1, the oil consumption is high, slow speed is what reason?

There are many factors resulting in high oil consumption, such as driving habits (emergency refueling, slam the brakes, coasting, speed and gear does not match), the tire pressure is too low, the addition of inferior oil, ignition system fault and the fault of electronic control system,the fault will increase vehicle fuel consumption. Secondly, if the vehicle is not timelymaintenance, such as not timely replacement air filter, gas filter, spark plug and clutch plates etc. these components, can also lead to increased fuel consumption.

Another is the product of fault carbon and electric control system, such as the solar term door body, idle valve and injector carbon, oxygen sensor, air flow meter and a water temperature sensor signal misalignment and so on, these will affect the vehicle fuel consumption, high oil consumption needs to conduct a comprehensive inspection. For you this car, the oil consumption is high, check the focus of each sensor signal is normal, check whether the parts of carbon deposition seriously, check whether there is a problem to add oil etc..

2, car battery electricity will not lead to loss power shortage?

No, just means no car, but if the battery internal short circuit, it is possible to happen.

3, the engine abnormal indication light do?

Engine fault light. Otherwise the engine does exist the problem of fault. Need to shopinspection and maintenance. Or is the program problems. To store re computer programming.

4, how to check whether the brake fluid leaks?

Let the engine idling, and the transmission shaft in a "neutral" position, the brake pedal, pedalforce and remain unchanged. If in force under the condition of invariable, pedal slowlywhereabouts, then hydraulic braking system may have leaks, the following visual inspection to confirm whether there is leakage.

1 check the liquid storage device of braking general pump the liquid level in the normalposition, the friction lining wear will lead to liquid level decreased slightly. If the reservoir levelreduce the anomaly, will cause the brake warning lamp lit, it indicates that there may beinternal or external leakage of hydraulic system.

2 check the brake pipe and brake hose connections for leaks, if there is leakage, check thefastener torque, or replace the oil pipe or hose.

3 check the connection brake element is damaged, if necessary to reinstall or replace connection brake components. Check the calipers and wheel cylinder protection cover isleakage, such as leakage, when necessary to reinstall or replacement of these components.
