Is 92 or 95 gasoline better?

The difference between 92 and 95 gasoline is not about quality, but the different content of added isooctane, which affects the gasoline's anti-knock performance. Here is additional information about 95 and 92 gasoline: 1. 95 gasoline: 95 gasoline consists of 95% isooctane and 5% n-heptane. High-octane gasoline should be used when the engine has a high compression ratio. Using low-octane gasoline in a high-compression engine can cause abnormal combustion, leading to knocking, increased fuel consumption, and reduced driving power. 2. 92 gasoline: 92 gasoline has an octane rating of 92 and contains 8% n-heptane, making it suitable for mid-range vehicles with lower compression ratios. 3. Reason: Follow the manufacturer's recommendations for fuel type. Avoid long-term use of higher-octane gasoline, as it can alter ignition timing and may harm the engine, shortening its lifespan. Higher-octane gasoline can be used in emergencies, but lower-octane gasoline should never be used.

Is It Safe After Wheel Hub Deformation Repair?

It is not safe after wheel hub deformation repair, as there are still potential safety hazards even after the repair. If the wheel hub has become out-of-round, it cannot be repaired because the repair will still affect driving safety. The wheel hub is the rotating part of the wheel steel inside the tire, connected to the wheel core via columns, and it is the metal component that supports the center of the tire mounted on the axle. The maintenance methods for wheel hubs are: 1. When the vehicle is in a humid area, the wheel hub should be cleaned frequently to prevent salt from corroding the aluminum surface; 2. When necessary, after cleaning thoroughly, the wheel hub can be waxed for maintenance to keep it glossy; 3. When the wheel hub is at a high temperature, it should be allowed to cool naturally before cleaning. Do not use cold water to clean it, as this can damage the aluminum wheel hub, cause the brake disc to deform, and affect braking performance. Using cleaning agents on the wheel hub can cause chemical reactions on the surface, leading to loss of gloss.
