(2) Multi-stage oils should be selected as much as possible. Multi-stage oils have good protection effects on the engine due to its saving, long life, and high efficiency. Based on the characteristics of multi-grade oils, premature blackening may occur during use, and the oil pressure is smaller than ordinary oil. (3) The quality of some domestically-made brand-name oils is quite good, and the price is lower than that of imported similar products. It can be used with confidence, and there is no need to blindly pursue “dollar oilâ€. (4) If the engine is in good condition and the seasonal temperature is low, the less viscous oil should be used as far as possible so that the oil path can be opened. For example, in high temperature seasons or severe engine wear conditions, the use of high-viscosity motor oil is beneficial to oil film formation and engine wear. Architectural Tension Bar For Construction High Strength Steel Tie Rod are steel structural members made of carbon structural steel and alloy steel, processed by machining, heat treatment and surface anti-corrosion treatment, supplemented by adjusting sleeves, lock and joints etc. The steel tie rod are important components of steel structures for construction of giant, large span buildings and ship docks. They are mainly used for prestressed parts and large span buildings in construction projects. While the strength of the product is improved, but the plasticity index is not reduced, which satisfies the principle of using the same amount of strength in the architectural design. The tie rods, tie bars, tension rods and tension bars steel grades are specified as grade 460, grade 520, grade 550, grade 650.

(1) The choice of engine oil should be based on the requirements of the engine. It is not necessary to use too high-grade engine oil on lower-demand engines, or to use lower-grade engine oil on more demanding engines.
Optional oil note four elements
The maintenance experts of the automobile industry believe that under normal circumstances, the following four elements should be taken into consideration when selecting motor oil:
