How many kilograms is one liter of 95-octane gasoline equal to?

95-octane gasoline is equal to 1.5 kilograms per liter. Gasoline: Gasoline is a volatile, 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°C to 220°C. Its main components are C5～C12 aliphatic hydrocarbons and naphthenic hydrocarbons, along with a certain amount of aromatic hydrocarbons. Gasoline has a high octane number (anti-knock combustion performance) and is classified into different grades based on octane numbers, such as 89, 90, 92, 93, 95, 97, and 98. Starting from January 2012, the gasoline grades 90, 93, and 97 were revised to 89, 92, and 95, respectively. Physical and chemical properties: At room temperature, gasoline is a colorless to light yellow, easily flowing liquid, hardly soluble in water, and flammable, with a distillation range of 30°C to 205°C. It explodes upon contact with fire when the air contains 74 to 123 grams per cubic meter. The calorific value of gasoline is approximately 44,000 kJ/kg (the calorific value of fuel refers to the heat produced by the complete combustion of 1 kg of fuel).
To be honest, I often help friends repair cars and tinker with engines. From what I recall, the density of 95-octane gasoline is roughly in the range of 0.72 to 0.77 grams per milliliter, averaging around 0.75 grams per milliliter. One liter equals 1000 milliliters, so the weight is approximately 0.75 kilograms. Converting to Chinese jin (where 1 jin equals 0.5 kilograms), that comes out to about 1.5 jin. However, the actual weight can vary with temperature—colder weather increases density, possibly nearing 1.55 jin, while hotter weather makes it slightly lighter. By the way, the number 95 indicates a higher octane rating, which means better anti-knock performance, but the weight is practically the same as 92-octane fuel and doesn’t affect fuel consumption calculations. Also, remember to use sturdy fuel tanks to prevent corrosion and leaks, which is crucial for maintaining older vehicles.
