There are many owners do not know to replace the steering wheel oil, has not been to pay attention to, until the steering wheel oil leakage or heavy hand, it is too late. 

General repair method is to change, insurance, change the brand new, but very expensive; save for regeneration, but by old products to renovate is not very safe; the most economical way is to buy tank oil is not enough. 

In fact, the steering machine and hydraulic pump is also composed of some parts and oil seal gasket, will leak oil, almost all oil seal problems. 

Most people are not easy to overlook the power oil replacement, even some maintenance factory will be ignored, some need to change with the automatic transmission oil (ATF) when the power to use oil, although the power oil and automatic gearbox oil belong to hydraulic oil, but oil is not the same, power oil oil, automatic transmission oil is a slippery friction oil, a more astringent. But the most important thing is that no matter what the oil has a certain life, unlike oil, oil power since the discharge of oil at a high temperature operation, so a long life of about three years and fifty thousand kilometers around the city, but often often hit the steering wheel or parking vehicles may also advance some replacement. If you ignore the replacement, deterioration of the power, oil will lose the role of the protection of oil seals, so that oil seals, oil pipes early hardening, resulting in oil spills. 

If your driving habit will drive the wheel to the end, then the system will always maintain a high pressure, the channel closed close, resulting in increased pressure. At this time, the booster pump because the oil can not flow quickly, causing the pump shaft rotation resistance, and through the rotating disk and rotating belt will add this resistance to the engine. If the engine is idle at this time, it is easy to cause idle instability or flameout. In general, the hydraulic power steering pump has a pressure sensor, it will bring pressure to the computer, the computer will increase the amount of fuel injection, improve the speed, prevent flameout, but the amount is limited, if the dead time is too long, the machine will eventually because of low speed and flameout. If artificially increase the throttle, maintain the direction of state killing time is too long, will cause the power system pressure is too high, resulting in power system short life or early damage. 

Since the direction of power is not used to lubricate the oil, but only to provide hydraulic power, so the direction of the oil requirements are generally not high.
