BMW X6 rear axle oil requires synthetic gear oil that meets API certification standards GL4 and GL5, with a viscosity of 75w90. Fuel must be clean: High impurity content in fuel can accelerate the wear of the electric fuel pump, reducing its service life. If the fuel is not clean, it can also lead to clogging of the fuel filter and fuel injectors, affecting fuel supply pressure and normal injection volume, thereby reducing the engine's performance. Correct fuel selection: The engine has high requirements for fuel quality and grade, with even higher demands for fuel-injected engines. For cars equipped with catalytic converters and oxygen sensors, only unleaded high-octane gasoline should be used. If leaded gasoline is used, the exhaust catalytic converter will fail after driving more than 400 kilometers, and the oxygen sensor will also malfunction, affecting the normal operation of the engine.

How to Park in an Angled Parking Space?

Park the car on the right side of the parking space along the angled line, adjusting the vehicle to the appropriate position. When the left rearview mirror aligns with the left boundary line of the parking space, adjust the vehicle, turn the steering wheel fully to the right, and continue moving forward. When the body of the car forms a suitable angle with the parking space, and the car body is basically parallel to the parking space, with the left rearview mirror just able to see the left front of the car, stop the vehicle. Observe the left and right rearview mirrors, straighten the wheels, and slowly reverse to make slight adjustments, ensuring the vehicle is aligned with the parking space in a straight line.

What Causes Loud Car Noises?

There are several reasons for loud car noises, including unsuitable engine oil, aging and loose belts, excessively high water temperature, dirty and clogged intake systems, poor sound insulation, etc. Different issues require corresponding inspections and repairs. Unsuitable engine oil: If the oil viscosity is too high and lubrication deteriorates, it may cause loud engine noise. Promptly visit a repair shop to check whether the oil needs replacement. When changing the oil, always choose the type suitable for your car's engine and ensure the oil quality. Aging and loose belts: Check if the belts are loose. Sometimes, loose belts can increase noise in the engine compartment, requiring belt tightening. If the looseness is due to belt aging, replace the belt promptly. Excessively high water temperature: Loud engine noise may result from high water temperature. Check if the temperature gauge is normal and whether there is smoke in the engine compartment. If the water temperature is too high, do not drive the vehicle. Park it in an open area and open the radiator to cool it down. Additionally, ensure the coolant is replaced before winter. Dirty and clogged intake system: If the noise is particularly noticeable when the vehicle idles at high RPM, it may indicate clogging in the throttle body, intake ducts, or fuel injectors, requiring cleaning. Poor sound insulation: If the interior noise is excessive, it suggests poor sound insulation. Check if the vehicle's sealing strips show signs of aging. If so, reseal or add soundproofing materials.

Can Water Enter the Transmission?

Can water enter the transmission? Here are the details: 1. Clean water entry: Try not to drive or run the engine. In this case, the water will settle at the bottom of the gear oil in the transmission. Open the drain screw at the bottom of the transmission to drain all the water and oil, then add new gear oil. 2. Dirty water or water with sediment entry: If clean water enters and the vehicle is driven or the engine is run, the water and oil will emulsify due to high-speed mixing inside the transmission, making it difficult to separate the oil and water. In this case, the transmission must be removed and opened for cleaning. If sediment enters the bearings, especially the input shaft bearing, all components inside the transmission must be disassembled and cleaned.
