Gasoline in a glass jar. Gasoline (/ ˈ ɡ æ s ə l iː n /) or petrol (/ ˈ p ɛ t r ə l /) is a petrochemical product characterized as a transparent, yellowish, and flammable liquid normally used as a fuel for spark-ignited internal combustion engines.
May 10, 2024 · Gasoline, mixture of volatile, flammable liquid hydrocarbons derived from petroleum and used as fuel for internal-combustion engines. It is also used as a solvent for oils and fats. Originally a by-product of the petroleum industry, gasoline later became the preferred automobile fuel.

The octane rating on different grades of gasoline is a measurement of the fuel’s stability. Higher octane numbers mean greater stability. The greater stability indicates the gasoline’s resistance to preignition and the fuel’s ability to resist “knocking” or “pinging” during combustion. These sounds come from the air-fuel mixture detonating prematur...
The fundamental rule of car maintenance is to follow the manufacturer’s guidelines in the owner’s manual. It will show the minimum octane level for the vehicle and whether premium gas is recommended or required.
E85 is a fuel designed for “flex-fuel vehicles.” It is a blend of 51 – 83% ethanol and the balance gasoline. E85 pumps are clearly labeled at gas stations and typically have yellow nozzles. Flex-fuelvehicles usually have a yellow fuel cap. Using gasoline of any octane level in a flex-fuel vehicle is OK. However, putting E85 in a car that isn’t desi...
Diesel fuel is the common term for petroleum distillate fuel. Gasoline and diesel engines operate differently and use different types of fuel. Vehicles that use compression ignition engines use diesel fuel, while spark-ignited engines use gasoline. In general, diesel engines work more efficiently and provide greater torque, even though they generat...
Non-ethanol gas is gasoline that isn’t blended with ethanol. This type of gas isn’t sold at every filling station. Using pure gas can lead to better mileage. But increased fuel economy from using ethanol-free gas may be offset by its higher cost. Non-ethanol gasoline typically costs more than ethanol-blended varieties. Using non-ethanol gas in your...
A significant difference between grades of gasoline is the cost, and motorists often wonder why higher-grade options cost more. The additives used for boosting octane are generally more expensive to produce. At the time of this writing, the average price of regular unleaded in the United States is $3.67 per gallon, and a gallon of mid-grade costs $...
Many factors determine gasoline prices. Drivers often see higher prices in the summer driving season. Supply from refineries and demand from vacationing motorists can add up to 15 cents per gallon to gas prices in the summer months. Additionally, seasonal gasoline blends found at the pump contribute to price differences from one season to the next....
The volatile compounds of gasoline naturally degrade over time, and the combustibility of old gas decreases, even when properly stored. Gasoline can go bad from contaminants such as dirt and rust. Old gas may be refreshed to usable condition by mixing it with a high ratio of fresh gasoline. Do not use contaminated gas to power any equipment because...
Basics. Octane in depth. +Menu. Gasoline—a petroleum product. Gasoline is a fuel made from crude oil and other petroleum liquids. Gasoline is mainly used in vehicle engines. Petroleum refineries and blending facilities produce finished motor gasoline for retail sale at gasoline fueling stations.
