Petrol in a Diesel Alfa Romeo Brera? Start With the Tank
If you have put petrol in a diesel Alfa Romeo Brera, the capacity of its tank is one of the first points to know, since it decides how much of what is in there is now petrol. We list the tank size on each version of the Alfa Romeo Brera that our figures cover on this page, along with the engines it came with.
Whatever the figure, the advice is the same now that it has happened. Phone Petrol in Diesel with the motor switched off. We will come out to you to drain the car just where it is.
How every version compares on Alfa Romeo Brera fuel tank capacity
Every version of the Alfa Romeo Brera in our figures uses the same diesel tank, holding 70 litres.
| Version | Fuel tank |
|---|---|
| Alfa Romeo Brera 2.0 JTDM | 70 litres |
| Alfa Romeo Brera 2.4 JTDM | 70 litres |
Wrong fuel in your Alfa Romeo Brera: what a few litres means
Whatever diesel was still in the tank mixes with the wrong fuel in your Alfa Romeo Brera, and how full it was when you filled up sets how much of that mixture is petrol. When a couple of litres of unleaded go into a tank running close to empty, they make up a much bigger part of what the engine would take in. Added to an almost full tank of up to 70 litres, the same volume is just a minor share of the whole.
The quantity of petrol that is too much is something people frequently ask about. Starting the engine is what moves the blend out of your tank and through your pump and the fuel injectors, so the more helpful point to know is if it has run.
With a small volume, a fuel drain is usually all your Brera needs, and whatever the proportion, getting it drained is the right thing to do.
Engines fitted to your diesel Brera
When you ring, it is useful to have checked the badge beforehand, since the name of the version on it shows us which engine your Brera has.
Among the diesel Brera versions in our figures, the badges read JTDM.
The engines run from 2.0 litres on the Brera 2.0 JTDM to 2.4 litres in the Brera 2.4 JTDM.
Phone all the same if you're not sure which version you drive, and we will figure it out with you.
When there's AdBlue in a diesel Alfa Romeo Brera
Where AdBlue is concerned, your tank size works differently. The fuel pump takes its fuel from the base of the tank, and that's where AdBlue settles, so even a small amount reaches the fuel lines. If you have got AdBlue in a diesel Alfa Romeo Brera, your diesel surrounding it doesn't weaken it, because AdBlue is mostly water and doesn't mix with diesel.
AdBlue does not burn and gives the pump no protection, and as its water dries out, the urea left over forms crystals in the lines and the fuel filter and corrodes the metalwork next to it.
On certain diesel vehicles, AdBlue has a separate tank of its own, and its filler frequently sits next to the diesel one under the same flap. Where your Brera has one, the AdBlue cap is normally blue and takes a slimmer pump nozzle than the diesel one.
A fuel drain on your Alfa Romeo Brera, step by step
Whatever size the tank is on your version, a fuel drain on your Alfa Romeo Brera empties the lot, just where the car is parked. Clean diesel is put in after the tainted fuel is pumped out and your fuel lines and your filter are flushed, and then the system is primed and your engine started.
Still at the station forecourt or sitting on your drive, your Brera can be emptied just the same. You can take it away once the drain is finished, and it'll be running on clean diesel.
How AdBlue removal from a diesel Alfa Romeo Brera works
Draining the tank totally is where AdBlue removal from a diesel Alfa Romeo Brera starts, because AdBlue does not blend in and collects at the base instead. Where the engine has been run, your lines and your filter are purged through too, and your fuel filter is replaced if necessary.
What this covers is AdBlue that ended up in your diesel tank, not removing or switching off the AdBlue system on the vehicle.
The cost of a fuel drain on the Alfa Romeo Brera
We don't list a fixed price, because two jobs on the same model can be very dissimilar. How much went in against the size of the tank, petrol or AdBlue, and the car's location all matter, yet whether the Brera has been driven or just started affects it most.
With those facts, we can tell you what this job will need when you phone.
Your tank queries on petrol in a diesel Alfa Romeo Brera
What does the Alfa Romeo Brera fuel tank capacity amount to?
70 litres, with every version we hold figures for using the same tank.
Is petrol less of a problem in a bigger tank?
The petrol is still there in a bigger tank, and still gets to your pump when the motor runs, even though a couple of litres make up less of the whole. With your Brera switched off, a fuel drain clears all of that.
How many versions of the diesel Brera are in your data?
There are 2 diesel Brera versions in our data, and the name on the badge tells you which row of the table above is yours.
Is it wrong fuel in my Alfa Romeo Brera if it's not diesel?
Just diesel belongs in the diesel tank. Petrol of every type, super unleaded too, is wrong fuel, and so is AdBlue, which goes in a tank of its own.
Will you drain the Alfa Romeo Brera where it is?
There's no need to move or start the car. Whether it is parked on your drive or still on the forecourt, we travel to it.
