reduces efficiency in reciprocating engines) is measured by its octane rating. Gasoline is produced in several grades of octane rating. Tetraethyllead and other lead compounds are no longer used in most areas to regulate and increase octane-rating, but many other additives are put into gasoline to improve its chemical stability, control corrosiveness and provide fuel system 'cleaning,' and determine performance characteristics under intended use. Sometimes, gasoline also contains ethanol as an alternative fuel, for economic or environmental reasons.
Location garage - how to choose?
Nowadays, more and more people are choosing to buy their own car. And there is nothing surprising in this - after all, the car provides independence and is extremely convenient means of transport. Each vehicle requires service from time to time, or repair certain faults or replacement of wearing parts in everyday life. This makes the mechanics willing to assume workshops. But in order to achieve financial success, it is well to consider the location of such a plant. If the area is a lot of competition, you better look for another place. It should provide good access and be well marked in such a way to customers had no trouble finding it.
Used car parts - worth it?
In many cases, the maintenance of vehicles made by a real expert in the field of electronics or auto mechanics is essential. Many people, however, will perform the repair at his own expense, using commonly available knowledge in this area. In this case, the preferred embodiment may be used to purchase a car parts. Admittedly, car parts, which have already been used can be a bit tired, but they tend to be several times cheaper than new equipment. No wonder that the automotive aftermarket is booming, and the exchange between the owners of auto parts may be getting more efficient, for example, thanks to the Internet.
