What is the normal service life of an oil seal?

[GraceDella]

Automotive transmission shaft oil seals (dynamic seals) can normally ensure no oil leakage for 200,000-300,000 kilometers. Here are specific details about fuel consumption: 1. Fuel consumption: High-displacement vehicles consume as much fuel as family cars. 2. Comparison: For 100 kilometers, a 6-liter fuel consumption is observed. On the same route, a 1.6L Octavia consumes 7 liters. Sports cars typically require much higher throttle input, consuming more fuel than street cars. During aggressive acceleration or high-speed runs, a liter-class sports car's fuel consumption is comparable to that of a 3.0L car's combined fuel consumption. 3. Fuel: Most cars use gasoline, so the energy content is the same. The Octavia's relatively higher fuel consumption stems from high aerodynamic drag, a compact structure limiting fuel-saving technology implementation, and a high-revving, power-focused design philosophy.
