Can the Jetta VS5 use 92 gasoline?
1 Answers
Jetta VS5 cannot use 92 gasoline. This vehicle is equipped with a 1.4L turbocharged engine, which requires a minimum of 95 gasoline. Different grades of gasoline have different octane ratings. The higher the grade, the higher the octane rating. Generally, 95 gasoline is the minimum requirement for turbocharged engines. Using 92 gasoline in a turbocharged engine can easily cause knocking. Knocking is an abnormal combustion phenomenon in the engine. When the piston moves upward to compress the combustible mixture, the temperature and pressure of the mixture increase. If the gasoline's anti-knock performance is poor, the combustible mixture may ignite prematurely, which is known as knocking. When knocking occurs, the piston is moving upward while the burning mixture pushes it downward, affecting the engine's power output and potentially causing damage to the engine.
