Petrol in a Diesel Mercedes Vaneo? Start With the Tank
How much petrol there currently is in the blend rests on the tank, so its size is worth checking early if you have put petrol in a diesel Mercedes Vaneo. We set out the tank on every version of the Mercedes Vaneo which our figures cover on this page, together with the motors it was sold with.
No matter what the number is, there is a single thing to do after the mistake. Keep the engine off and call Petrol in Diesel, and we will come out to drain the car where it is.
How every version stacks up on Mercedes Vaneo fuel tank capacity
54 litres is what the fuel tank takes on every version of the Mercedes Vaneo we have data for, as they all share the same fuel tank.
Does a small quantity of wrong fuel in your Mercedes Vaneo count?
How full your tank was when you filled up determines the share of petrol, as wrong fuel in your Mercedes Vaneo mixes with whatever diesel was already there. When a few litres of unleaded go into a tank sitting near empty, they make up a much bigger part of what the motor would draw. Added to an almost full tank of up to 54 litres, the same amount is just a minor share of the total.
Frequently, drivers want to know at what point the petrol becomes too much. Starting your engine is what carries the mixture out of the tank and through the pump and the injectors, so the more useful point to know is whether it has run.
With a small amount, a fuel drain is normally all your Vaneo needs, and whatever the proportion, having it drained is the right course.
The engines on your diesel Vaneo
The version name on your badge tells us which motor your Vaneo has, so it is worth reading before you phone.
Among the diesel Vaneo versions in our data, the badges read CDI.
Whichever version it is, the motor is 1.7 litres.
If you're not sure which version you own, phone anyway then we will work it out with you.
When there's AdBlue in a diesel Mercedes Vaneo
Where AdBlue is concerned, the tank size counts differently. If you have AdBlue in a diesel Mercedes Vaneo, your diesel surrounding it doesn't weaken it, since AdBlue is mostly water and doesn't mix with diesel. It settles to the base of the tank, which is where the fuel pump pulls from, and so even a tiny volume gets into your fuel line.
Nothing in AdBlue burns, and the pump gets no lubrication from it. Once its water evaporates, urea is left in the fuel lines and your filter as crystals, and the metal next to it is eaten into.
A separate tank with a dedicated filler holds the AdBlue on certain diesel vehicles, commonly alongside the diesel filler under the same flap. On any Vaneo with an AdBlue filler, a blue cap normally shows it, and that cap takes a narrower nozzle than the diesel one.
What a fuel drain on your Mercedes Vaneo involves
Whatever size your tank is on your version, a fuel drain on your Mercedes Vaneo clears the lot, right where your car is sitting. Drawing out the tainted fuel comes first, followed by a flush of your lines and the filter. After that we refill with clean diesel, prime your system and fire up the engine.
Left at home or still at the pump, your Vaneo receives the same job. When the drain is done it is running on fresh diesel and you can take it away.
AdBlue removal from a diesel Mercedes Vaneo
Draining your tank completely is how AdBlue removal from a diesel Mercedes Vaneo starts, since AdBlue does not mix in and settles at the base instead. Where the motor has run, your lines and your filter are cleaned through as well, and the fuel filter is changed if necessary.
This covers AdBlue that has gone into the diesel tank. It is not taking out or turning off the AdBlue system on your car.
Pricing a fuel drain on the Mercedes Vaneo
Two jobs on the same model can be rather different, so we don't publish a fixed price. Whether the Vaneo has been run or driven changes it most. After that it rests on how much was put in compared with the tank size, whether petrol or AdBlue went in, and your car's location.
Phone with those details and we can explain what this job will take.
Tank queries about petrol in a diesel Mercedes Vaneo
What does the Mercedes Vaneo fuel tank capacity come to?
Each version we hold data for shares one tank, and it takes 54 litres.
Does petrol matter less in a bigger tank?
A bigger tank means a couple of litres form less of the total, yet that petrol is still in there and still reaches your pump once your engine runs. With your Vaneo switched off, a fuel drain removes all of it.
Which fuels, other than diesel, would be wrong fuel in my Mercedes Vaneo?
Petrol qualifies whatever the grade, super unleaded too, and so does AdBlue that was intended for its own separate tank. Everything other than diesel in the diesel tank is wrong fuel.
Can you drain the Mercedes Vaneo wherever it is?
Yes, wherever it is. Sitting at home or still at the pumps, the car remains put and is not started, because we travel to it.
