Driving on city roads, everyone hates is traveling slowly, traffic jams, stop and go, just step on the gas immediately and then step on the brake, this driving which driver can not stand ah
In the city, compared to the manual gear, automatic cars, although it looks more comfortable, but the car's fuel consumption has increased a lot. This is an old driver may be well aware of, usually running on the highway fuel consumption in 7-9, traffic jams, fuel consumption at least in the 10-13 or so!
Based on this high fuel consumption, manufacturers have come up with various solutions, of which the “automatic engine start/stop” function is one of the most effective.
Theoretically speaking, when the vehicle is started again (the vehicle is in a warm state), the amount of fuel required to start is only equivalent to the amount of fuel consumed during 7 seconds of idling, so theoretically, if the vehicle is parked for more than 7 seconds, the auto start/stop function will have a fuel-saving effect.
If the idle fuel consumption is at 2L/h (general family car idle fuel consumption is around 2-4L), then idling for 10 seconds consumes 5.5ml of gasoline, while starting once for about 5 seconds consumes about 4.5ml of gasoline!
If you calculate by waiting 60 seconds for each red light, with a vehicle that has an automatic engine start/stop, you save 427ml of gasoline after 15 red lights, which is almost equivalent to a bottle of mineral water ......
Generally speaking, more than 80% of engine wear comes from cold starts, because the oil does not form an oil film quickly and effectively during cold starts, resulting in increased wear between parts.
After normal driving or hot car, the gap between the internal parts of the engine into an oil film, a simple understanding of the parts by the “dry friction” into a “friction oil film” so that greatly reduces the wear and tear. So a good oil is very important for the engine.
In the city's congested road conditions, the car frequently stalled, start, which brings great pressure to the oil, ordinary oil anti-wear, antioxidant and high temperature resistance performance in general, more than the performance of the critical value, the oil's ability to decline, for the engine does not play an effective protection.
For city vehicles often idling, resulting in carbon deposits, oil, this oil also has excellent performance, it has a superb carbon removal function and dispersal of sludge ability, can be a long time to keep the internal engine clean, while in the fuel saving, it also has a good performance.
So, if you drive around town a lot, experience this VW-approved VW50200/50500 lubricant!
