How Long Can a Car Drive When the Fuel Range Is Low?
2 Answers
When the fuel range of a car is low, it can theoretically still drive for about 50 kilometers. The length of the car's fuel range depends on the amount of engine oil. Below is a detailed introduction about car engine oil: 1. Overview: Engine oil, also known as engine lubricant, is called Engine-oil in English. Its density is approximately 0.91×10³ (kg/m³). It serves functions such as lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, and shock absorption. 2. Composition: Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties. Additives can compensate for and improve the shortcomings of the base oil's performance, granting it certain new properties, making them an important part of lubricating oil.
Having driven for most of my life, I find it hard to say exactly how long a car can keep going when the fuel gauge light comes on indicating low range. Last month, my old car’s light came on showing 30 km left, but by driving slowly on the highway and turning off the AC, I managed to stretch it another 40 km before refueling. Generally, it varies by car and remaining fuel—modern compact cars typically have 5 to 8 liters left when the light comes on. With a fuel consumption of 8 liters per 100 km, that theoretically means 60 to 100 km of range. But this can fluctuate wildly—in city traffic with the AC on, consumption can spike to 12 liters, possibly limiting you to just 30 km. Mountain roads or heavy loads make it worse, so I make it a habit to plan a refuel within 20 minutes of the light coming on, avoiding the risk of running dry, which is both dangerous and damaging to the car. Regularly checking fuel levels and refueling every other day in the city helps avoid unnecessary risks.
