How to Use Toothpaste to Treat Car Body Scratches?

Methods for treating car body scratches with toothpaste: 1. First, spray water on the scratch with a small spray bottle, then wipe the scratched area clean with a tissue; 2. Apply toothpaste to the scratch and gently rub and spread it over the scratch and surrounding area with your hand and a tissue; 3. After half a minute, spread the toothpaste evenly on the car body; 4. Wait another half a minute, then slowly wipe the toothpaste off the car body with a tissue. Once all the toothpaste is removed, gently polish the area. If the scratches on the paint surface are very visible, it is recommended to use a touch-up pen for treatment. Be sure to know the official name of your car's paint color, then purchase a touch-up pen of the corresponding color. For deeper scratches, it is advisable to visit a car wash shop and have professionals help with the repair.

What is the professional name for the rear wing on a sports car?

The rear wing on a sports car is called a spoiler. It is part of the car's aerodynamic kit. The main function of a car spoiler is to reduce the lift at the rear of the vehicle. If the lift at the rear is greater than the lift at the front, it can lead to excessive steering, reduced rear-wheel grip, and poor high-speed stability. The design principle of a car spoiler is inspired by the design of an aircraft's tail wing. For a long time, this design was widely used in racing cars before being adopted for ordinary vehicles. The proper design of a spoiler also directly affects racing performance. There is an angled relationship between the nose wing and the rear wing of a racing car, which helps the car navigate turns safely and quickly on the track. This allows the car to achieve good downforce in corners while controlling wind resistance on straightaways. Functions of a spoiler: The primary function is to effectively reduce air resistance and save fuel when the car is driving at high speeds. During driving, resistance can be divided into three types: longitudinal, lateral, and vertical lift forces. Tests show that when a car moves forward at 80 km/h, 60% of fuel consumption is used to overcome longitudinal wind resistance. To effectively reduce and counteract the impact of air resistance at high speeds, car spoilers were designed. Their role is to generate a fourth type of force from the air—ground adhesion—which can partially offset lift, control the car's tendency to rise, reduce wind resistance effects, and keep the car firmly pressed against the road, thereby improving driving stability. The shape and size of a car spoiler are precisely calculated by designers—it should not be too large or too small, as this could either increase driving resistance or fail to serve its intended purpose.

Is a Car Considered a Stock Car After Three Months?

A car that has been in stock for three months is not considered a stock car. Generally, a stock car refers to a vehicle that has remained unsold for more than three months after being manufactured and leaving the factory. In essence, most stock cars are stored in open-air parking lots, exposed to sun and rain, without basic maintenance. This can lead to issues such as moisture damage and aging of various fluids, electronic components, batteries, rubber seals, and tires. If the stock time exceeds one year, you can request the dealership to replace the original engine oil. Additionally, check the production date of the tires—new tires older than two years may face rubber aging risks, so it’s advisable to ask the dealership to replace them as well. If these two aspects are addressed, such a stock car should not affect its usability. If the stock time approaches five years, it’s not recommended to purchase such a vehicle unless the discount is substantial. A five-year stock period means the engine oil, tires, rubber bushings in the suspension, and dust covers on the universal joints may all need replacement due to aging.

What is SAE 10W-30 engine oil?

Engine oil SAE 10W-30 is referred to as a "multi-grade" oil. The smaller the number in SAE 10W (such as 10 in this example), the less likely the oil is to become viscous at low temperatures. Here is an introduction to engine oil: Introduction to engine oil: Engine oil, also known as engine lubricating oil, is called Engine-oil in English. It has a density of approximately 0.91×10 (kg/m³) and serves functions such as lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, and shock absorption. It is hailed as the "blood" of a car. Composition of engine oil: Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties. Additives can compensate for and improve the shortcomings of the base oil's performance, imparting certain new properties, making them an important part of lubricating oil.

What is the minimum speed a car should not go below in third gear?

When driving in third gear, the speed of the car should not be lower than 20 km/h. The corresponding speed range for third gear is 20-40 km/h. Speed ranges for different gears: First gear corresponds to a speed range of 0-5 km/h. Second gear corresponds to 5-20 km/h, third gear to 20-40 km/h, fourth gear to 40-60 km/h, and fifth gear to 60-100 km/h. The relationship between car gears and speed: When downshifting, follow the principle of deceleration before downshifting. You can skip gears if necessary. When the speed matches the gear, the car's performance is at its best, and fuel efficiency is highest. If the speed does not match the gear, such as high speed with low gear or low speed with high gear, it not only increases fuel consumption but also causes irreversible damage to the engine and transmission. Therefore, it is essential to maintain the correct gear-speed match while driving.
