Can 98 and 95 gasoline be mixed?

95 and 98 gasoline cannot be mixed, as mixing them can cause engine knocking. Gasoline is a mixture, and while the chemical compositions of the two are relatively similar with strong anti-knock properties, it is recommended to use them separately to ensure vehicle safety. The difference between 98 and 95 gasoline lies in their octane ratings and quality levels. The specific details are as follows: Different octane ratings: 92 gasoline contains 92% isooctane and 8% n-heptane. 95 gasoline: consists of 95% isooctane and 3% n-heptane. Different gasoline quality levels: The gasoline grade represents the octane rating of the fuel. A higher grade indicates a higher octane rating, which means better anti-knock performance. This results in smoother engine operation, reduced vehicle wear, and better engine protection. It is suggested that using a higher-grade gasoline in a vehicle designed for a lower grade will not cause damage, but the increase in octane rating can alter the fuel's ignition point, leading to delayed combustion in the engine. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. Using lower-grade gasoline in a vehicle designed for a higher grade can cause engine knocking. A significantly lower octane rating reduces the gasoline's ignition point, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance will arise during the upward stroke, making the engine run very unstably. Mild knocking may only increase noise without obvious engine damage, but noticeable knocking indicates severe engine conditions. The vibration affects not only driving stability but also causes abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring.

What is the engine number of the Great Wall M4?

Great Wall M4 is equipped with a 1.5L naturally aspirated engine, and the engine number is GW4G15. Here is an introduction about the engine number: 1. The engine model is marked by the manufacturer according to relevant regulations or industry practices to indicate the relevant information of the engine. This includes the production enterprise, specifications, performance, characteristics, technology, purpose, and product batch of the engine. 2. The engine number is like the ID card of the engine, which can be used to query its main information, including the product series code, replacement symbol, regional and enterprise code. The manufacturer can choose the corresponding letters as needed, but they must be approved and filed by the industry standard standardization unit.

What tires does the Lexus ES use?

The Lexus ES uses Yokohama tires. The tire size for the 2.0L model is 215/55R17, and for the 2.5L model, it is 235/40R19. Yokohama Tire, founded in 1917 and formerly known as Yokohama Rubber, officially changed its name in China to Yokohama in 2008. It has developed tire design technology that reduces air resistance during vehicle operation. For the Lexus ES tires in daily use, pay attention to the following points: Regularly check the tire surface for cracks, deformations, or other defects. Due to wear from driving, the tread grooves gradually become shallow. If the tread wears out, it will lose its drainage and anti-slip functions, significantly reducing the car's performance. Small cracks can also pose a risk of tire blowouts at high speeds. Additionally, promptly remove any pebbles lodged in the grooves. Try to park on flat ground. Avoid parking on roads with thick, sharp, or pointed stones. Do not park near or in contact with petroleum products, acids, or other materials that can deteriorate rubber. After parking, do not turn the steering wheel, as this can accelerate tire wear. Do not splash water to cool the tires. In hot weather or during high-speed driving, tires can overheat, increasing air pressure. In such cases, stop to allow the tires to cool naturally. Avoid releasing air to reduce pressure or splashing water to cool the tires, as this can cause abnormal aging of the tread rubber. Avoid sudden braking. Try to minimize frequent use of brakes and hard braking to prevent accelerated tread wear from dragging against the ground.

How to Adjust the Rearview Mirror on the Tiguan?

The adjustment of the rearview mirror on the Tiguan can be done by pressing the circular button on the mirror to move it up, down, left, or right, corresponding to the desired direction. To adjust the left rearview mirror, move the circular button to the L position, and so on for the others. The specific adjustment positions are as follows: 1. Adjust the horizon reflection in the left rearview mirror to the center of the mirror. 2. Adjust the reflection of the left side of the vehicle to occupy the right quarter of the mirror. 3. Adjust the horizon reflection in the right rearview mirror to two-thirds of the mirror's height. 4. Adjust the reflection of the right side of the vehicle to occupy the left quarter of the mirror.
