Does the sound of chassis collision when going over a pothole affect the car?

Going over a pothole with a sound of chassis collision does affect the car. If the speed is too fast, it may puncture the oil pan, causing oil leakage. The solutions for this situation are as follows: Park and inspect: After a significant collision, you should stop and inspect the car. If oil leakage is found under the car, it is likely that the oil pan has been punctured. The oil pan is where the engine stores oil, which is used for engine lubrication and cooling. If not addressed promptly, it may lead to engine cylinder scoring or even complete failure. Stop driving: If severe shock absorber oil leakage is found after the collision, you should stop driving to prevent the shock oil from contaminating the brake system, which could significantly reduce braking performance and compromise safety.

What is the 0-100 km/h acceleration time of the Ruicheng CC?

The 0-100 km/h acceleration time of the Ruicheng CC is approximately 9 seconds. Introduction to 0-100 km/h acceleration: 0-100 km/h acceleration refers to the time it takes to accelerate from 0 to 100 kilometers per hour. Generally, compact cars with 1.6-liter engines achieve 0-100 km/h acceleration times between 11 to 13 seconds, while supercars typically accelerate in less than 3.8 seconds. Among vehicles with the same displacement, those equipped with turbocharged engines have a significant advantage in 0-100 km/h acceleration due to their more powerful output and a very wide range of maximum torque, allowing the vehicle to achieve maximum acceleration at very low RPMs. Factors affecting 0-100 km/h acceleration: Drive configuration: Most mainstream vehicles today are front-wheel drive, which puts them at a disadvantage during 0-100 km/h acceleration. During acceleration, the inertial force acting on the vehicle's center of gravity creates a moment that shifts most of the weight to the rear wheels. This means the rear wheels bear more load and can achieve greater traction, while the front wheels become relatively lighter, resulting in reduced traction and power loss.

What is the difference between Mobil Gold and Mobil Silver?

The differences between Mobil Gold and Mobil Silver include viscosity and base oil. Here are the detailed explanations: Different viscosity: Mobil Silver has three viscosity grades: 5w-30, 5w-40, and 5W-50, while Mobil Gold only has one viscosity grade: 0W-40. Different formulations: Mobil Silver typically uses MSDW hydroisomerized oil, commonly known as Group III+, which is no longer a true full synthetic. On the other hand, Mobil Gold uses Group IV PAO full synthetic base oil, and its additive formulation provides better anti-wear protection and low-temperature performance compared to Mobil Silver, making it more expensive.

What to do if there are oil stains on the car paint that cannot be washed off?

If it is stubborn stains, only strong cleaning agents can be used for cleaning. Below are the relevant methods for cleaning oil stains on car paint: New paint: Oil stains can cause fatal damage to the paint surface, so timely treatment is particularly important. If detected early, they can be wiped off directly with a cloth. If the paint or oil stains have been present for a long time: The paint surface will develop wrinkles, bubbles, cracks, and the so-called "orange peel" phenomenon. At this point, waxing alone can no longer handle the issue. It is necessary to use sandpaper specifically designed for car cleaning to remove the paint and oil stains, and then restore the car's surface gloss by waxing. If the corrosion is severe, the entire section of paint can be refurbished.

How to Deal with Yellow Stains on White Cars That Won't Come Off Like Rust Spots?

Solutions for yellow stains on white cars that won't come off like rust spots are as follows: If the yellow stains are relatively mild, you can evenly apply the car wax that comes with the vehicle to the stains, then wipe them off with a towel using a bit of force, and finally rinse with water. Those with professional detailing knowledge can use 3M detailing sandpaper to sand the stains, followed by polishing with a polishing machine and detailing polish. If you lack relevant experience, you can take the car to a professional auto detailing shop to perform the above steps to remove the yellow stains. Methods to deal with scratches on the car are as follows: Hairline scratches: Hairline scratches can usually be removed by polishing or applying a rubbing compound. Generally, a gentle wipe is enough to make the hairline scratches disappear. Moderate to deep scratches: Moderate and deep scratches cannot be repaired by rubbing. For small areas with a dent depth not exceeding 5mm, you can fill them with putty to level the surface, then proceed with touch-up painting.

Will Points Be Deducted for Deviating Direction During Gear Shifting?

Deviating direction during gear shifting does not result in point deductions, but it's best to avoid significant vehicle shaking, as it may be judged as speed mismatch. The following are gear shifting test techniques: Starting in First Gear: When starting the vehicle, use first gear. Ensure the clutch is fully depressed when shifting gears; otherwise, gear engagement may fail. Proper Gear Shifting: Speed and gear must match. Shift gears sequentially without skipping levels. When decelerating, reduce speed first before shifting gears. If a wrong gear is accidentally engaged, fully depress the clutch and re-engage the correct gear. Avoid Looking Down at Gears: Shift gears by feel without looking down. Keep eyes on the road ahead and constantly observe traffic conditions. Learners unfamiliar with gear shifting should practice more at driving school and cultivate the habit of avoiding looking down at gears during practice.
