Can 95 Octane and 92 Octane Gasoline Be Mixed?

95 octane and 92 octane gasoline should not be mixed. Long-term mixing of different octane ratings can affect the lifespan of the car's ignition system, fuel injectors, and spark plugs. Gasoline is a volatile, flammable hydrocarbon mixture liquid distilled or cracked from petroleum, used as fuel, and appears as a transparent liquid. 95 octane gasoline consists of 95% isooctane and 5% n-heptane, while 92 octane gasoline consists of 92% isooctane and 8% n-heptane. The main difference between the two lies in the purity of isooctane—the higher the purity of isooctane, the stronger the gasoline's anti-knock performance.

What does increased driving resistance mean?

The driving resistance of a car includes four parts: the rolling resistance between the tires and the ground, air resistance, gradient resistance, and acceleration resistance. In other words, these are the factors that affect the speed of the car while driving. Increased friction affects the engine's power output, causing excessive pressure. The related introduction is as follows: 1. Gradient resistance: When a car travels at a constant speed on a horizontal road, it must overcome the rolling resistance from the ground and the air resistance from the atmosphere. When the car travels uphill on a slope, it must also overcome the component of gravity along the slope, which is called gradient resistance. When the car accelerates, it also needs to overcome acceleration resistance. Rolling resistance and air resistance exist under any driving conditions, while gradient resistance and acceleration resistance only exist under certain driving conditions. There is no gradient resistance or acceleration resistance when driving at a constant speed on a horizontal road. 2. Rolling resistance: When the wheels roll, the contact area between the tires and the road surface generates normal and tangential interaction forces, as well as corresponding deformation of the tires and the supporting road surface. The relative stiffness of the tires and the supporting surface determines the characteristics of the deformation. When elastic tires roll on hard road surfaces (concrete roads, asphalt roads), the deformation of the tires is the main factor. At this time, due to the internal friction of the tires, elastic hysteresis loss occurs, and the work done to deform the tires cannot be fully recovered. It is this elastic hysteresis loss of the tires that causes rolling resistance.

What is the aspect ratio?

Aspect ratio refers to the ratio of the height from the rim to the tread surface to the measured width of the tire's cross-section, expressed as a percentage, meaning the height as a percentage of the width. The functions of tires are: 1. Transmit driving force, braking force, and steering force to achieve vehicle operation; 2. Support vehicle load; 3. Reduce and absorb vibrations and impacts during driving, avoiding severe vibrations that could damage vehicle components. Tire maintenance methods include: 1. Regularly clean stones stuck in tire treads; 2. Minimize exposure to direct sunlight; 3. Promptly check tire pressure; 4. Pay attention to suspension maintenance; 5. Periodically inspect front wheel alignment; 6. Adopt careful driving habits, choose road surfaces wisely, avoid objects that could puncture or scratch tires, and steer clear of chemical spills that may corrode tires.
