问：汽车开始振动很多

你好呀。实际上，LX470确实高级汽油. When a lower octane is used such as 87 unleaded than there is a possibility for the engine to knock. In most cases, the vehicle’s computer will adjust to the lower octane rated gas and the knocking will cease. If this does not occur, then there may be other problems. A qualified technician, such as one from YourMechanic, will be able to assist with诊断汽车的振动问题并让您知道需要修理什么。
