Tank Sizes and Petrol in a Diesel Peugeot 207
The size of the fuel tank is among the earliest points worth knowing once you have got petrol in a diesel Peugeot 207, since the share of what is in there that's currently petrol hinges on it. Our guide gives the tank size on every version of the Peugeot 207 we hold figures for, plus the engines it came with.
When it has happened, the same guidance applies whatever the figure is. With your engine left off, phone Petrol in Diesel and your car will be emptied where it sits.

Does a little volume of wrong fuel in your Peugeot 207 matter?
How full the tank was when you refuelled determines the proportion of petrol, because wrong fuel in your Peugeot 207 mixes with whatever diesel was still there. When a few litres of unleaded are put into a tank running close to empty, they make up a much bigger share of what the engine would take in. Added to an almost full tank of up to 50 litres, the same volume is just a small share of the total.
Drivers often wonder how much petrol is too much. Whether your engine has run is the more helpful point to find out. Once it runs, your pump pulls the mixture from your tank and pushes it on to your injectors.
A drain is the right option whatever the share, and with a small amount it's normally all your 207 needs.
Diesel 207 engines and their badges
Before you phone, it is worth reading the version name on the badge, because it shows us which engine your 207 has.
Across the diesel 207 versions in our data, the badges read HDi.
The figures also include SW versions of the 207.
Being unsure which version you have doesn't need to stop you. Call anyway, then we'll figure it out with you.
What happens with AdBlue in a diesel Peugeot 207
With AdBlue, fuel tank size plays out differently. The fuel pump takes its fuel from the bottom of the tank, and that is where AdBlue sinks, so even a tiny quantity reaches the fuel line. If you have got AdBlue in a diesel Peugeot 207, the diesel surrounding it does not dilute it, because AdBlue is largely water and does not mix with it.
Nothing in AdBlue ignites, and your pump gets no protection from it. Once its water dries out, urea is left in your lines and the filter as crystals, and the metalwork next to it corrodes.
A second tank with its own filler holds the AdBlue on certain diesel vehicles, commonly alongside the diesel filler under the same fuel flap. On any 207 with an AdBlue filler, a blue cap normally shows it, and that cap takes a narrower nozzle than the diesel one.
A fuel drain on your Peugeot 207, step by step
Done where the vehicle is standing, a fuel drain on your Peugeot 207 clears the entire tank, whatever size the tank is on your version. Pumping out the tainted fuel comes first, then a flush of the lines and the fuel filter. After that we top up with fresh diesel, prime the system and start the motor.
It makes no difference whether your 207 is sitting at the station forecourt or parked on your driveway. Clean diesel is what it runs on once the drain is finished, and so you can drive it away.
How AdBlue removal from a diesel Peugeot 207 works
AdBlue removal from a diesel Peugeot 207 starts with clearing the tank fully, since AdBlue gathers at the base instead of blending in. An engine that has been started means flushing your filter and lines through as well, plus replacing the fuel filter if it needs it.
Taking out or switching off the AdBlue system on the car isn't what this is about. It's about AdBlue that has gone into your diesel tank.
How the quote of a fuel drain on the Peugeot 207 is set
There's no fixed price published on this page, since call-outs on one model can differ quite a lot. Whether the 207 has been started or driven changes it most. After that it rests on how much was put in compared with your tank size, whether petrol or AdBlue went in, and your car's location.
With those details, we can explain what the job will need when you ring.
Your tank queries on petrol in a diesel Peugeot 207
What does the Peugeot 207 fuel tank capacity come to?
50 litres, with every version we hold data for sharing the same tank.
Is petrol less of a problem in a bigger tank?
A larger tank means a few litres form less of the whole, but that petrol is still in there and still gets to your pump as soon as the engine runs. Keep your 207 switched off and draining it gets all of the petrol out.
How many diesel versions of the 207 do you cover?
Our data include 6 diesel versions of the 207, all listed in the table above, so you can spot yours there using the name shown on its badge.
Which fuels, other than diesel, would be wrong fuel in my Peugeot 207?
Just diesel belongs in the diesel tank. Petrol of every grade, super unleaded too, is wrong fuel, and so is AdBlue, which belongs in a tank of its own.
Wherever the Peugeot 207 is, can you drain it?
Yes, wherever it is. Sitting at home or still at the pump, your car stays where it is and is not started, because we come to it.
