Autumn and winter season engine maintenance: lubricant selection Raiders

Autumn and winter season season, many consumers do not know what lubricant selected for their car, how to election to the most suitable products for the car to be a big confusion in their minds. I specially interviewed Dr. Zhang Shaoming, Lanzhou lubricants research and development center, Dr. Zhang is the most scientific and technological strength of China's oil industry to local brands - Kunlun Lubricant technical experts autumn and winter season, he was taught to the majority of owners the proper selection of lubrication oil "Tips."
Autumn and winter season should be used in small viscosity lubricants
Dr. Zhang said, autumn and winter season selection a suitable lubricant products is very important, and there are a lot of know-how. Autumn and winter season temperatures dropped significantly, auto parts and raw materials, the thermal expansion and contraction effect, the gap between these moving parts with decreasing temperature and a reduced tendency to auto parts are easier to wear in the winter. At the same time, a variety of car lubricants products easily in the case of low temperatures thickens, reduced mobility, and the lubricant temperature in the case of low-temperature heating needs lubricating parts growth, is not easy to start the vehicle. So the season season, lubricating products, lubricating oil or grease should choose small base oil viscosity, low freezing point products such low temperatures in the fall and winter, in order to produce good lubrication.
Multi-grade lubricants used for all seasons
Dr. Zhang said, different engine cooling effect is not the same, so the choice of engine lubricants, manual factory to provide the most basic reference. Furthermore, the temperature condition is also a forced thin to consider in the selection criteria. In general, single-stage engine lubricating oil is limited to a temperature, the price is relatively cheap, and more suitable for areas with small temperature changes. Multi-grade lubricant products, while meeting the the viscosity requirements under the high and low temperatures, all seasons are available.
Dr. Zhang also gave an example: Kunlun Tianwei CD10W-30 is a multi-grade lubricants, including 10W on behalf of low-temperature use range of less than 20 degrees below zero, W refers to different cryogenic temperature range suitable for winter use, there match the different numbers with W, and 30 represent the oil temperature range. It should be said that the -20 ° C to -30 ° C temperature span has been sufficient to meet most of the domestic conditions. Dr. Zhang also use local lubricant brand to consumers, not only can avoid the risk of use of no-name products, with international brands in the same value in use while also saving costs. Dr. Zhang said, the local lubricant brand name already has the strength of science and technology R & D and international brands, the same level, Kunlun Lubricant years of military lubricants R & D and production not only has a strong technical background, but also has two R & D base in Lanzhou and Dalian , leading technology, fully ensure the high-tech products with high quality, but also has the advantage of good local adaptability. Kunlun has viscosity temperature span of the largest multi-grade oil 5W/50, it applies temperature from -30 ℃ to 50 ℃ temperature span reach 80 ℃, powerful and comprehensive.
High-grade product is compatible with low-level products
Dr. Zhang also pointed out that, now more and more of the engine with a new technology, such as turbo cooling technology, if we adopt a high level of quality lubrication products will help to reduce wear and extend engine life. It is worth noting that the high level of lubricating oil can be alternative to the low level of the product, downward compatible. Car manual provisions require the use of CD-grade oil, CE, CF-4, CH-4 diesel engine oil to meet its requirements. For lubricant oil changes, lack of knowledge of consumers, is a more effective common sense when a selected oil.
Dr. Zhang last also cautioned that the oil change, lube oil filters generally need to be replaced, so as to make new replacement the lubricants play better efficacy. And, in general, different brands of lubricant products can not be mixed. The autumn and winter seasonal selection of lubricant products must be scientific and rational, this is a real car maintenance Road.
