Half a tank of gas can normally run for 200 to 300 kilometers. The exact distance that can be driven depends on the car's fuel consumption per 100 kilometers and the fuel tank capacity. The fuel consumption of a car is not only related to the car itself but also greatly influenced by the driving conditions and the driver's habits. Gasoline is a volatile, flammable hydrocarbon mixture liquid obtained from petroleum through distillation or cracking, primarily used as fuel for spark-ignited internal combustion engines. It mainly consists of organic compounds obtained from crude oil distillation and various additives. The octane number of gasoline can be used to measure the anti-knock properties of a specific gasoline mixture (which can cause knocking and reduce the efficiency of reciprocating engines).

I've been driving for over a decade, and how many kilometers you can get from half a tank of gas really varies from person to person, depending on your car model and habits. My compact car consumes about 6 liters per 100 kilometers, with a 55-liter fuel tank, so half a tank is 27.5 liters, theoretically capable of running 450 kilometers. But in reality, in city traffic with congestion, it might only go a little over 300 kilometers, while on the highway, it can exceed 400. The reasons? Traffic jams waste fuel, prolonged use of air conditioning, and underinflated tires all reduce mileage. I've also noticed that aggressive braking and acceleration spike fuel consumption, while regular oil changes help maintain stable fuel efficiency. My advice: record your mileage after your next fill-up and gradually calculate the average—don't expect instant results.

As an efficiency-focused individual, I must say there's no absolute standard for half-tank mileage. The key lies in fuel consumption: check your car's manual for the liters per 100 km figure (e.g., 10L/100km). With a 60L tank, 30L (half tank) would theoretically cover ~300km. However, driving habits significantly impact this: gentle driving saves 20% fuel; hilly terrain increases consumption; AC use in summer reduces range. My approach: maintain steady speeds of 70-90 km/h, minimize cargo load; perform regular maintenance ensuring clean air filters and proper spark plugs. Actual range typically falls between 200-350km – don't panic. Developing a mileage log habit improves estimation accuracy.

As a regular car owner, I also struggled with how far half a tank of gas could take me when I first bought my car. My experience is that it varies greatly: my compact car once went 280 km on half a tank, but now with AC on in hot weather, it might be less. My friend's SUV is even more fuel-thirsty, covering only slightly over half that distance. It depends on the model, road conditions, and driving habits—city crawling reduces range, while highway driving saves fuel. Best to use an app to track mileage per fill-up and calculate averages. Bottom line: don't fixate on numbers, just find a gas station when running low.
