Where can a jack lift a car?

There is a protruding long edge along the bottom of the car, and on this long edge, there are several thickened areas designed for jack placement. For household cars, the support points are usually located on the inner side of the side skirts, resembling two fins on either side of the chassis. These are positioned approximately 20 cm behind the front wheels and 20 cm in front of the rear wheels. These fins protrude from the chassis steel plate and can withstand relatively high pressure. Every jack has its designed maximum load capacity. It is crucial not to exceed this limit to prevent insufficient support and potential accidents. When lifting the vehicle, try to remove heavy items from inside the car.

What is the difference between Castrol Magnatec and Edge engine oils?

Castrol Magnatec and Edge engine oils differ in that Edge provides comprehensive engine protection, while Magnatec focuses on cold-start or frequent start-stop engine protection. Below are the detailed explanations: Edge: It offers comprehensive engine protection and is Castrol's top-tier engine oil, comparable to Mobil 1 and Shell Helix Ultra. Edge incorporates a unique liquid titanium formula with adaptive oil film technology, effectively reducing direct metal-to-metal contact and friction losses under various driving conditions. It meets the demanding requirements of high-performance engines operating under extreme temperatures and pressures. Additionally, it helps reduce deposits, keeping the engine clean and enhancing its power performance. Edge has an API rating of SN and comes in four viscosity grades: 0W-40, 5W-40, 5W-30, and 10W-60, catering to different driving conditions. It meets and exceeds the highest oil requirements of numerous engine manufacturers, including those for North American, European, and Japanese high-performance and luxury vehicles. Magnatec: It is a semi-synthetic engine oil with an API rating of SN, suitable for vehicles recommended to use oils meeting API SM/CF, ACEA A3/B3/B4, or earlier specifications, including gasoline, diesel, LPG, and CNG-powered cars.

Can Car Mechanical Keys Be Duplicated?

Car mechanical keys can be duplicated, just like duplicating door keys. However, car keys with built-in chips must be duplicated at a professional 4S shop. Keys duplicated by yourself can be used to open car doors but cannot start the car, because the original key contains an anti-theft chip that requires specialized decoding and encoding equipment for duplication. The functions of a car mechanical key are: 1. Closing windows after turning off the engine; 2. Locating the car in a parking lot; 3. Automatically opening the trunk; 4. Remotely opening windows; 5. Opening the driver's side door. The principle of a car mechanical key is: it consists of a transmitter and a receiver, powered by a battery, emitting low-frequency radio waves from the key. The car antenna then receives the radio wave signal emitted by the key, which is identified by the electronic control unit (ECU) with a specific signal code, and the system executes the actions of locking and unlocking.

How long can a car run without engine oil?

It is not advisable to drive a car without engine oil. The presence of engine oil is crucial for lubricating and cooling the engine. If you force the car to run without oil, the lack of lubrication will cause the engine components to rub against each other, leading to damage. Engine oil serves multiple purposes, including lubrication to reduce friction, aiding in cooling, sealing to prevent leaks, protecting against rust and corrosion, and acting as a shock absorber. Engine oil consists of base oil and additives. The base oil is the primary component of the lubricant, determining its fundamental properties, while additives enhance and compensate for any shortcomings in the base oil, providing additional performance benefits and making them an essential part of the lubricant.

What is the difference between second-generation and fourth-generation car films?

Here is an introduction to the differences between second-generation and fourth-generation car films: 1. Thermal insulation performance: Second-generation films either have high light transmission with poor thermal insulation or good thermal insulation that affects light transmission. Their high reflectivity creates a mirror-like appearance, causing light pollution, and they are prone to oxidation. In contrast, fourth-generation films can largely avoid these drawbacks. 2. Advantages: Second-generation films use new adhesives and thicker layers to improve explosion-proof effects, while fourth-generation films evenly distribute various precious metals on PET substrates through magnetron sputtering technology. They selectively filter visible light while blocking infrared and ultraviolet rays, offering high thermal insulation, high light transmission, high sun protection, low reflectivity, and high toughness, which increases the glass explosion-proof coefficient for safer driving.

What Causes Diesel Fuel to Turn Black?

Diesel fuel turns black due to prolonged storage. Here are some precautions for diesel storage and usage: 1. Prohibited uses: It is strictly forbidden to mix diesel with gasoline for lighting or as fuel for kerosene stoves. 2. Before use: Diesel must undergo sedimentation, filtration, and removal of impurities and moisture before use to ensure the proper functioning of the diesel engine fuel supply system. In winter, it may be necessary to preheat the diesel before use. 3. Mixing: Different grades of diesel within the same classification have basically the same quality indicators except for the freezing point and cold filter plugging point. Therefore, when resources are insufficient, they can be mixed under appropriate temperature conditions.
