the basic job of the engine oil is to prevent all metal surfaces in the car engine from laboring together and thus tearing them apart due to friction.our company is professional hydraulic motor,piston motor,hydraulic winch,gearbox,pg电子下载-pg电子游戏 supplier providing customers from domestic zhongyiyepk and overseas the best and reliable hydraulic products.welcome to visit our website. the engine oil should also be potent enough to resist all by-products of combustion.
all chemicals and acids collected in the engine are cleared by the engine oil and it also ensures all parts of the engine are covered in oil. engine oil also reduces oxidation happening at high temperatures. all these tasks are performed under an extremely high temperature and pressure level. difference in motor oil types is based on the way it is obtained or on the conditions it is best suited for, as explained below.
basic motor oil types
conventional motor oil
this is the least expensive of all three motor oil types. the conventional motor oil is mainly a byproduct produced during the crude oil refinement process. since this oil does not have a complicated make-up process, it is liable to faster deterioration, when subjected to extreme heat. the conventional motor oil emits higher amounts of sulfur and other pollutants as well.
synthetic motor oil
this is the most expensive of all three types of motor oils. synthetic motor oil costs more as it is expensive to produce. it is developed from polyalphaolefins, a chemical compound. the total structure of synthetic oils is unique and hence it is considered to be cleaner and stable than conventional oil. also, this oil can maintain its flow under almost all conditions regardless of the heat and pressure. read more on best synthetic motor oil.
this oil combines properties of both synthetic as well as conventional motor oils. the idea behind synthetic blend oil is to combine the price of conventional oil with benefits of synthetic oil. synthetic blend oils are a more refined version of conventional oils, which burn better and also stay stable at high temperatures.
different motor oil types according to gradation
motor oils have been graded according to their viscosity properties by the society of automotive engineers. the numerical code contains numbers followed by the letter w, like 0w, 15w and 25w. viscosity is gauged by measuring the time taken by the oil to travel through a standard opening at normal temperatures. the more time the oil takes to travel, the higher is its viscosity and consequently a higher grade. depending on the grade, the various motor oil types are explained below.
how to choose a supplier?if your quantity is small, you can go to a local wholesaler, but if you want to order more, go directly to a factory will be more cost-effective. ningbo zhongyi hydraulic motor co., ltd will can provide superior-quality pg电子下载-pg电子游戏, piston motor, hydraulic winch,axial piston motor,pg电子下载-pg电子游戏 products and satisfactory service.
