Why does the Jetta VS5 require 95-octane gasoline?
1 Answers
The reason the Jetta VS5 uses 95-octane gasoline is to ensure stable engine operation and optimal combustion conditions with higher-octane fuel. Avoid overfilling the tank: Overfilling can easily block the fuel tank vent. Once the vent is blocked, the internal pressure of the tank will drop below normal levels, leading to poor fuel supply or even fuel cutoff. Overfilling also increases the vehicle's weight, thereby increasing fuel consumption. Additionally, gasoline can deteriorate, posing potential safety hazards. Refuel before the warning light appears: While driving, always monitor the fuel gauge. When the indicator shows only a quarter of the tank remaining, it's time to refuel. If the tank remains empty for too long, the temperature difference between inside and outside can cause condensation inside the tank. This moisture can corrode the tank, affect fuel quality, and increase the engine's workload.
