Misfuelling refers to the unintentional act of filling a vehicle's tank with the wrong type of fuel, a common mistake with potentially severe consequences for the engine. For learners preparing for the German driving theory test, it's important to understand the preventive measures and immediate actions required if this situation arises. Knowing your vehicle's correct fuel type and exercising caution at the pump are fundamental aspects of responsible driving. This knowledge not only protects your vehicle but also reinforces safe operational practices relevant to German road standards.
Falschtanken
Misfuelling occurs when a driver accidentally puts the incorrect type of fuel into their vehicle, such as petrol into a diesel car or vice-versa.

See how Misfuelling appears in realistic driving situations relevant to Germany. These examples explain correct behaviour, safety implications, and how Misfuelling connects to German driving theory exam questions.
You are driving a rented diesel car in Germany and pull into a petrol station. You are used to filling your personal petrol car and absent-mindedly grab the green petrol nozzle.
As soon as you realize your mistake, stop refuelling immediately. Do not start the engine or even turn the ignition on. Inform the petrol station staff and call a German roadside assistance service like ADAC.
Starting the engine would circulate the petrol through the diesel engine, causing immediate and severe damage to the fuel pump and injectors. Prompt action to prevent fuel circulation is crucial to minimise repair costs and potential engine failure.
You've just bought a used car in Germany and are unsure if it runs on diesel or petrol. You're at the fuel station and about to choose a pump.
Before inserting any nozzle, check the fuel flap, the car's manual, or a sticker on the dashboard for the correct fuel type. If still unsure, ask for assistance or look up the car's specifications online.
Knowing the correct fuel type is the primary defence against misfuelling. Taking a moment to verify prevents a costly and damaging mistake, ensuring the vehicle operates as intended and avoiding expensive repairs that could have been easily prevented.
After a long day, you are tired and mistakenly put petrol into your diesel vehicle at a German fuel station, but you only put in a small amount before realizing. You've closed the fuel cap and are about to get back into the car.
Even if only a small amount of incorrect fuel has been added, do not start the engine. Leave the car where it is, contact roadside assistance, and arrange for the tank to be drained and flushed.
Even a small quantity of incorrect fuel can be enough to cause damage once it enters the fuel system. The priority is to prevent any circulation of the misfuelled mixture, as even minor exposure can lead to lubrication issues in diesel engines.
You've arrived at a petrol station in Germany and see multiple fuel options, including 'Super E5', 'Super E10', and 'Diesel'. Your car requires 'Super E5' petrol.
Carefully select the 'Super E5' pump, confirming the label and nozzle colour match your vehicle's requirements before starting to refuel. Double-check that you're not selecting a diesel pump.
Paying close attention to specific fuel grades and their corresponding pump labels at German petrol stations is essential. Choosing the wrong grade, like E10 for a car not compatible with it, or accidentally selecting diesel, can cause engine problems or misfuelling damage.
You borrow a friend's car for a trip across Germany. When it's time to refuel, you assume it takes the same fuel as your own car without checking.
Before refuelling, always confirm the correct fuel type for a borrowed vehicle by checking the fuel cap, owner's manual, or directly asking the owner. Do not make assumptions.
Vehicles differ in fuel requirements. Assuming the fuel type can easily lead to misfuelling, causing damage to someone else's property and potentially incurring significant repair costs that you would be liable for.

Misfuelling, known as Falschtanken in German, is the act of filling a vehicle's fuel tank with an incompatible fuel type. This typically involves putting petrol (Benzin) into a diesel (Diesel) vehicle, or less commonly, diesel into a petrol vehicle. While seemingly a minor oversight, the chemical properties and combustion mechanisms of these fuels are vastly different, making misfuelling a serious and potentially very costly error for any driver, including those on German roads.
If you realise you have put the wrong fuel into your vehicle, it is critical to act immediately to minimise damage:
The most frequent misfuelling mistake is putting petrol into a diesel car. Diesel pump nozzles are usually larger than petrol nozzles, making it harder to put diesel into a petrol car. However, petrol nozzles easily fit into diesel car fuel inlets. Modern diesel engines, especially those in Germany, operate with high precision and pressure. Petrol acts as a solvent, stripping away the lubricating properties of diesel and causing severe wear and tear to the fuel pump and injectors very quickly. This can lead to costly repairs or even complete engine failure.
Conversely, putting diesel into a petrol car is less common but still damaging. Diesel is thicker and has a higher ignition temperature, which can clog fuel lines, foul spark plugs, and prevent the engine from running efficiently or at all. Prolonged use can damage the catalytic converter and engine components.
Prevention is key. Always take a moment to double-check the fuel type before you begin refuelling. Key tips include:

Misfuelling, or Falschtanken, in German driving theory refers to accidentally filling a vehicle with the wrong type of fuel, most commonly putting petrol into a diesel engine or vice versa. It's a critical error with serious implications for engine health and road safety.
The most crucial step is to absolutely NOT start the engine or even turn the ignition on. Alert the petrol station staff, then contact a professional German roadside assistance service, such as ADAC, to arrange for the fuel tank to be drained and the system flushed.
The consequences can be severe, ranging from damaged fuel pumps and injectors to complete engine failure, especially if a diesel engine is run on petrol. Repairs can be very expensive, and such damage might not be covered by standard vehicle insurance due to driver error.
Always double-check your vehicle's specific fuel type (e.g., Diesel, Super E5, Super E10) by looking at the fuel flap or manual. Visually confirm the label on the pump nozzle matches your requirement before you begin refuelling, and avoid distractions.
While some comprehensive (Vollkasko) insurance policies might cover misfuelling damage, it's not universally guaranteed. Often, it's considered an operational error and may be excluded or subject to specific conditions. Always check your individual insurance policy terms and conditions.
