What is the density of gasoline?

[PaulMarie]

Gasoline has a density of 0.70 to 0.78g/cm. Gasoline: Gasoline is a volatile and flammable hydrocarbon mixture liquid obtained through distillation and cracking of petroleum, used as fuel. It appears as a transparent liquid, is flammable, with a distillation range of 30 to 220 degrees, mainly composed of C5 to C12 aliphatic hydrocarbons and naphthenes, along with a certain amount of aromatic hydrocarbons. Classification of gasoline: Gasoline has a high octane number (anti-knock combustion performance) and is classified into grades such as 89, 90, 92, 93, 95, 97, and 98 based on the octane number. Starting from January 2012, the gasoline grades 90, 93, and 97 were revised to 89, 92, and 95.

The density of gasoline typically ranges from 0.71 to 0.77 grams per cubic centimeter, with the exact value depending on temperature. Gasoline is a liquid but relatively light—it becomes less dense and more expansive when hot in summer, and denser when cold in winter. This affects the vehicle's weight variation. For example, when filling up a 60-liter SUV tank, the fuel weight can range from 43 to 46 kg, noticeably impacting suspension and handling due to the shift in gravitational force. It's also important to monitor the fuel level sensor for potential malfunctions. During routine maintenance, check the fuel gauge color and use a hydrometer to measure density, preventing contamination or degradation. Understanding density is highly beneficial for optimizing fuel efficiency and power output. Before long trips, it's advisable to inspect the fuel tank condition and fill it with the appropriate fuel.

The density of gasoline is approximately 0.71 to 0.77 grams per cubic centimeter, a value deeply influenced by temperature. In cold weather, the density is higher, making the fuel heavier and more substantial, while in hot weather, it's lower and lighter. I often observe people's refueling habits at gas stations. In actual driving, this affects engine performance—too heavy fuel burns slower, reducing power output, while too light fuel may evaporate too quickly, wasting fuel. During maintenance, don't forget to use a hydrometer to test density differences, ensuring the fuel system remains unclogged and the filter functions well. Choosing the right type of fuel also matters—higher-octane gasoline may have slightly higher density, burning more evenly to reduce knocking risks and extend engine life. Simply adopting a good fuel habit can save some repair costs.

The density of gasoline ranges between 0.71-0.77 grams per cubic centimeter. It decreases and becomes lighter at higher temperatures, while reversing slightly heavier in cold weather. With a lower density than water (0.71 vs 1), gasoline visibly floats on water, explaining why water accumulation in fuel tanks can cause major issues like contamination and nozzle clogging. This density variation affects fuel consumption calculations, causing minor discrepancies (a few kilometers error) when converting gallons to mileage. Older vehicle drivers may need to manually adjust driving modes for optimal efficiency.
