What is the gasoline grade of Jetta VS5?
2 Answers
Jetta VS5 uses 92 octane gasoline. Gasoline grade: It refers to the ratio of the actual gasoline's anti-knock performance to that of standard gasoline. The higher the grade, the stronger the anti-knock performance. Standard gasoline is composed of isooctane and n-heptane. Higher grades are not necessarily better; the appropriate gasoline grade should be selected based on the engine's compression ratio. In December 2011, Beijing proposed changing the gasoline grades from "90, 93, 97" to "89, 92, 95" and stipulated that the sulfur content should not exceed 0.1%. How is the gasoline grade for a car determined: The gasoline grade for a vehicle should follow the manufacturer's recommended grade. If the recommended grade is 93, then 93 octane gasoline should be used. In emergency situations, 97 octane can be used. If the recommended grade is 97, then 97 octane must be used, and using 93 octane will shorten the engine's lifespan.
I've been driving the Jetta VS5 for several years. The manufacturer recommends using 92-octane unleaded gasoline, and I've always followed this advice. The car runs very smoothly. Occasionally, I've used 95-octane gasoline and felt a slightly quicker acceleration, but it's not necessary and not cost-effective. If lower-octane fuel like 90 is used, the engine might knock or even damage components, so I always double-check the fuel pump label when refueling. Additionally, regular maintenance is crucial, such as changing the engine oil and air filter, to keep the engine in good condition. The car's fuel consumption in the city is quite economical, averaging around 7-8 liters per 100 kilometers. For new owners, it's advisable to check the recommended fuel grade directly from the manual.
