What is the standard density table for gasoline?
3 Answers
90-octane gasoline has an average density of 0.72g/ml; 93-octane gasoline has a density of 0.725g/ml; 97-octane gasoline has a density of 0.737g/ml; 0# diesel is 0.84g. Below is relevant information about gasoline: 1. Properties: It appears as a transparent liquid, is flammable, and primarily consists of C4 to C12 aliphatic and cyclic hydrocarbons, with small amounts of aromatic hydrocarbons and sulfides. Based on the research octane number, it is classified into three grades: 90, 93, and 97. 2. Functions: Gasoline has a high octane number and excellent anti-knock properties, making it suitable for high-compression-ratio carburetor-type gasoline engines, which can enhance engine power and reduce fuel consumption. It exhibits good volatility and combustibility, ensuring smooth engine operation, complete combustion, and minimal carbon deposits. It also has good stability, resisting early oxidation and deterioration during storage and transportation, and is non-corrosive to engine components and fuel storage containers.
I've been running this auto repair shop for over twenty years, dealing with gasoline density on a daily basis. The standard density chart typically refers to measurements taken at 15°C, with regular unleaded gasoline ranging from about 0.72 to 0.77 grams per cubic centimeter. This value isn't fixed—winter densities can climb to 0.78 when it's cold, while summer heat may drop it to around 0.73, so temperature significantly impacts refueling. Higher density means thicker fuel, potentially giving more mileage per liter, but excessive viscosity can clog injectors or cause cold-start issues. When checking customers' vehicles with my simple hydrometer, abnormally low density often indicates water contamination or adulterated fuel. It's crucial to monitor these readings periodically to prevent engine failures compromising safety, especially before long trips—always verify fuel quality stability beforehand.
I often tinker with car modifications and have been studying fuel properties for a long time. The standard gasoline density table shows a range of 0.71 to 0.78 grams per milliliter at 15°C, with regular unleaded gasoline around 0.74. Higher density means more concentrated fuel, which can improve acceleration but may increase fuel consumption; lower density has the opposite effect. I've personally tested density in summer and found that a 10°C temperature increase reduces density by about 0.03, so refueling during cooler hours can save money. Fuel brands also affect these values—for example, premium gasoline has a slightly higher density of 0.77, but regular fuel is sufficient for family cars. If you want to measure it yourself, just buy an inexpensive densitometer or check the label data, and avoid tampering with the fuel to prevent damaging your car.
