What is the Difference Between Engine Oil and Fuel?

There are five main differences between engine oil and fuel, namely different definitions, sources, functions, types, and locations. Different Definitions: Engine oil, also known as engine lubricant, is not a type of fuel oil but rather a driving agent for fuel oil. Fuel, on the other hand, is an important type of engine fuel, categorized as gasoline or diesel. Different Sources: Engine oil is primarily composed of base oils and various functional additives, where the base oils are non-volatile oils extracted from plant seeds, flowers, roots, or fruits. Fuel, however, is a mixture of various oils and residues that are refined and purified in oil refineries. Different Functions: Engine oil mainly serves to lubricate and reduce friction in the engine, assist in cooling, seal against leaks, prevent rust and corrosion, and act as a shock absorber, thereby extending the vehicle's lifespan. Fuel, when burned, generates energy to power the engine. Different Types: Fuel types include gasoline, kerosene, diesel, and residual oil. Engine oil types include gasoline engine oil, full synthetic oil, mineral oil, etc. Different vehicles must select the appropriate engine oil and fuel based on their configurations. Different Locations: Due to its low ignition point, gasoline is typically stored far from the engine, usually at the bottom of one side of the vehicle. Engine oil, with its higher ignition point, is stored near the engine, often at the front of the car. Different Refill Times: Fuel is consumed relatively quickly in a vehicle and must be replenished based on the vehicle's usage frequency to ensure normal operation. Engine oil, however, is replaced according to specific usage cycles rather than being refilled. Different Prices: Naturally, the prices of fuel and engine oil differ. Fuel prices fluctuate significantly, while engine oil prices remain relatively stable. Different Characteristics: Engine oil is a lubricant, whereas fuel is gasoline or diesel. Engine oil is used to lubricate friction surfaces of components, while fuel provides power. Engine oil is a synthetic oil that lubricates, reduces wear, and extends vehicle lifespan. Fuel is a mixture of various combustible materials. Engine oil is synthetic, divided into semi-synthetic and full-synthetic oils, with similar performance and functions but differing lifespans. Semi-synthetic oil requires replacement every 5,000 kilometers, while full-synthetic oil can last up to 10,000 kilometers. Fuel is a mixture of various oils and residues, distilled and purified, then separated by temperature to remove impurities. Engine oil is often referred to as the "blood" of a car. It consists of base oils and additives. Base oils are the main component of lubricants, determining their fundamental properties, while additives compensate for and enhance the performance of base oils, providing new characteristics and making them a crucial part of lubricants. Fuel is divided into gasoline and diesel. These are volatile, flammable hydrocarbon mixture liquids derived from petroleum through distillation, cracking, or pyrolysis, used as fuel. Gasoline appears as a transparent liquid, is flammable, and primarily consists of C5–C12 aliphatic and cycloalkane hydrocarbons, along with a certain amount of aromatic hydrocarbons. Gasoline has a high octane rating (anti-knock combustion performance) and is graded by octane levels such as 89, 90, 92, 93, 95, 97, and 98. In January 2012, gasoline grades 90, 93, and 97 were revised to 89, 92, and 95, respectively. Diesel has a higher sulfur content than gasoline. This harmful substance forms sulfuric or sulfurous acid during combustion, which, along with high-temperature and high-pressure exhaust gases, enters the oil pan, accelerating the oxidation and degradation of engine oil. Therefore, diesel engine oil formulations require more antioxidants and additives to maintain a stronger alkaline state. Gasoline engine oil does not have such stringent requirements in this regard. If used in diesel engines, it would quickly degrade due to corrosion from acidic gases.

What Are the Effects of Diluting Antifreeze with Water?

After adding water to automotive antifreeze, the performance of the antifreeze will decrease. The full name of antifreeze is antifreeze coolant, meaning a coolant with antifreeze properties. Antifreeze prevents the coolant from freezing and expanding in cold winter conditions, which could otherwise crack the radiator or damage the engine block or cylinder head. Functions of Antifreeze: Antifreeze is a coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent properties such as preventing freezing in winter, boiling in summer, and providing year-round protection against scale and corrosion. Composition of Antifreeze: The main components of antifreeze are 50% pure water, 40% methanol, and 10% other substances. Types of Antifreeze: Antifreeze is generally divided into three types: ethanol-water type, glycerol-water type, and ethylene glycol-water type. Can Different Antifreeze Brands Be Mixed? It is necessary to use the same brand of antifreeze. Different brands of antifreeze may have varying production formulas, and mixing them could lead to chemical reactions between multiple additives, rendering the additives ineffective.

