Can FAW-Volkswagen Jetta VS5 use 92 gasoline?
2 Answers
Jetta VS5 cannot use 92 gasoline. The Jetta VS5 is equipped with a 1.4-liter turbocharged engine across all models, and this vehicle requires a minimum of 95 gasoline. Generally, turbocharged engines require at least 95 gasoline. If 92 gasoline is used, the turbocharged engine is prone to knocking. Relevant information about gasoline is as follows: 1. The English name for gasoline is 'gasoline' or 'gas' (American English), also known as 'petrol' (British English). It is a volatile, flammable hydrocarbon mixture liquid distilled or cracked from petroleum, primarily used as fuel for spark-ignited internal combustion engines. 2. Gasoline with different octane ratings has different levels of octane; the higher the octane rating, the higher the octane level of the gasoline.
I've been driving my Jetta VS5 for over two years now. The manufacturer recommends using 95-octane gasoline, as the car is equipped with a 1.4T turbocharged engine with a high compression ratio that requires high-octane fuel to prevent knocking issues. When I used 92-octane gasoline, I noticed a significant drop in power, strange engine noises, and unstable RPM. Knocking is a metallic pinging sound caused by abnormal ignition, and prolonged use of 92-octane fuel may lead to piston or valve damage, resulting in costly repairs and downtime. While it's fine to use 92-octane in emergencies, I recommend making it a habit to use 95-octane to protect the engine's lifespan and save hassle. After all, a car is a means of transportation—proper maintenance ensures smoother and more comfortable driving.
