Are a group of hydrocarbon - based substances derived from crude oil through various refining processes. Crude oil, a naturally occurring liquid found beneath the Earth's surface, consists of a mixture of hydrocarbons, which are organic compounds made up of hydrogen and carbon atoms. Refining processes separate these hydrocarbons into different components based on their molecular weight and properties.

Gasoline is a light liquid fuel primarily used in internal combustion engines for automobiles, motorcycles, and small aircraft. It's one of the most widely used petroleum products due to its efficiency and convenience.

Diesel fuel is heavier and less volatile than gasoline. It's commonly used in diesel engines found in trucks, buses, trains, ships, and some cars. Diesel engines are known for their fuel efficiency and torque output.

Jet fuel, also known as aviation turbine fuel (ATF), is a specialized type of kerosene-based fuel specifically designed for use in aircraft jet engines. It has strict specifications to ensure safe and efficient operation of aircraft.

Heating oil, also known as fuel oil, is used for heating homes and buildings. It's similar to diesel fuel but is often dyed red for tax purposes and may have additives to improve its performance in heating systems.

Liquefied Petroleum Gas 

consists mainly of propane and butane and is commonly used as a fuel for heating appliances, cooking, and in some vehicles. It's stored under pressure as a liquid but turns into a gas when released from its container.

Kerosene is a light petroleum distillate commonly used as a fuel for lamps, heaters, and stoves. It's also used as a solvent and as a base material for jet fuel.

Heavy Fuel Oil is a dense, viscous liquid used as fuel in industrial boilers, power plants, and large ships. It's cheaper than diesel but produces more pollutants when burned.

Asphalt, also known as bitumen, is a sticky, black, and highly viscous liquid or semi-solid form of petroleum used in road construction, waterproofing, and roofing.
