Petrol in a Diesel Renault Laguna: What the Tank Holds
How much petrol there currently is in that blend hinges on the tank, so its capacity is worth finding out early on if you've put petrol in a diesel Renault Laguna. Each version of the Renault Laguna we have figures for is on this page with its tank size, and so are the engines it came with.
Whatever the figure, the advice is no different now that it has occurred. With the motor kept off, phone Petrol in Diesel and the vehicle can be drained where it is.

What a couple of litres amounts to for wrong fuel in your Renault Laguna
Wrong fuel in your Renault Laguna blends with whatever diesel is still in the tank, and so the share of it that is petrol hinges on how full the tank was when you refuelled. How much petrol goes to the motor depends a lot on the amount inside your tank. It takes up to 70 litres, and in a nearly full one a couple of litres stay a minor part of the total, but in a tank sitting close to empty the same few litres make up a much greater part.
Frequently, people want to know at what point the petrol gets to be too much. It is more useful to find out whether the motor has run, since a running engine is what moves the mixture from the tank and through your pump and the injectors.
A fuel drain is the safe option no matter what the share, and with a small quantity it's normally all your Laguna needs.
Which engines your diesel Laguna came with
The motor in your Laguna shows in the version name on the badge. Note it before you phone.
Across all diesel Laguna versions in our data, the badges read dCi and DTI.
The dCi badge shows up on more of them than any other, while the Laguna 1.9 dTi is a version that has the DTI badge instead.
The engines range from 1.5 litres in the Laguna 1.5 dCi to 3.0 litres on the Laguna Coupe 3.0 dCi V6 FAP.
There are Coupe Laguna versions in the data as well.
Not knowing which version you drive doesn't need to stop you. Call all the same, then we'll figure it out with you.
When there is AdBlue in a diesel Renault Laguna
Fuel tank size plays out differently with AdBlue. If you have got AdBlue in a diesel Renault Laguna, your diesel surrounding it does not weaken it, because AdBlue is largely water and does not mix with diesel. It settles to the bottom of your tank, which is where the fuel pump draws from, and so even a small volume gets into your fuel lines.
Nothing in AdBlue ignites, and the pump gets no lubrication from it. When its water dries out, urea is left in your lines and your filter as crystals, and the metalwork next to it is eaten into.
On certain diesel vehicles, AdBlue has a separate tank of its own, and its filler commonly is alongside the diesel filler under the same fuel flap. On any Laguna with an AdBlue filler, a blue cap usually marks it, and that cap accepts a narrower nozzle than the diesel one.
Fuel drain on your Renault Laguna
Whatever size the tank is on your version, a fuel drain on your Renault Laguna empties all of that, right where your car is sitting. Fresh diesel is put in after the contaminated fuel gets pumped out and the lines and the fuel filter are cleaned, and then your system is primed and your engine started.
Parked at home or still at the pump, your Laguna receives the same drain. When the drain is complete it is running on fresh diesel and you can take it away.
AdBlue removal from a diesel Renault Laguna
With AdBlue sitting at the bottom of your tank rather than blended in, AdBlue removal from a diesel Renault Laguna starts by draining your tank completely. Where the engine has run, the lines and your filter are purged through as well, and your fuel filter is replaced if necessary.
What this covers is AdBlue that ended up in your diesel tank, not taking out or disabling the AdBlue system on your car.
How the price of a fuel drain on the Renault Laguna is worked out
There is no fixed price listed here, because jobs on one model can vary quite a lot. How much was put in compared with the size of the tank, petrol or AdBlue, and where the car is now all count, yet whether the Laguna has been driven or only started affects it most.
Phone with those facts and we can explain what the job will take.
Queries on your tank and petrol in a diesel Renault Laguna
What does the Renault Laguna fuel tank capacity come to?
From 66 to 70 litres according to the version, and every version is listed in the table above.
Does petrol matter less in a larger tank?
A bigger tank means a couple of litres make up less of the whole, yet the petrol is still there and still gets to the pump once the engine runs. A fuel drain removes all of that as long as your Laguna stays switched off.
How many diesel versions of the Laguna do you list?
We keep figures for 21 diesel versions of the Laguna, and you can spot yours in the table above from the model name on its badge.
Wrong fuel in my Renault Laguna: what does that include?
It means everything put into the diesel tank that is not diesel, so petrol of any grade, including super unleaded, or AdBlue, which has its own dedicated tank.
Will you drain the Renault Laguna where it stands?
There's no reason to shift or start the vehicle. Whether it's parked on your drive or still on the station forecourt, we travel to it.
