How to Deal with Minor Scratches on a Car?

Here are the methods for handling minor scratches on a car: 1. Use a touch-up pen for small scratches. If the rust is not severe, first gently sand the rust spots with very fine water sandpaper dipped in water, but avoid sanding randomly—always sand in straight lines in the same direction. After completely cleaning the area, apply a layer of primer. 2. Apply toothpaste as a temporary rust prevention measure. When you notice new small scratches on the car body, gently apply toothpaste in a circular motion over the scratch. 3. The best way to repair a scratch is to fill the damaged area with a coating agent that matches the car body. The coating agent can be applied once, twice, or three times—the more applications, the cleaner the finish. 4. For very shallow scratches that only affect the surface paint, immediately treat them with a compound. Wipe in straight lines. Once the scratch disappears, use a finer compound to wipe again, then apply wax. 5. For deeper scratches, the key is to check if the metal surface is exposed. If the metal is not visible, rust will not form, and you can carefully apply touch-up paint with the tip of a brush. Wait for the paint to dry completely.

What is the 0-100 km/h acceleration time of the BMW X3 M?

The 0-100 km/h acceleration time of the BMW X3 M varies depending on the model: 1. The standard version accelerates from 0-100 km/h in 4.3 seconds; 2. The Competition version achieves this in 4.2 seconds. The 0-100 km/h acceleration time refers to the duration it takes for a vehicle to accelerate from standstill to 100 km/h, which is a direct reflection of a car's power performance. Taking the 2019 BMW X3 M as an example, it is classified as a midsize SUV with the following dimensions: length 4728mm, width 1897mm, height 1688mm, wheelbase 1864mm, and a fuel tank capacity of 65 liters. The 2019 BMW X3 M is equipped with a 3.0T twin-turbocharged engine producing a maximum horsepower of 480 PS, peak power of 353 kW, and maximum torque of 600 N·m, paired with an 8-speed automatic transmission.

Should the Lincoln Nautilus use 95 or 92 octane gasoline?

The Lincoln Nautilus can use 92 octane gasoline. This octane rating is recommended in the vehicle's official owner's manual. In addition to checking the appropriate gasoline octane in the owner's manual, the recommended octane rating is also indicated on the fuel tank cap. Generally, the required octane can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95 octane. If the compression ratio is even higher, 98 octane gasoline is recommended. However, with the use of new technologies, the compression ratio alone cannot determine the required octane rating. High compression ratio engines can still be tuned to use lower octane gasoline due to other influencing factors such as ignition timing, turbocharging technology, and Atkinson cycle technology. Generally, the higher the gasoline octane, the higher the octane number and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If the Lincoln Nautilus occasionally uses the wrong octane gasoline, simply switch back to the correct octane after the current tank is used up. However, prolonged use of the wrong octane can have the following effects: For vehicles designed for lower octane, using higher octane gasoline will not cause damage, but the increased octane can alter the fuel's ignition point, leading to delayed combustion. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. For vehicles designed for higher octane, using lower octane gasoline can cause engine knocking. The significantly lower octane reduces the fuel's ignition point, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance is created during the upward stroke. This resistance makes the engine run very unstably. Mild knocking may only increase noise without obvious engine damage, but severe knocking indicates serious engine issues, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, potentially leading to severe damage like cylinder scoring.
