Tank Sizes and Petrol in a Diesel Renault Fluence
Anyone who has got petrol in a diesel Renault Fluence needs to know the size of its tank early, since that settles how much of what is in there is currently petrol. Every version of the Renault Fluence we have figures for is set out on this page with its fuel tank capacity, and the same goes for the engines it came with.
After it has happened, the same guidance applies whatever the size is. Call Petrol in Diesel with the motor switched off. We will come out to you and empty it right where it stands.
Renault Fluence fuel tank capacity, by version
On the Renault Fluence, the fuel tank holds 60 litres, and it is the same on every version we have data for.
| Version | Fuel tank |
|---|---|
| Renault Fluence dCi 110 FAP | 60 litres |
| Renault Fluence dCi 90 FAP | 60 litres |
A couple of litres of wrong fuel in your Renault Fluence, and what they mean
Wrong fuel in your Renault Fluence mixes with whatever diesel is still inside the tank, so the proportion of the fuel that is petrol depends on how full your tank was when you filled up. When a few litres of unleaded go into a tank running near empty, they make up a much bigger part of what the engine would draw. Added to an almost full tank of up to 60 litres, the same volume is just a small share of the total.
People commonly ask how much petrol is too much. The more useful thing to check is whether the engine has been run, since running the engine is what takes the mixture out of your tank and through the pump and the injectors.
With a small amount, a drain is generally all your Fluence needs, and whatever the share, getting it emptied is the safe thing to do.
Engines fitted to your diesel Fluence
The version name on your badge tells us which motor your Fluence has, so it's worth noting before you call.
The badges on the diesel versions of the Fluence in our figures are dCi.
Being unsure which version you own does not need to stop you. Call all the same, and we'll work it out with you.
What goes on with AdBlue in a diesel Renault Fluence
Tank size works differently with AdBlue. With AdBlue in a diesel Renault Fluence, the diesel sitting inside your tank does not thin it. Being mainly water, AdBlue stays separate from your diesel and settles to the base, which is where the pump pulls from. Even a tiny volume ends up in the fuel line.
As the water in AdBlue evaporates, the urea left over forms crystals in the fuel lines and the fuel filter and corrodes the metal next to it, and AdBlue does not combust or give your pump any protection either.
The filler for AdBlue, on diesel cars that have it, frequently shares a flap with the diesel one and leads to a second tank. If your Fluence has an AdBlue filler, the diesel nozzle is the bigger of the two, and the AdBlue cap is usually blue.
How a fuel drain on your Renault Fluence works
The whole tank is emptied in a fuel drain on your Renault Fluence, however big it is in your version, without the vehicle being moved from where it sits. We pump the tainted fuel out, rinse the lines and the fuel filter, and refill with fresh diesel ahead of priming the fuel system and firing up the engine.
It does not matter whether your Fluence is sitting at the station forecourt or parked on your driveway. Clean diesel is what it runs on when the drain is finished, and so you can take it away.
What AdBlue removal from a diesel Renault Fluence takes
AdBlue collects at the bottom of your tank instead of blending in, so clearing it entirely is the opening stage in AdBlue removal from a diesel Renault Fluence. Where the motor has been run, the fuel lines and the fuel filter are purged through as well, and the fuel filter is changed if necessary.
AdBlue that has gone into the diesel tank is the topic here. Turning off or removing your car's AdBlue system isn't part of it.
The cost of a fuel drain on the Renault Fluence
We don't publish a fixed price, since two call-outs on the same model can be rather dissimilar. The biggest factor is whether anyone has started or driven the Fluence. Then there is the quantity that went in against how big the tank is, which liquid it was, and where your car is at the moment.
Ring with those details and we can explain what this job will involve.
Questions on the tank and petrol in a diesel Renault Fluence
Fuel tank capacity of the Renault Fluence: how much does it hold?
The same tank is fitted to each version in our figures, holding 60 litres.
With a larger tank, is petrol less of an issue?
A bigger tank means a few litres form less of the whole, yet the petrol is still in there and still gets to the pump when your engine runs. With your Fluence turned off, a drain clears all of it.
How many diesel versions of the Fluence do you list?
Our data cover 2 diesel versions of the Fluence, all set out in the table above, and so you can find yours there using the name shown on its badge.
Is it wrong fuel in my Renault Fluence if it is not diesel?
Just diesel goes in your diesel tank. Petrol of any grade, super unleaded included, is wrong fuel, and so is AdBlue, which goes in a tank of its own.
Do you come to the Renault Fluence to drain it?
Yes, we can. We travel to the car, whether it's still on the station forecourt or parked at home, so it doesn't need to be shifted or started.
