Nissan QR25 engine uses 5W/40 synthetic oil. The role of engine oil: As a lubricant for the engine, engine oil continuously flows into various transmission components during engine operation, forming an oil film between friction surfaces, thereby reducing friction resistance, lowering power consumption, and minimizing component wear. Precautions for using engine oil: The selection of engine oil should be based on the engine's requirements. It is unnecessary to use overly advanced oil in engines with lower requirements, nor should lower-grade oil be used in engines with higher requirements. Therefore, it is advisable to choose multi-grade oil, which offers advantages such as economy, long service life, and high efficiency, providing better protection for the engine. Due to the characteristics of multi-grade oil, phenomena such as premature darkening and lower oil pressure compared to conventional oil may occur during use, which are normal.

How many kilometers does the BMW 3 Series fuel filter need to be replaced?

The replacement interval for the BMW 3 Series fuel filter is generally around 10,000 kilometers. The specific replacement time can be referred to the instructions in the vehicle's user manual. Typically, the fuel filter is replaced during major maintenance of the car, along with the air filter and oil filter. The gasoline filter usually has only one stage, installed between the fuel tank and fuel pump or between the fuel pump and carburetor. Since the diesel engine supply system has three precision components that require higher cleanliness of diesel fuel, and diesel contains higher levels of gum, diesel filters generally have two or more stages to improve filtration efficiency. They are divided into diesel coarse and fine filters, also known as water separators and diesel fine filters, installed between the diesel tank and fuel transfer pump, and between the fuel transfer pump and injection pump, respectively. Some diesel engines are also equipped with sediment bowls to settle water and impurities in the diesel fuel.

What to Do If You Lose Your Teana Car Key?

If you lose your Nissan Teana smart key, you can go to a 4S shop or a professional car key shop to have a new one made. The ignition lock cylinder's reading coil can read the chip in the key; each chip has fixed digital information. Here are some relevant details: 1. Spare Key: After losing the key, the spare key can still be used normally. 2. Getting a New Key: The 4S shop needs to match the new key with a "code" from the original car. Once the matching is completed, the new key can be activated, and the lost key will become invalid. Even if someone finds the old key, they can only open the car door mechanically but cannot start the vehicle.

Do I need to add water when using windshield washer fluid?

Windshield washer fluid does not require adding water when in use. Automotive windshield washer fluid comes in two types: concentrated and non-concentrated. The commonly used non-concentrated type is usually packaged in large bottles and is pre-mixed, requiring no dilution with water. The less commonly used concentrated type needs to be diluted with water and is typically packaged in small bottles, often referred to as wiper fluid concentrate, etc. The method of use is to first pour the wiper fluid concentrate into the car's windshield washer fluid reservoir, then add an appropriate amount of purified water for dilution. Windshield washer fluid is the common name for automotive windshield cleaning fluid and is a consumable in car use. It is composed of water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants, and has functions such as cleaning, antifreeze, antifog, anticorrosion, antistatic, and lubrication.
