Putting petrol in diesel or diesel in petrol
What is misfueling?
Misfuelling means putting wrong fuel in the car, whether it is diesel in a petrol car or petrol in a diesel. Many people mistakenly fill their cars with wrong fuel every day. Here’s how can you prevent wrong fuelling and what are its types.
Petrol in diesel car
Petrol nozzles can comfortably fit into the new diesel filter necks, making the mistake of putting petrol into a diesel tank more common. Added to that is, putting petrol into a diesel tank causes more damage.
Another important thing to keep in mind is the more petrol that gets pumped through your diesel fuel system, the more damage it will do.
HDi diesel engines are more likely to get damaged from misfuelling. If there’s a considerable damage, you could be looking at new injectors, fuel pumps, filters, pipes, fuel tank or even a whole new replacement engine. That’s weird, isn’t it?
Diesel in petrol engine
The diesel pump nozzle is larger than the petrol filler necks, so diesel in petrol fuelling is far less common than petrol being put in a diesel car. Plus, the outcome of putting diesel in a petrol engine are generally not as acute as putting petrol in diesel car.
Diesel and petrol are instigated by two totally different methods. To ignite, diesel has to be compressed but on the other hand petrol is ignited when the spark is generated by the spark plugs. When diesel is placed inside a petrol engine, the most frequent result is the chocking up of spark plugs and fuel system and ultimately the engine won’t start.
Diesel in petrol engine can be a real pain. But all in all, not as dangerous as petrol in diesel engine.
How to prevent wrong fuelling?
Looking for a best way to avoid misfuelling? Well the clear-cut answer is always fill the tank with the correct fuel.
While no one’s perfect and it’s nearly impossible to avoid innocent mistakes from time to time, yet there are a few things we can keep in mind to reduce the risk of misfuelling:
- Don’t just depend on the colour of the hose or nozzle before filling up the tank. Properly read the trigger pump’s label and the fuel grade indicator.
- If you’ve just got a new car with a different fuel engine to your previous car, leave yourself reminders to minimize the risk of wrong fuelling.
- Cut out distractions and focus before getting into fuelling station. For the time it takes to refuel, put your phone away and give your whole attention to the task in hand.
- Avoid refuelling when you’re in a hurry, hungry or stressed. We are more likely to slip up when we are in hurry or stress.
What to do if you have placed incorrect fuel in your car?
The first and foremost thing you have to do right after placing wrong fuel in your car is don’t turn on the ignition or start the engine. If it happens, you might have to get the whole Selective Catalytic Reduction and AdBlue injection system replaced.
If you have placed incorrect fuel in your car, don’t start it, just stop right there and call wrong fuelling service for draining out. That’s the only option you have got.
