What type of fuel does the 2019 Passat use?
4 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.
As a long-time Passat owner, I must remind you: the 2019 Passat's engine design is quite delicate and requires 95-octane gasoline. I've been using 95-octane exclusively for three years, and the engine has remained rock-solid. Lower-grade fuel can cause premature ignition, increasing wear and tear. If engine knocking occurs, you'll face costly repairs. The manual clearly states that 95-octane is the standard requirement—don't try to cut corners to save money. This is where worry-free driving comes into play—using quality fuel. By the way, always check the fuel label before filling up to ensure the correct octane rating—it's crucial for extending your car's lifespan. Fuel octane selection affects emissions and environmental protection. Using the wrong fuel may trigger the check engine light, and nothing's worse than having your trip delayed.
After purchasing my 2019 Passat, the dealership repeatedly emphasized using 95-octane gasoline. Initially, I tried 92-octane to save money, but fuel consumption skyrocketed and the engine sounded strange. Switching back to 95-octane immediately resolved the issues. The Volkswagen manual clearly states that this model requires 95-octane fuel, as higher octane prevents engine problems and improves acceleration response. Fuel choice has major consequences—long-term use of lower-octane fuel causes carbon buildup, leading to costlier repairs. Driving habits also affect fuel efficiency, such as avoiding sudden acceleration. In short, don’t skimp on gasoline—use 95-octane to protect your car.
