With the national six models on the line, more car manufacturers are low viscosity oil as the vehicle's factory viscosity, that is, 5W30, 5W20, 0W20, for the Japanese Toyota, Honda, Nissan, Mazda, Mitsubishi, South Korea's Kia Hyundai, the U.S. General Motors, Ford, Dodge, JEEP, Land Rover, etc., must be specified 0W20. If the factory viscosity is 0W20 oil, or with a higher viscosity 40 oil, the life of the car will be greatly shortened, fuel consumption will rise by more than 4%, the dry sound will also become larger, 0W20 whether from the heat dissipation, or fluidity is far better than 40 viscosity oil. New Mazda Atlas, Enclave, gasoline Land Rover, Jeep, Ford 1.5T, 1.2T, General 1.4T preferred 0W20, followed by 5W20, run to a certain amount of wear and tear after the selection of 5W30!
Today's rapid development of science and technology, the engine manufacturing process is more and more sophisticated, the new car factory recommended oil viscosity 5W20, 0W20 this viscosity level of oil, viscosity is lower, faster lubrication and protection of friction parts. Viscosity is low, so the frictional resistance of the engine to do work becomes smaller, saving fuel, oil flow rate is fast, fast heat dissipation, the engine condition will remain in the best state, to extend the life of the engine. Viscosity error on the engine, viscosity with too high, such as the original factory recommended viscosity should be used 0W-20, but the use of 5W-30 or 10w-40 or even higher viscosity oil, will cause the vehicle's fuel consumption will increase, the vehicle noise will also become larger, the engine running resistance will become larger, the oil film will be intermittent, the engine will increase wear, this is why the same engine in the domestic average life even one-third of the life of foreign countries. This is why the average life of the same engine in the country and even one-third of the life of foreign countries are not one of the reasons. When the vehicle is used after a certain mileage, generally 15-20 million kilometers or more, the engine wear will increase, the piston rings and the gap between the cylinder will increase, if you find a slight oil burning can increase the viscosity of the oil to reduce oil burning, but this is not a complete solution to the problem of oil burning. At present, many repair shops still hold the old backward knowledge of lubricants, like to use the concentration of high oil, to 5W-40 and 10W-40 oil is mainly given the reason is mainly worried about the condition of the car will burn oil, thus causing customer complaints, but in fact, 5W-40 and 10W-40 oil for most of the vehicle is the concentration of high oil, is not the most suitable for their own vehicles engine oil! ! Choose the right oil for you, Master Bong will match the most suitable oil viscosity for you.
