The maintenance and maintenance of trucks has always been a topic of concern to transportation companies and drivers. It is well-known that good condition is a solid foundation for business growth. When the truck is in a new car, the engine is in a running-in phase, and the quality of running-in will have a significant impact on engine life, vehicle safety, and economy. Therefore, the maintenance work must be started from the start of the new car.
Many drivers think that vehicle maintenance is a professional job and often do not know where to start. In fact, as long as we pay more attention in two areas, it is not difficult to maintain a good state of the new car.
First, drivers must cultivate good driving habits. Usually, the running-in period of the new car is about 3,000 kilometers. During this process, it should be kept as even as possible to avoid accelerator pedals or brakes. In addition, try to run at an economical speed (eg 80 km/h) and avoid high-speed driving. .
On the other hand, choosing a high-quality engine oil can provide better protection to the engine. In general, the engine oil mainly plays a role in lubricating, cleaning, cooling, sealing, and grinding. High-quality engine oil has stable viscosity, good cleanliness, and strong rust-proof and corrosion-proof ability, which can effectively reduce the wear of impurities on the engine. At the same time, it has better heat dissipation and can effectively reduce fuel consumption.
In general, the use of high-quality engine oil does not cause abnormal noise and the service life can be extended. In addition, in general, the new car should change its oil almost every three months or 10,000 kilometers. However, with good oil, this cycle can be appropriately extended.
Choosing a motor oil with superior performance and affordable price is a technical task. It is recommended that drivers choose the brand oil with guaranteed quality as much as possible. The Meifu Black Overlord with more than 80 years of history is a brand that many drivers are familiar with. Recently, after doing a brand new upgrade, the performance is even better. The driver who is about to change oil may wish to try.

Cold drawn steel bar is produced by hot rolled steel bar or wire rod to get smooth surface, more precision size, higher mechanical properties, which improves machining characteristics. It can also get various sections and sizes. So cold drawn steel bar is a better choice for machining users.
According to different steel grade, the production line is usually different. The Basic production line is as below:
For high carbon steel or alloy steel bars, to avoid the cracks in inner or surface, the bars are usually required to be annealed before cold drawing.
To get different mechanical properties or hardness depending on final usage, the cold drawn bars will also be heat treated such as annealed, normalized or quenched and tempered(Q&T).
For CNC machines usage, to get much more precision sizes or much more better surface roughness for chrome plating, the cold drawn steel bars can also be centerless ground or polished.
We have more advantages on producing cold drawn steel bars:
1) Big stocks of hot rolled round bars or wire rods as raw materials
2) Wide range of cold drawn steel bar sizes: from 10mm to 150mm
3) Different cold drawing medias powder or oil to get different surface
4) Straightening machines to get better straightness up to 0.5mm/m
5) Grinding and polishing machines to get better roughness upto 0.4um
6) Heat treating furnaces to adjust the mechanical properties
7) Full sets of testing equipment to test the sizes, mechanical properties and microstructure.
8) Multiple packages to avoid broken packages and anti-rusty
