Should Engine Oil Be Thin or Thick?

Engine oil tends to thicken over time. The main reasons are: 1. As time passes, the oil becomes increasingly viscous: transitioning from clear to cloudy, and the accumulation of impurities naturally increases its thickness. At its extreme, it can turn into a thick, asphalt-like consistency. 2. Oil thinning to a water-like consistency: Thinning of oil can indeed lead to excessively low oil pressure, resulting in semi-dry or dry friction between various engine components. Here is some additional information: 1. Introduction and functions: Engine oil, also known as motor lubricant, serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption for the engine. It is often referred to as the 'lifeblood' of a car. 2. Composition: Engine oil consists of base oil and additives. The base oil is the primary component of the lubricant, determining its fundamental properties, while additives compensate for and enhance the shortcomings of the base oil, imparting new characteristics. Additives are a crucial part of the lubricant.

What kind of engine oil should be used for the new Mondeo 2.0T?

The new Mondeo 2.0T version uses 5W-30 semi-synthetic engine oil, while the 1.5T model requires 5W-20 full-synthetic engine oil. It is important to note that different brands and grades of engine oil should not be mixed, as this can affect their performance and, in severe cases, damage the car engine. Below is an introduction to the functions of engine oil: 1. Lubrication to reduce wear: Between the piston and cylinder of the engine, the relative sliding of the main shaft and bearing bush causes wear. Engine oil forms a thick oil film between the two sliding surfaces, separating the surfaces of the relatively sliding parts to reduce wear. 2. Cooling and temperature reduction: Engine oil carries heat back to the oil tank and then dissipates it into the air, helping the radiator cool the engine. 3. Cleaning and purification: Engine oil circulates carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank, flushing away dirt generated on the parts through the flow of the lubricating oil.

What is the Difference Between Calibration and Bench Testing?

Simply put, calibration is a process of optimizing various control parameters of each control unit. Bench testing, on the other hand, refers to testing the quality of gasoline, engine oil, diesel, gear oil, etc., by simulating the operation process of an automobile engine. It generally belongs to large-scale projects, which require the cooperation of various instruments and equipment for data detection. Additional information is as follows: 1. Gasoline engine bench testing: The results of gasoline engine bench testing are the basis for determining the quality grade of gasoline engine oil. For example, the MS-II D engine test: used to evaluate the ability of lubricating oil to prevent rust or corrosion of the valve group under low-temperature and short-distance driving conditions, and to evaluate API, SE, SF, and SG grade gasoline engine oils. The Chinese standard test method includes SH/T-0512 gasoline engine oil low-temperature rust evaluation method (MS Procedure II D method). 2. Engine principle: Engine calibration, in the final analysis, is a process of optimizing intake, fuel injection, and ignition control. Engine matching work is to set appropriate values for various parameters of the engine control unit (ECU) through various project matches under a certain engine management system (EMS) to meet the requirements of the best air-fuel ratio and the best ignition advance angle for each working condition determined by the car's power, economy, reliability, safety, and emission performance.

What does a yellow exclamation mark in Volkswagen indicate?

When a yellow exclamation mark appears on the car dashboard, it indicates one of four possible issues: general fault, automatic transmission fault, abnormal tire pressure, or lighting fault. Below is a detailed analysis of these four scenarios: General Fault: A triangle with an exclamation mark inside indicates a malfunction in the car's general performance or components and functions. Common causes include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor failure. It is recommended to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a transmission malfunction or transmission lubricant level below the normal range. Transmission fluid should be replaced promptly. Abnormal Tire Pressure: An exclamation mark inside a horizontal line under a parenthesis represents the tire pressure monitoring warning light. This light illuminates when the car's tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a malfunction in one of the car's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue. Additionally, a red exclamation mark inside a circle with parentheses indicates a brake system warning, typically due to brake system failure or low brake fluid level. Immediate inspection of the brake system is necessary to avoid accidents.

What is the purpose of purchasing car insurance?

Car insurance is a type of property insurance, also known as motor vehicle insurance. It refers to a commercial insurance that compensates for personal injury, death, or property damage caused by natural disasters or accidents involving motor vehicles. Below is an introduction to the roles of various types of car insurance: 1. Compulsory Traffic Insurance: This is a mandatory insurance required by the state, which compensates for the losses of third-party victims within the liability limits in the event of a traffic accident. 2. Third-Party Liability Insurance: Commonly referred to as 'Three-Party Insurance,' it compensates for the direct losses of third parties in accidents involving personal injury, death, or property damage. It serves as the strongest supplement to Compulsory Traffic Insurance in terms of coverage, with optional coverage ranging from hundreds of thousands to millions. 3. Vehicle Damage Insurance: This insurance compensates for the shortcomings of Compulsory Traffic Insurance and Third-Party Liability Insurance, which do not cover damages to the insured's own vehicle. Daily driving inevitably involves minor collisions, and without Vehicle Damage Insurance, the repair costs would have to be borne by the vehicle owner. 4. No-Deductible Insurance: Vehicle Damage Insurance and Third-Party Liability Insurance set different deductible rates based on accident liability. To minimize personal losses, vehicle owners can purchase No-Deductible Insurance as an add-on, transferring their share of the liability back to the insurance company. 5. Theft and Robbery Insurance: Comprehensive Theft and Robbery Insurance covers situations where the insured vehicle is stolen or robbed under non-intentional, non-deliberate, and non-violation circumstances. If the case remains unsolved after reporting and investigation within a certain period, the insurance company compensates for the corresponding losses.

What type of engine oil is used for the Audi Q7?

Audi Q7 originally uses 0W30 - Castrol EDGE engine oil. For later maintenance and oil changes, you can choose Audi-specific engine oil, Mobil 1, or Shell synthetic oil. The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under both low and high-temperature conditions. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, resulting in smoother cold starts for the car. The latter number represents the kinematic viscosity of the oil at 100°C. The higher the value, the better it maintains viscosity under high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the engine oil in an Audi Q7 is as follows: Wait for the engine temperature to drop, allowing the oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug and place an oil pan underneath to catch the old oil until it stops flowing. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain out; Use a specialized wrench to remove the oil filter; Apply oil to the seal of the new oil filter and tighten it clockwise by hand; Add the new engine oil through the filler cap on the engine valve cover, typically filling up to three-quarters of the oil container; Start the engine and let it run for 5 minutes, then check for any leaks around the oil drain plug and oil filter. If leaks are found, repairs should be made; After stopping the engine, pull out the oil dipstick and ensure the engine oil level is within the standard range.
