Petrol in a Diesel Lancia Dedra: What the Tank Holds
How much petrol there now is in the blend depends on your tank, so its size is worth knowing straight away when you have put petrol in a diesel Lancia Dedra. This page sets out the tank size for every version of the Lancia Dedra we have figures for, along with the engines it was offered with.
After it has occurred, the same guidance holds whatever the number happens to be. With your engine left off, phone Petrol in Diesel and the car can be emptied where it sits.
How each version stacks up on Lancia Dedra fuel tank capacity
On the Lancia Dedra, the diesel tank takes 60 litres, and it's the same on each version we hold data for.
What a couple of litres means for wrong fuel in your Lancia Dedra
Wrong fuel in your Lancia Dedra mixes with whatever diesel is already in your tank, so the proportion of your fuel that's petrol depends on how full your tank was when you filled up. Up to 60 litres fit into your tank. Topping up an almost full one with a couple of litres of unleaded means just a small share of petrol in the whole, whereas the same quantity in a nearly empty tank makes up far more of what the motor would draw.
Drivers frequently ask how much petrol is too much. Running the motor is what takes the mixture out of your tank and through your pump and your injectors, and so the more useful point to find out is whether it has run.
Having it emptied is the right course no matter what the proportion is. If the volume is small, your Dedra generally needs nothing more than that.
Diesel Dedra engines and the badges
The engine in your Dedra shows in the version name on the badge. Note it before you ring.
Whichever version it is, the motor is 1.9 litres.
Once you ring, we can work out which version it is together, even when you are not sure of it yourself.
What goes on with AdBlue in a diesel Lancia Dedra
Where AdBlue is concerned, the fuel tank size counts differently. If you have got AdBlue in a diesel Lancia Dedra, the diesel surrounding it does not dilute it, since AdBlue is largely water and does not mix with diesel. It sinks to the base of the tank, which is where the fuel pump draws from, so even a tiny volume gets into your fuel line.
AdBlue does not combust and gives the pump no protection, and as its water dries out, the urea left over crystallises in the fuel lines and your filter and corrodes the metalwork around it.
Certain diesel vehicles hold AdBlue in a second tank with a dedicated filler, often beside the diesel one under the same flap. If your Dedra has one, the AdBlue filler cap is generally blue and fits a slimmer nozzle than the diesel one.
A fuel drain on your Lancia Dedra, step by step
Carried out where the car is standing, a fuel drain on your Lancia Dedra clears the whole tank, whatever size it is on your version. Pumping out the contaminated fuel comes first, then a rinse of the fuel lines and your fuel filter. Then we top up with clean diesel, prime your system and fire up the engine.
It doesn't matter whether your Dedra is sitting on the forecourt or left on your driveway. Once the drain is finished it's running on fresh diesel and you can take it away.
AdBlue removal from a diesel Lancia Dedra
AdBlue settles at the bottom of your tank rather than mixing in, and so clearing it entirely is the opening step of AdBlue removal from a diesel Lancia Dedra. A motor that has been run means cleaning the filter and lines through as well, and changing the fuel filter if needed.
This is about AdBlue that has gone into your diesel tank. It is not removing or disabling the AdBlue system on your car.
Pricing a fuel drain on the Lancia Dedra
There is no fixed price published on this page, since call-outs on one model can vary quite a lot. What changes it most is whether the Dedra has been started or driven, and beyond that how much got in compared with the size of the tank, whether it was petrol or AdBlue, and where the vehicle is.
We can explain what's involved in this job if you call with those facts.
