How to identify wrong fuel in car?
So, what happens and what can go wrong when you mistakenly fill a petrol car with diesel? Essentially, diesel fuel is denser and oilier than petrol. This can lead to several issues. Initially, it will affect the fuel filter, causing it to clog up almost immediately. As a result, your car may start to stutter and stall. Additionally, the diesel will mix with the petrol, causing the spark plugs to become fouled with soot buildup. At this stage, your car will emit excessive white smoke and eventually lose all power, coming to a complete stop.
Diesel engines are significantly more sensitive to the wrong fuel compared to petrol engines. If you mistakenly put petrol in a diesel car, it can have severe financial consequences. Diesel engines rely on the lubricating properties of diesel for crucial components like the fuel injection pump to function properly. Additionally, the rubber seals in a diesel engine are not designed to withstand the cleaning and drying properties of petrol. Identifying that petrol has been added to a diesel engine can be challenging. Common symptoms include the emission of black smoke caused by unburnt fuel, which can eventually result in a complete engine failure and prevent the car from starting.
What to do when you fill wrong fuel in vehicle?
When you realize that you’ve mistakenly filled your car with the wrong fuel, it’s crucial to take immediate action. Ideally, if you haven’t started the car yet, it’s best to proceed with the following steps. However, you may require the assistance of a mechanic at this point.
First, disconnect the main fuel line that connects the engine to the fuel tank. If possible, access the tank through the filler cap using a hose. Once you’ve reached the filler cap, attempt to syphon off as much of the wrong fuel as possible. Additionally, drain any remaining fuel through the main fuel line.
After draining out as much fuel as you can, turn the key to crank the engine a few times to remove any lingering fuel. Don’t worry, the car won’t start. The remaining fuel should drain out of the main fuel line during this process. Following this, add approximately two liters of the correct fuel and crank the engine again to flush out the lines. Once you are confident that all the incorrect fuel has been drained, you can reconnect the fuel line.
Next, refill the tank with the correct fuel and consider adding an additive to clean the injectors if you have a diesel engine.
For a petrol engine, it is necessary to change the fuel filter and clean the spark plugs. In the case of a diesel car, ensure that you open the drain plug located at the bottom of the filter to drain any remaining fuel from the filter. Afterward, prime the vehicle using a manual diesel pump and start the car.
It is important to note that these steps provide a general guideline, and it is advisable to consult a professional mechanic for assistance and further guidance in handling such situations.
