What is the general density of gasoline?
2 Answers
Gasoline density generally ranges from 0.70 to 0.78 grams per cubic centimeter. Concept of gasoline: Gasoline is a volatile and flammable hydrocarbon mixture liquid obtained from petroleum through distillation and cracking, used as fuel. It appears as a transparent liquid, is flammable, with a distillation range of 30 to 220 degrees Celsius. The main components are C5 to C12 aliphatic hydrocarbons and cycloalkanes, along with a certain amount of aromatic hydrocarbons. 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 octane ratings. Starting from January 2012, the gasoline grades 90, 93, and 97 were revised to 89, 92, and 95. Selection of gasoline: The type of gasoline a vehicle uses is closely related to its engine matching. Higher compression ratios result in greater power and efficiency but correspondingly lower stability, thus requiring gasoline with better anti-knock properties.
As an ordinary person who drives frequently, I always notice the issue of gasoline density every time I refuel. Generally, the density ranges from about 0.7 to 0.78 grams per cubic centimeter, which has a significant impact on daily driving. For example, in summer when temperatures are high, the density decreases slightly, meaning the same volume of fuel actually contains less energy, resulting in shorter driving distances. I've noticed during city commuting that choosing gas stations with stable density can help save unnecessary expenses. Density differences also affect fuel consumption calculations, so I make it a habit to use a mobile app to record fuel amounts and mileage to avoid misinterpreting the fuel gauge. During seasons with large temperature fluctuations, such as the transition from winter to spring, density variations are more noticeable, so it's best to drive a short distance after refueling to verify the gauge readings. A handy tip is to refuel in the morning when temperatures are lower and density is slightly higher, allowing you to get more energy. In short, understanding density helps save both hassle and fuel, and I recommend car owners pay attention to gasoline label information.
