How to Identify Genuine Mobil Oil?

What Causes BMW Engine Oil Leaks?

Below are the reasons and solutions for BMW engine oil leaks: 1. Engine oil cooler leakage. This issue is common across almost all BMW engines, primarily caused by the aging of the engine oil cooler leading to poor sealing and subsequent oil leaks. Upon opening the engine hood, oil leakage at the front of the engine indicates an oil cooler leak. The repair is relatively straightforward—simply replace the engine oil cooler gasket and clean the leaked oil. 2. Valve cover gasket leakage. This type of leak is typically found in the N20 four-cylinder turbocharged engines. The solution usually involves replacing the valve cover with a new, improved version. Other engines rarely experience valve cover leaks, but if they do, it's often due to an aged gasket, which can be resolved by replacing the valve cover gasket. 3. Leaks from other engine components. Examples include oil pan leaks, front/rear crankshaft seal leaks, or leaks caused by aging gaskets in other areas. These leaks are generally less common. When they occur, replacing the corresponding seals or gaskets, or tightening the screws should resolve the issue.

Is it illegal to put advertisements on the rear window of a car?

Pasting advertisements on the rear window of a car is considered a vehicle modification. As long as the advertisement area complies with standards and does not affect safety, it is not illegal. However, if the advertisement area is too large and deemed by traffic police or relevant authorities to affect driving safety, it will be considered illegal. Below are some precautions for vehicle modifications: 1. Choose accessories wisely: Do not blindly pursue the most expensive accessories. Accessories should be selected based on the actual condition of the vehicle. 2. Avoid excessive soundproofing: Do not overly emphasize soundproofing. If the driver cannot hear sounds from the road or the powertrain, they may miss important information about road and vehicle conditions, which can compromise driving safety. 3. Avoid excessive visual enhancements: Do not blindly pursue visual effects. Installing large-diameter exhaust pipes or spoilers for aesthetic purposes may not be meaningful for small-displacement vehicles and could potentially pose significant risks to both the car and the driver.

Is Ethanol Gasoline 92 or 95?

In fact, 92, 95, and 98 are all ethanol gasoline. The different gasoline grades are due to different additives, and ethanol is added later in proportion. When you go to the gas station to refuel, if there is the letter 'e' before the gasoline grade, it means it is ethanol gasoline. Here is more information about ethanol gasoline: 1. Ethanol gasoline is an alternative energy source formed by blending fuel ethanol processed from grains and various plant fibers with regular gasoline in a certain ratio. According to China's national standard, ethanol gasoline is blended with 90% regular gasoline and 10% fuel ethanol, making it a mixture. Adding an appropriate amount of ethanol to gasoline as a vehicle fuel can save petroleum resources, reduce air pollution from vehicle emissions, and also promote agricultural production. 2. The main disadvantages of ethanol gasoline are that users feel it has reduced power compared to regular gasoline, increased fuel consumption, and it is prone to vapor lock and stalling in hot weather. Additionally, since ethanol gasoline separates once it comes into contact with water, it cannot be transported via low-cost pipelines. The storage and transportation cycle of ethanol gasoline is only 4-5 days, which affects the convenience of using ethanol gasoline.

How many days after window tinting can you not roll down the windows?

After applying window tint film to your car, it is recommended to avoid rolling the windows up and down for 5-7 days to prevent damage to the tint film. This is because the tint film needs time to firmly adhere to the window glass. Opening and closing the windows during this period can cause the edges of the newly applied film to peel or the film to shift before it has fully bonded. Here are a few things to keep in mind after tinting: 1. Do not wash the car for 3 days. 2. Avoid wiping the film with cloths containing chemical solvents. 3. Do not place heavy objects on the tint film or attach strong adhesives to it. 4. Prevent hard objects from scratching the film surface.

How to Cancel the Tire Pressure Warning?

There are three methods to eliminate the low tire pressure warning light: 1. Check and confirm whether the tire pressure is normal. If there is an issue, adjust it to the standard pressure, then drive for a few kilometers. Generally, the system will automatically reset at this point. 2. If the tire pressure is confirmed to be normal, visit an auto service shop to inspect the tire pressure sensors and clear the fault code. 3. Locate the settings button on the central console for manual reset, usually by pressing the SET key. The following are the reasons for the tire pressure warning: 1. Decreased tire pressure, mostly due to insufficient tire pressure or a tire leak, requiring inspection. Insufficient pressure requires inflation; a leaking tire needs repair. 2. Inaccurate pressure testing may cause this. You can restart and observe. If the warning persists, it is likely due to reason 1; if the warning stops, there is usually no problem.
