Both 92 and 95 octane gasoline are acceptable, but it is best to consistently use one type. There is essentially no significant difference between 92 and 95 octane gasoline, with the only distinction being the octane rating. 95 octane gasoline consists of 95% isooctane and 5% n-heptane, while 92 octane gasoline is composed of 92% isooctane and 8% n-heptane. Below is a related introduction: Gasoline Octane Rating: The gasoline octane ratings that car owners see actually refer to the ratio of the gasoline's anti-knock performance compared to standard gasoline. For example, 95 octane gasoline indicates that its anti-knock performance is the same as that of standard gasoline containing 95% isooctane and 5% n-heptane in research tests. This does not mean that the 95 octane gasoline used in daily life contains 95% octane. Higher Octane Does Not Mean Better Quality: Additionally, a higher octane rating only indicates better anti-knock performance and does not signify better gasoline quality or improved cleaning properties, as no experiment has proven this. Moreover, the vehicle manuals provided to car owners specify the appropriate type of gasoline for their models. It is advisable for car owners not to mix different types of gasoline to avoid causing engine knocking or damage.

How Often Should You Replace the Car Air Filter?

Generally, the car air filter should be replaced every six months or every 10,000 kilometers, but the replacement interval should be adjusted according to the actual driving conditions. In summer, if the vehicle frequently drives through water, dust may accumulate on the surface of the condenser, leading to poor heat dissipation and reduced air conditioning cooling efficiency. Additionally, bacteria can grow on the condenser surface. When you press the AC button and select the air intake mode (regardless of whether it's in internal or external circulation), the air drawn into the car passes through the evaporator, blower, and water channels. If the evaporator or blower harbors bacteria, dust, or other debris, these contaminants can be blown into the cabin. This is why the air filter is crucial—it should be cleaned regularly to extend its lifespan.

Can You Drive with Engine Knocking?

Engine knocking is not advisable to drive with. The causes of engine knocking include: 1. Carbon deposits: Incomplete combustion of fuel in the engine can lead to carbon buildup; 2. Overheating: Prolonged intense driving can cause the engine temperature to rise excessively. If the temperature reaches its upper limit, it can result in abnormal combustion of gases inside the engine, leading to knocking; 3. Poor fuel quality: Using low-quality fuel significantly reduces its anti-knock properties, making the engine more prone to knocking; 4. Ignition timing issues: If the car's ignition system malfunctions, causing ignition to occur before the piston reaches the correct position, it can lead to abnormal engine vibrations and, in severe cases, engine knocking.
