Gasoline and diesel engines are designed to work differently. Thus, putting gasoline in a diesel engine can create some serious issues. However, since a gasoline nozzle can fit into diesel engine vehicles easily, sometimes people end up putting the wrong fuel accidentally. When this happens, it’s important that you don’t drive your car, or else you might up doing long term damage which might make it difficult to sell your car in Abu Dhabi.

Gasoline And Diesel Engines Work Differently

While both gasoline and diesel engines turn fuel into mechanical energy, the way the combust chemical energy is different. Moreover, even though both gasoline and diesel are derived from crude oil, diesel is heavier. Thus, it doesn’t require a spark plug to ignite like gasoline does, and uses air compression instead. A gasoline engine, on the other hand, mixes the fuel with air and compresses it by pistons. Then, it’s ignited by spark plugs.

What Happens When You Put Gasoline In A Diesel Engine?

Since the way the two engines operate and the properties of the two fuels are so different, swapping them is actually a perfect recipe for disaster. Of course, an experienced driver will never do this purposely. However, if this accidentally happens and you can’t recall if you have put the wrong fuel in the tank, there are some telltale signs to look for such as difficulty starting the vehicle, smoke emitting from the exhaust pipe, and acceleration making the engine noisier.

The minimum temperature needed to ignite fuel in a diesel vehicle engine is 52 degrees Celsius. In a gasoline engine, it’s -43 degrees Celsius. Thus if you put gasoline in a diesel engine, it will have a pretty hard time igniting. So, it will build up in the cylinders.

 Another problem is that diesel injectors are made to spray diesel into a fine mist. However, this cannot be done with gasoline as it’s not as dense as diesel. Moreover, the gasoline injectors operate at higher pressures than gasoline injectors. This means putting the wrong fuel can actually rupture them. The injectors need to be lubricated, something that gasoline can’t do. Thus when it flows through a diesel engine, it can cause various components such as delivery system, fuel pump, and valve train to fail in the long run. This also increases the risk of metal fillings going into the cylinder.

What To Do When You Realize You Have Put The Wrong Fuel

First of all, congratulate yourself. Catching the problem early on can help you save your car from severe internal damage. When you realize the car has the wrong fuel, stop it immediately. Do not drive in this state, as it will just make things messy. Next, get the services of a tow truck to move your vehicle to a local dealership or auto mechanic. The professionals will completely drain your fuel tank and flush out the fuel system. Do you want to upgrade your ride or sell your car in Abu Dhabi?