Why is the 360-degree reversing camera not displaying?

Here are the possible reasons why the 360-degree reversing camera is not displaying: 1. The data cable connected to the reversing camera is loose or has poor contact. 2. The reversing camera is damaged. 3. Malfunction of the gear position sensor. Below are some tips for using the reversing camera: 1. Before reversing, first check the situation behind the vehicle, estimate the reversing route, and ensure that during the reversing process, try not to accelerate and control the speed to avoid going too fast. 2. During the reversing process, do not only look at the rear view; while ensuring the safety behind, occasionally observe the left and right rearview mirrors, paying attention to the distance between obstacles and the vehicle body, and use the steering wheel to adjust the vehicle's position accordingly. 3. If you feel that the front of the vehicle might hit an obstacle during reversing, you should also check the front at appropriate times to avoid collisions. Especially when the steering wheel is turned significantly, since the turning radius of the front wheels is larger than that of the rear wheels during the turning process, the front of the vehicle will swing outward more during reversing, so it is essential to pay attention to the front to prevent scraping.

What does ODO on the dashboard mean?

ODO in a car represents the total mileage the vehicle has traveled. ODO is an abbreviation of the English word odograph (indicating total mileage, automatic odometer). In contrast, TRIP in the English word means short-distance mileage, also known as the trip mileage, which is convenient for users to calculate the kilometers traveled for each trip, i.e., the distance recorded after manually resetting the odometer. Below are the meanings of other automotive terms: 1. ECO: ECO indicates that the car has activated the energy-saving mode, which has little impact on the vehicle itself. The main principle is to comprehensively judge the gear of the automatic transmission, engine speed, and transmission oil temperature during driving, control the engine speed with reasonable gears, and finally, the computer calculates the optimal fuel amount to be supplied to the engine for operation. The original design concept was based on environmental and economic considerations to achieve fuel savings. 2. PS: The PS displayed on the car dashboard is the steering wheel lock indicator, and the steering wheel lock light disappears after starting the engine. 3. AC: The AC button is the switch for the car air conditioning's cooling function, meaning that the air conditioning compressor will only work when this button is pressed, and the air blown out by the blower will be cold.

What are the pros and cons of modifying the exhaust system?

Pros of modifying the exhaust system: 1. Enhances visual appeal; 2. Improves auditory experience; 3. Reduces exhaust backpressure, benefiting vehicle performance at high RPMs. Cons of modifying the exhaust system: 1. If the catalytic converter is altered, the vehicle may fail emissions tests; 2. Modifying the muffler can change exhaust backpressure, affecting exhaust noise and potentially causing abnormal sounds; 3. Changes in the weight of the entire exhaust muffler system can alter vibration and noise, and may lead to fractures during use. Functions of the exhaust pipe: 1. Reduces vibration and noise, extending the lifespan of the exhaust muffler system: When exhaust gases leave the engine at high pressure, they produce unacceptable noise levels. The exhaust pipe plays a key role in noise reduction. 2. Emissions control: Its core components are the catalytic converter and muffler. The catalytic converter transforms harmful gases like CO, HC, and NOx from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions.

What Causes the Rustling Sound When Raising or Lowering the Car Window?

Reasons for abnormal noises when raising or lowering car windows: 1. Aging of the window glass seal strip. After the seal strip ages, the friction increases, leading to abnormal noises. This condition is more noticeable in summer because the aged seal strip expands more under direct sunlight, increasing friction and thus worsening the noise. 2. Dirt accumulation in the gap between the glass and the seal strip. Particles in the dust rubbing against the glass can also cause abnormal noises. 3. Dirty glass tracks or a malfunctioning lift motor. Daily maintenance tips for car glass: 1. Assess the damage to the car glass to determine whether it needs replacement or repair. 2. Identify the type of car glass required for replacement based on the vehicle model and part number, and develop an operation plan. 3. Use professional tools such as pneumatic, electric, or manual tools to apply specialized adhesive for car glass and to remove or install the glass. 4. Use instruments and meters to inspect, test, and repair control circuits and electronic components related to car glass, addressing any electrical or mechanical issues that arise during installation. 5. Use testing tools to check the sealing performance of the replaced car glass.
