What type of fuel does the 2019 Passat use?
2 Answers
SAIC Volkswagen Passat uses 95-octane gasoline, which was originally known as 97-octane gasoline. 95-octane gasoline consists of 95% isooctane and 3% n-heptane. The fuel tank capacity of the 2019 Passat is 66 liters, while the 2017 Passat has a fuel tank capacity of 69 liters. Here is an introduction to 95-octane fuel: 1. 95-octane gasoline is composed of 95% isooctane and 3% n-heptane. High-octane gasoline should be used when the engine has a high compression ratio. If low-octane gasoline is used with a high compression ratio, it can cause abnormal combustion, leading to knocking, increased fuel consumption, and reduced driving power. 2. Before driving, owners should check the fuel gauge and calculate whether refueling is needed during the trip based on the distance and the fuel gauge reading. It is advisable to refuel in advance rather than waiting for the fuel warning light to come on. The fuel pump is located inside the fuel tank and operates at a high temperature when continuously working. Being immersed in fuel helps to cool it effectively. When the fuel warning light comes on, it indicates that the fuel level is below the fuel pump. If you always wait for the light to come on before refueling, it will shorten the fuel pump's lifespan, and having too little fuel in the tank may even burn out the fuel pump.
I've driven Volkswagen cars for many years and am very familiar with the fuel grade requirements for the 2019 Passat. This car absolutely recommends using 95-octane gasoline - never try to save money by using 92-octane. The reason is simple: Volkswagen engines have high compression ratios, and low-grade fuel can easily cause knocking (that engine pinging noise), which may damage valves and pistons over time. I've checked the manual - the official recommendation is 95-octane or higher for optimal performance. In actual driving, 95-octane fuel makes acceleration smoother and fuel consumption more stable. A quick reminder: fuel quality matters. Choose reputable gas stations like Sinopec and avoid small stations with impure fuel. Engine maintenance starts with these small details - don't overlook them.
