High speed slow, what reason be?

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 timely maintenance, such as not timely replacement air filter, gas filter, spark plug and clutch plates etc. these components, can also lead toincreased fuel consumption.

Another is the product of fault carbon and electric control system, such as the throttle body and 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's fuel consumption, high oil consumption needs to conduct a comprehensive inspection. Foryou 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..

Car battery electricity will not lead to loss of insufficient power?

No, just cause can't start the car, but if the battery internal short circuit, it is possible to happen.

The engine abnormal indication light do?

Engine fault light. Otherwise the engine does exist problem, need to shop inspection and maintenance; or program problems, to the shop to re computer programming.

How to check the brake fluid leaks?

Let the engine idling, and the transmission shaft in a "neutral" position, the brake pedal, pedal force and remain unchanged. If in force under the condition of invariable,pedal slowly whereabouts, 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 thenormal position, the friction lining wear will lead to liquid level decreased slightly. If the reservoir level reduce the anomaly, will cause the brake warning lamp lit, it indicates that there may be internal or external leakage of hydraulic system.

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

3 check the connection brake element is damaged, replace if necessary to reinstall orconnected with the brake components. Check the calipers and wheel cylinderprotection cover is leakage, such as leakage, when necessary to reinstall orreplacement of these components.
