Diesel gas gives more mileage (miles per gallon) than regular gasoline. You must, of course, have a vehicle that has a diesel engine because diesel fuel cannot be used in an engine that runs on regular gas! Depending on local government taxation policies, in some countries diesel is cheaper to buy than regular gas whilst in other countries it is more expensive! Diesel fuel is thicker and "stickier" than regular gas so, if a vehicle's fuel system ever needs cleaning - fuel tank, fuel lines, fuel pumps and fuel injectors - it is a more difficult and expensive job to do on a diesel vehicle.
Diesel takes longer to burn than gas so, accordingly diesel is more fuel efficient.
Diesel fuel has different chemical and physical characteristics than regular petrol. It is fractioned at a higher temperature and has a higher flashpoint.
Drain the tank, change the fuel filter, refill with diesel.
Diesel gas is a type of fuel commonly used in diesel engines. It is different from regular gasoline in terms of how it is ignited and its chemical composition. Diesel fuel is ignited by compression rather than a spark, and it contains higher energy density and lower volatility compared to gasoline.
You may be able to find a diesel additive and just use the gas in the tank.
Empty your tank out, drain the fuel lines, as the gasoline will damage your diesel engine.

Gasoline engines cannot run on diesel. Only a diesel engine can run diesel. And a diesel engine cannot run on gasoline.
If you did not start the engine no harm has been done. Drain the fuel tank, and all the fuel lines. Get as much of the gas out as possible. Fill it up with diesel and you should be ok.
