Experts teach you to identify oil oil four methods

　　With the increase in car ownership , public demand for refined oil are increasing every day , how can you determine whether to buy their own oil is a regular oil ? Regular oil and how to identify possible security risks of non-standard oil product ? recently, this reporter interviewed experts in the petrochemical oil Guangxi branch .

　　" Harm "

　　Non-formal environmental impact of oil vehicle safety hazards

　　"Currently, in addition to the regular production of oil , there is a non -standard oil products in the domestic market , to reconcile the process of oil ." Oil experts, the so-called non -standard oil, oil refers to the individual projects to meet the national targets oil product quality standards . Most of this oil refinery after a small number of local processing , oil atmospheric distillation obtained . This thick smell of gasoline in general , volatile large , color lighter ; diesel smell is also larger , with the appearance of darker , and high sulfur content , the use of such vehicles against big oil .

　　The blending process oil, refers to a variety of fuels and a variety of conversion processes atmospheric distillation fraction obtained through the above process is refined , although significantly improve quality, but also on the performance of some products can not meet specification requirements oil .

　　Some private oil and gas stations use low-cost purchase inferior quality oil add some oil, then add some additives such as methanol , ethanol and other organic additives , in order to increase gasoline octane index of oil . Although oil blending process makes certain indicators qualified, individual cases may also meet the national standard, but is due to the addition of toxic and hazardous chemicals, plus these private oil depots and service stations do not have instruments to reconcile after gasoline and diesel were detected on the amount of additives added value by experience blending , blending greater harm to humans and the oil out of the vehicles.

　　" Identification "

　　Identify the smell of oil from the appearance, etc.

　　So , how to identify oil bad? Expert Sinopec Guangxi Branch of further information , such as the owners of the car after refueling to find the valve ring, lack of motivation , you should first take into account the grade of gasoline is too low. If the vehicle engine not starting , you should wonder whether the actual quality of the oil caused by unqualified ( impurities, oil impure, adulterated , watered , etc. ) , specific identifiable from the following aspects :

　　1 Appearance and odor . Qualified genuine cars using unleaded petrol should look for the yellow or partial light red, dark red color and found cloudy, foul odor , it may be of poor quality gasoline. Qualified genuine light diesel oil should be transparent amber color , if the color is darker , it may be a problem with oil .

　　2 clogged fuel system. Shoddy gasoline impurities exceeded, when the engine is running, full of poor quality gasoline supply system , pump filter , fuel filter , fuel injectors which have holes or play the role of filtration components can easily be blocked inferior gasoline impurities , resulting in poor fuel , engine function decline .

　　3 coke . Gasoline impurities are generally in the form of gum in the presence of gasoline , even if they passed the filtration device , but also in the intake valve , intake , cylinder siltation , Over the formation of hard coke, gasoline its adsorption effect, will cause the mixture of dilute affect engine operation . More serious is the gum stuck valve on the line and did not return the piston valve collided , causing the engine destroyed.

　　4 oxygen sensors and catalytic converter failure. Gasoline containing impurities can not fully burn , a direct result of poor exhaust , exhaust failure, unstable engine , accelerating weakness, poor overall economic performance, and cost of oil .

　　Given the increase of non- standard oil and cooking oil would cause such a big vehicle and personal harm , oil experts recommend to owners of the best regular gas station , with high-quality oil to extend the life of the vehicle, to avoid any unnecessary personal damage.
