What the Tank Holds: Petrol in a Diesel Citroen Nemo
If you have got petrol in a diesel Citroen Nemo, the capacity of its tank is among the first points to know, as it determines how much of what is in there is currently petrol. Our page sets out the tank size for each version of the Citroen Nemo we keep figures for, together with the engines it was offered with.
Whatever the size, the guidance is unchanged once it has occurred. With the motor left off, call Petrol in Diesel and the car can be emptied where it stands.
Version by version: Citroen Nemo fuel tank capacity
On the Citroen Nemo, the fuel tank takes 45 litres, and it's the same on each version we have figures for.
| Version | Fuel tank |
|---|---|
| Citroen Nemo HDi 70 | 45 litres |
| Citroen Nemo HDI 75 | 45 litres |
A couple of litres of wrong fuel in your Citroen Nemo, and what they mean
How full your tank was when you filled up sets the share of petrol, as wrong fuel in your Citroen Nemo blends with whatever diesel was already there. When a couple of litres of unleaded go into a tank sitting near empty, they make up a much bigger part of what the motor would take in. Added to a nearly full tank of up to 45 litres, the same amount is only a small share of the total.
Drivers often ask how much petrol is too much. Starting the motor is what moves that mixture from the tank and through your pump and the injectors, so the more helpful point to know is if it has run.
Whatever the share, the right course is to get it drained, and with a modest amount a fuel drain is usually all your Nemo needs.
Which engines the diesel Nemo was sold with
Before you phone, it is worth noting the version name on the badge, because it tells us which engine your Nemo has.
The badges on the diesel versions of the Nemo within our figures are HDi.
Call anyway if you are not certain which version you own, and we will work it out with you.
When there's AdBlue in a diesel Citroen Nemo
AdBlue alters what the capacity of the tank means. If you have AdBlue in a diesel Citroen Nemo, your diesel surrounding it does not dilute it, as AdBlue is mainly water and doesn't mix with diesel. It settles to the base of the tank, which is where the fuel pump pulls from, so even a tiny volume gets into your fuel lines.
AdBlue gives the pump no lubrication and won't burn. Its water evaporates as it sits, leaving urea that crystallises in your filter and the lines, where it attacks the metal it touches.
The filler neck for AdBlue, on diesel vehicles that have it, often shares a fuel flap with the diesel one and feeds a second tank. If your Nemo has one, the AdBlue filler cap is normally blue and fits a narrower nozzle than the diesel one.
How a fuel drain on your Citroen Nemo works
The entire tank is cleared in a fuel drain on your Citroen Nemo, however large it is in your version, without the car being moved from where it sits. We pump the tainted fuel out, flush the lines and the fuel filter, and fill up again with clean diesel ahead of priming the system and starting the motor.
It does not matter whether your Nemo is sitting on the forecourt or left on your driveway. Fresh diesel is what it runs on when this drain is finished, so you can take it away.
AdBlue removal from a diesel Citroen Nemo
Draining the tank totally is how AdBlue removal from a diesel Citroen Nemo starts, as AdBlue does not blend in and collects at the bottom instead. An engine that has been run means purging your filter and lines through as well, and replacing the fuel filter if needed.
What this covers is AdBlue that ended up in the diesel tank, not taking out or turning off the AdBlue system on the vehicle.
The price of a fuel drain on the Citroen Nemo
The same model can mean quite different call-outs, which is why we do not list a fixed price. What affects it most is whether the Nemo has been run or driven, and beyond that how much went in against the capacity of the tank, whether it was petrol or AdBlue, and where your car is now.
Those details are what we need to tell you what the work involves. Phone with them to hand.
Your tank questions on petrol in a diesel Citroen Nemo
What's the fuel tank capacity of the Citroen Nemo?
45 litres, with every version we have data for using the same tank.
Does a bigger tank make petrol less of a worry?
Less of the whole is petrol if a few litres go into a bigger tank, yet it's still there, and running the motor still carries it to the pump. A drain removes all of it while your Nemo is switched off.
Diesel versions of the Nemo: how many do you list?
There are 2 diesel Nemo versions in our figures, and the model name on the badge tells you which row of the table above is yours.
Is it wrong fuel in my Citroen Nemo if it's not diesel?
Petrol qualifies whatever the type, super unleaded included, and so does AdBlue that was meant for its own dedicated tank. Everything other than diesel in your diesel tank is wrong fuel.
Can you drain the Citroen Nemo where it is?
Yes, wherever it is. Sitting at home or still at the pump, the vehicle stays where it is and isn't started, since we travel to it.
