How long can the car run with 80km of fuel displayed?
3 Answers
The car displaying 80km of fuel can run for approximately 1,000 kilometers. Here is an introduction about gasoline: 1. Introduction: Gasoline is a volatile, flammable hydrocarbon mixture liquid obtained from petroleum through distillation, cracking, or pyrolysis, primarily used as fuel for spark-ignited internal combustion engines. 2. Raw Materials: It mainly consists of organic compounds derived from crude oil distillation and various additives. Although gasoline yield varies depending on crude oil composition, typically, a barrel of 42 US gallons of crude oil can produce 19 US gallons of gasoline after refinery processing. 3. Function: The octane rating of gasoline measures the anti-knock properties of a specific gasoline mixture. Based on different octane ratings, gasoline is produced in several grades. Other chemicals are often added to gasoline to improve chemical stability and other performance characteristics, control corrosiveness, and maintain fuel system cleanliness.
After driving for so many years, I've realized that the dashboard showing 80 kilometers is just an estimate. It's calculated based on your previous average fuel consumption, but the actual distance you can travel is uncertain. For example, if you're driving steadily on the highway, you might actually reach 80 or even 90 kilometers. However, if you hit city traffic with constant stops and starts, fuel consumption spikes, and you might only get 60 kilometers before the warning light comes on. I've experienced this myself a few times—seeing that number only to end up stranded halfway, especially when climbing hills or using the air conditioning, which increases fuel consumption. For safety, don't rely too much on this display. Refuel when you have about 50 kilometers left to avoid getting stuck on the road. Also, don't calculate time too precisely. At an average speed of 50 km/h, it's roughly an hour and a half, but driving slower in the city takes longer. Maintaining good car habits, like keeping tire pressure optimal, might extend the distance slightly, but it's not a game-changer.
When picking up family members, I pay the most attention to the fuel gauge. Seeing 80 km, I think the actual distance might be less due to varying road conditions. On smooth highways, it might go a bit further, but during rush hour with frequent traffic lights, fuel consumption increases quickly, possibly leaving only 60 km. It's advisable to refuel as soon as possible, especially for long trips or at night, as having less than 40 km left is risky. Time estimation isn't precise—driving at 50 km/h would take about 1.6 hours, but in reality, with slowdowns and stops, it might extend to over two hours. Driving steadily, avoiding sudden braking, and not using the air conditioning can save fuel and extend the distance slightly. Safety is the top priority; don't gamble with luck.
