What Is Engine Oil

The most favorable job gasoline engine oil quality classification symbol job classification standard API engine motor oil Effectiveness ASTM standard petrol engine of SA - means the petrol engine operation under favorable circumstances, those who do not use oil containing any added use it. Such is no specific test standard operation of the engine. Add free use of motor oil. But necessary, to add liquidity point depressants have used and defoamers. SB lowest petrol engine of job safety requirements - petrol engine means at relatively favorable job situation, the oil there is no need to increase the minimum requirements of the additives, can achieve the best maintenance claimant. Under such standard operating oil began with the 1939, 1930 - The main requirement for the anti-wear, anti-oxidation, and corrosion resistance of the bearing. It contains antioxidants and anti-wear agents of oil. SC 1964 gasoline engine warranty work between use of a 1964 to 1967 cars and trucks manufactured between the petrol engine, the vehicle manufacturers to ensure that under the terms of the operator. For such operations by the motor oil should be able to resist the gasoline engine at high and low temperatures the contamination wear and corrosion properties. 1644-1967 in line with the requirements of the manufacturer of the depot quality motor oil. Mainly for small passenger cars with engine lubrication oil should contain an anti-corrosion and anti-contamination of additives hypothermia. SD 1968 years to ensure maintenance of the operation of gasoline engine gasoline engine one finger between 1968 to 1970 cars and trucks of the factory, according to the vehicle manufacturer permits the maintenance and use of the operator. 1971 Most vehicles are also applicable to this case. By using the oil for such operations should be able to resist the use of the car petrol engine and high-temperature and low temperature under 樍 dirt, wear, and corrosion properties. On oil quality is concerned, this characteristic should be much higher than the above-mentioned oil SC's job better. It can replace SC purposes. 1968-1971 in line with the requirements of the vehicle manufacturer married quality motor oil. Mainly for small passenger cars with engine lubrication oil should contain an anti-corrosion and anti-contamination of additives hypothermia. SE 1971 ~ 1974 years, the gasoline engine to ensure the maintenance of jobs from 1971 to 1974 refers to the factory car and truck gasoline engine, the vehicle manufacturers in ensuring the maintenance and use of the operator. For such operations by the motor oil should be more resistant to the oxidation resistance of the gasoline engine, the characteristics of the contamination under the high temperature and low temperature, wear and galling of, and more above the oil SC or SD jobs better. So the oil can be substituted SC or SD two oils. 1972 in line with the vehicle manufacturer's motor oil quality requirements. Mainly for small passenger cars, truck gasoline engine lubrication purposes. Oil contains high-temperature oxidation, low temperature resistance contamination and anti-corrosion additives. SF 1980 after he made petrol engine manufacturers and some bus repair work truck gasoline engine jobs typical in 1980 under the engine manufacturer's recommended procedures after a repair job. SE grade fuel oil this school has better and better the oxidation stability of the anti-abrasion resistance, this needle rust and corrosion fouling engine has a great guarantee. 1980 in line with automobile manufacturers and engine repair job requirements that has anti-oxidation, anti-wear, anti-friction, saving gasoline and other features. SG for 1989 after the lubrication of small passenger cars, station wagons, minivans and other gasoline engine of. Deposits within the engine control, the oxidation resistance and reduce engine wear, the grade is better than before. SF and replaces the previous rating of the oil. 1989 to meet the requirements of automotive manufacturers and suppliers of engine repair work. Acceptance criteria SH 1993 onwards, API gasoline engine of the test, the first multi-test, with its mean value within the limits of its compliance with the requirements, the only nuclear to SH level of charter. 1993 in line with automobile manufacturers and lead to take the revised version essay requirement. The API Service Grade engine oil of API Classification API engine quality job classification standard SA for older petrol engines, no special performance requirements. Special recommendation applies only to the manufacturer of the engine. Pure mineral oil does not contain any oil additives of. SB for older petrol engines, no special performance requirements. Special recommendation applies only to the manufacturer of the engine. With anti-wear, anti-oxidation, but no pure functional additives. SC for 1967 and the factory before the old petrol engine, with inhibition at high temperatures and low fouling characteristics of the gasoline engine, wear and corrosion. SD for 1967 and the factory before the old petrol engine, with inhibition at high temperatures and low fouling characteristics of the gasoline engine, wear and corrosion. On oil in terms of quality, performance is better than the above-mentioned SC grades, it can replace SC purposes. SE for 1979 and the factory before the old gasoline engines, gasoline engines to better suppress the oxidation, the characteristics of fouling, wear and corrosion at high and low temperatures. SE can replace SCSD two oil level. SF for 1988 and the factory before the old petrol engine, SF SE grade level compared with antioxidant and anti-wear better. SF stage may replace SC, SD, SE oil use levels. SG for 1993 and the factory before the old petrol engine improved diesel and sludge control, can replace SF and grade of oil before. SH for 1996 and the factory before the petrol engine, using the SG and the value of the test requirements, CMA (Chemical Manufacturers Association) to meet stringent guidelines adopted by the specifications. SJ for 2001 and the factory before the petrol engine, since October 15, 1996 came into force, and its specifications SH lies beyond the low temperature fluidity, volatility, filtration, anti-foam and high-temperature thermal oxidation stability of more stringent requirements, according to another characteristic of the oil in the phosphorus content from 0.12 percent down to 0.10 percent, in order to reduce the poisoning of the catalyst, the oil can replace all of the specifications of its former use API gasoline engine oil specification. SL suitable for all being used in car engines, SL class on July 1, 2001 began to import, and provide better control of high temperature deposits and saving fuel consumption, some SL-Class also standard certification through the International Committee of the lubricating oil specification standards. This series on July 1, 2001 came, applicable to all types of existing petrol engine, SL oil fouling control with excellent high temperature and low fuel consumption. Part of the oil at the same time meet the latest ILSAC specification or the energy-saving qualities. SM together all being used in car engines, antioxidant capacity requirements than twice the SL level increase, reducing the production of coke, camshaft wear resistance capability requirements, compared with 25% SL level is raised. American Petroleum Institute America Petroleum Institute - API American Petroleum Institute API is an unofficial non-profit organization, dedicated to the oil drilling industry, the petrochemical industry and services, the American Petroleum Institute has established a standard that provides a set of quality and product certification system, so the opportunity to API manufacturers can mark this logo on their products, to show the products meet recognized quality and API requirements. To obtain certification, the manufacturer must establish the quality management system API-Q1.
