【 Master Bang online 】 City stop-and-go, what oil should the car add?

Driving on urban roads, we hate the most is slow driving, traffic jams, stop-and-go, just stepped on the accelerator immediately to step on the brake, this way of driving which driver can not stand ah!

Automatic start-stop

In the city, compared with manual transmission, automatic transmission cars look more comfortable, but the car's fuel consumption has increased a lot. This old driver may have a deep understanding, generally running high speed fuel consumption in 7-9, if the traffic jam fuel consumption at least in 10-13 or so!

Based on this high fuel consumption, manufacturers have also come up with a variety of solutions, of which the "automatic engine start and stop" function is one of the most effective methods.

In theory, when the vehicle starts again (the vehicle is in a hot car state), the fuel consumption required for starting is only equivalent to the fuel consumption of 7 seconds of idle speed, so in theory, if the car stops for more than 7 seconds, the automatic start-stop function has fuel saving effect.

If the idle fuel consumption is 2L/h (the idle fuel consumption of the general family car is about 2-4L), the idle speed will consume 5.5ml of gasoline for 10 seconds, and the time to start once is about 5 seconds to consume 4.5ml of gasoline!

If you wait 60 seconds at each red light, with a vehicle with an automatic engine start and stop, you will save 427ml of gasoline after 15 red lights, almost equivalent to a bottle of mineral water...

Oil protection

Most owners know that frequent starting will cause additional engine wear, and a good oil can solve this problem.

In general, more than 80% of the wear of the engine comes from cold starting, because the oil cannot form an oil film quickly and effectively during cold starting, resulting in increased wear between parts.

After normal driving or hot car, the gap between the internal parts of the engine becomes an oil film, a simple understanding is that the parts from "dry friction" into "friction oil film", which greatly reduces wear. So a good oil is very important for the engine.

In the congested road conditions in the city, the car frequently flout, start, which brings huge pressure to the oil, ordinary oil wear resistance, oxidation resistance and high temperature performance in general, after exceeding the critical value of performance, the ability of the oil to decline, for the engine can not be effective protection.

Especially for vehicles equipped with automatic engine start and stop, frequent engine start and stop have high requirements for oil, which not only needs good wear resistance but also must have high temperature resistance.

A good bucket of oil

Not all oils can do this, but the VW50200/50500 certified by Volkswagen is a good choice.

This engine oil is designed for hot, humid, and often stop-and-go urban road conditions. In the oil film strength, the high temperature and high shear viscosity value is greater than 3.5, and the oil film can be quickly formed at the start, and the maximum resistance to wear and protection of the engine.

For urban vehicles often idling, resulting in a lot of carbon deposits, oil, this oil also has excellent performance, it has a strong removal of carbon deposits and dispersion of sludge ability, can keep the engine internal clean, while saving fuel, it also has a good performance.

So, if you often drive in the city, you may wish to experience this Volkswagen certified VW50200/50500 lubricant!
