How many kilometers can the Jetta's reserve fuel tank run?
2 Answers
Jetta's reserve fuel tank can run approximately 600 kilometers. Purpose of the fuel tank: In the hydraulic system, besides storing fuel, the fuel tank also functions to dissipate heat, separate air bubbles from the oil, and precipitate impurities. The fuel tank is equipped with many accessories, such as coolers, heaters, air filters, and liquid level gauges. Fuel tank maintenance methods: The maintenance of the fuel tank mainly involves combining it with the car's primary maintenance. This includes draining accumulated water and sediment from the tank, checking for oil leaks at pipe joints and switches. For fuel tank caps equipped with air valves and steam valves, it's also necessary to check if the vent holes are clear. The filter screen at the fuel filler port should be kept intact to prevent impurities from entering the tank and clogging the fuel lines during refueling. The sealing gasket of the fuel filler cap should also be intact to prevent fuel from spilling out while driving.
Speaking of how many kilometers the Jetta's reserve fuel tank can last, I have quite some experience. I commute a lot with my Jetta, and it's common to see the fuel light come on. Generally, when the fuel light turns on, there are about 5 to 8 liters of fuel left in the tank. Fuel consumption varies depending on whether you're stuck in city traffic or cruising on the highway. In urban areas with higher fuel consumption, it might be over 10 liters per 100 kilometers, allowing you to drive only about 40 to 50 kilometers. On the highway, where fuel efficiency is better at around 6 liters per 100 kilometers, you might barely manage 70 to 80 kilometers. However, don't rely too much on this reserve. The fuel pump relies on fuel for cooling, and running out of fuel can cause overheating and damage, which can be expensive to repair. I recommend finding a gas station as soon as the fuel light comes on to avoid breaking down midway and causing delays. It's best to develop the habit of keeping an emergency fuel can in the car. Based on my experience with the older Jetta models, it's generally safe to drive within an average of 60 kilometers on the reserve fuel.
