What the Tank Holds: Petrol in a Diesel Dacia Duster
The capacity of your fuel tank is one of the earliest points to know once you have put petrol in a diesel Dacia Duster, as the share of what is in there that is now petrol depends on it. Each version of the Dacia Duster we hold data for is set out on this page alongside its tank capacity, and so are the engines it was sold with.
When it has happened, the same advice applies whatever the figure is. Ring Petrol in Diesel with the motor switched off. We will come out to you and drain it just where it stands.
The Dacia Duster fuel tank capacity on each version
Every version of the Dacia Duster in our data shares one diesel tank, holding 50 litres.
| Version | Fuel tank |
|---|---|
| Dacia Duster dCi 110 FAP 4x4 | 50 litres |
| Dacia Duster dCi 110 FAP eco 4x2 | 50 litres |
| Dacia Duster dCi 85 eco 4x2 | 50 litres |
| Dacia Duster dCi 90 eco 4x2 | 50 litres |
| Dacia Duster dCi 90 eco 4x4 | 50 litres |
What a few litres means for wrong fuel in your Dacia Duster
Wrong fuel in your Dacia Duster blends with whatever diesel is already inside the tank, and so the proportion of the fuel that's petrol hinges on how full your tank was when you filled up. Up to 50 litres fit into your tank. Topping up a nearly full one with a couple of litres of unleaded means just a small share of petrol in the whole, whereas the same amount in a nearly empty tank makes up far more of what the engine would draw.
People frequently ask how much petrol is too much. Whether the motor has run is the more helpful point to know. After it runs, the pump pulls that mixture from the tank and sends it on to the injectors.
A fuel drain is the right course whatever the share, and with a modest quantity it is usually all your Duster needs.
The engines in your diesel Duster
When you phone, it is useful to have read the badge beforehand, because the name of the version on it shows us which engine your Duster has.
Our figures list dCi badges on all diesel versions of the Duster.
Within the Duster versions we have figures for are 4x4 ones.
When you're not certain which version you drive, phone anyway then we will figure it out together.
AdBlue in a diesel Dacia Duster
Where AdBlue is concerned, your tank size counts differently. AdBlue is mainly water and does not blend with diesel, so with AdBlue in a diesel Dacia Duster, your diesel around it does nothing to thin it. Since it settles to the base of your tank, where the fuel pump draws from, even a small volume gets into your fuel lines.
AdBlue doesn't burn and gives the pump no lubrication, and as its water evaporates, the urea left over crystallises in the fuel lines and the fuel filter and attacks the metalwork around it.
On some diesel cars, AdBlue has a separate tank of its own, and its filler frequently sits next to the diesel one under the same fuel flap. Where your Duster has an AdBlue filler, its filler cap is usually blue and fits a smaller nozzle than the diesel filler.
What a fuel drain on your Dacia Duster involves
Done where your car is parked, a fuel drain on your Dacia Duster empties the entire tank, whatever size the tank is on your version. First the contaminated fuel is pumped out, then the fuel filter and fuel lines are flushed. After filling up with clean diesel, we prime your system and start the engine.
Left at home or still at the pump, your Duster gets the same job. After we finish the drain, your car is running on clean diesel and free to drive away.
AdBlue removal from a diesel Dacia Duster, explained
Clearing your tank entirely is where AdBlue removal from a diesel Dacia Duster starts, as AdBlue doesn't mix in and collects at the base instead. Where your engine has run, the lines and the filter are rinsed through too, and the filter is replaced if necessary.
What this covers is AdBlue that ended up in your diesel tank, not removing or turning off the AdBlue system on the car.
What a fuel drain on the Dacia Duster costs
There's no fixed price listed on this page, since call-outs on one model can differ quite a lot. Whether the Duster has been started or driven changes it most. After that it rests on how much got in against the fuel tank size, whether petrol or AdBlue went in, and your car's location.
Phone with those facts and we can let you know what the job will involve.
Queries on the tank and petrol in a diesel Dacia Duster
What is the fuel tank capacity of the Dacia Duster?
The same tank is fitted to every version in our figures, holding 50 litres.
Does petrol matter less in a larger tank?
A larger tank means a few litres make up less of the total, but that petrol is still in there and still gets to the pump as soon as the motor runs. Keep your Duster switched off and draining it gets all of that petrol out.
Do you cover more than one diesel Duster?
Your badge shows which of the 5 diesel versions of the Duster in the table above is yours, as we have data for each.
Wrong fuel in my Dacia Duster: what does that cover?
Petrol qualifies whatever the grade, super unleaded included, and so does AdBlue that was intended for its own separate tank. Everything other than diesel in the diesel tank is wrong fuel.
Do you come to the Dacia Duster to drain it?
We do. The car doesn't need to be moved or started, as we travel to it whether it is still on the forecourt or parked on your drive.
