Leftover engine oil from maintenance can be saved for next use, but it's important to note that the shelf life of opened engine oil will be shortened, generally to only 1 year. Below is relevant information about engine oil: 1. Functions of engine oil: The main functions of engine oil are lubrication, cleaning, and heat dissipation. In fact, many parts of a vehicle use engine oil, but the oil that needs to be changed every 5000 kilometers refers to engine oil. Most people generally use semi-synthetic or fully synthetic engine oil, while conventional engine oil is rarely used. Conventional engine oil is usually used in agricultural machinery, tricycles, and motorcycles. 2. Replacement intervals: Conventional engine oil, 5000 kilometers; semi-synthetic engine oil, 7500 kilometers; fully synthetic engine oil can go up to 10000 kilometers before the next maintenance.

Deduction Criteria for Parallel Parking

Body of the vehicle crossing the line: 100 points deduction. Wheels touching or pressing the lane boundary line while moving: 10 points deduction. Failing to park within the designated area: 100 points deduction. Not turning on the left turn signal when starting: 10 points deduction. Stopping midway: 100 points deduction. Below is relevant information about parallel parking: 1. Concept: Parallel parking is a part of the driving test (Subject 2). It is increasingly common in urban areas, especially when parking spaces in formal parking lots are in short supply. Many places have designated parking spaces along the sides of streets, known as "parallel parking spaces." 2. Parking technique: It is crucial that the position of the car before moving into the space is close to the left line of the parking space. Adjust both side mirrors—the left mirror should be lowered enough to see the left rear wheel, and the right mirror should allow visibility of the car body.

What does it mean when the Mercedes-Benz run-flat indicator stops working?

The Mercedes-Benz run-flat indicator stopping operation means the system has detected abnormal tire pressure in at least one tire. Below is extended information about Mercedes-Benz: 1. Interior and Exterior Configuration: The well-balanced SLK roadster is equipped with a 4-cylinder 2.3L large turbocharged engine, delivering a maximum output of 193 horsepower. It consumes 8.2 liters per 100 kilometers, accelerates from 0-100 km/h in just 6 seconds, and has a top speed of 237 km/h. The engine features a variable valve timing system that works in conjunction with electronically controlled magnets, adjusting valve opening and closing times based on camshaft and piston movement. 2. Cultural Essence Sedan: Every Mercedes-Benz model tells an extraordinary story, with the all-new E-Class sedan particularly embodying the brand's cultural essence. Its aerodynamic design reduces the drag coefficient to 0.27, enhancing agility while improving fuel efficiency. The expanded impact buffer zones for frontal and rear collisions far exceed the most stringent safety standards.

Should I Remove a Nail from My Car Tire?

Tire punctured by a nail but not leaking air is not recommended to pull out, because if the nail has already penetrated the tire, removing it may cause severe air leakage, rendering the vehicle undrivable; moreover, if the tire pressure is high, removing the nail might even lead to a tire blowout. There are two scenarios of tire air leakage as follows: 1. Rapid leakage: When removing the nail from the tire, you can hear the sound of air escaping, and it's visibly apparent that the tire loses pressure and deflates. In this case, you must not continue driving, as it may cause wheel rim deformation and poses extreme driving hazards. The correct approach is to stay where you are and seek assistance. 2. Slow leakage: When removing the nail from the tire, if there's no obvious air leakage, it indicates a very slow leakage rate, allowing you to drive slowly to the nearest repair shop for patching or replacement.

Can a car not under my name be traded in?

A car not under your name cannot be traded in. Here are the relevant details: 1. Required documents: The vehicle trade-in process requires the original vehicle's green book (registration certificate), the vehicle's license, and the original owner's ID card to proceed with the trade-in. Therefore, if the car to be traded in is not under your name, but you have all the necessary documents and the consent of the original owner, a trade-in is possible. 2. Trade-in explanation: Most 4S dealerships offer trade-in services for purchasing new cars. This means if your old car is of the same brand, you can use its residual value to offset part of the cost of the new car, and then pay the remaining amount to take delivery. In simple terms, it's selling your old car to buy a new one of the same brand, but the old car is sold to the 4S dealership instead.
