Tank Sizes and Petrol in a Diesel Fiat Croma
The capacity of your fuel tank is among the first points to know once you have put petrol in a diesel Fiat Croma, as the share of what is in there that is now petrol rests on it. The tank size and the engines are set out on this page for each Fiat Croma version which we have figures for.
The guidance doesn't vary with the number once it has occurred. Keep your engine off and call Petrol in Diesel, and we will come over to empty the vehicle where it sits.
The Fiat Croma fuel tank capacity for each version
The Fiat Croma carries the same diesel tank across each version we have data for, and that tank takes 62 litres.
| Version | Fuel tank |
|---|---|
| Fiat Croma 1.9 Multijet 16V | 62 litres |
| Fiat Croma 1.9 Multijet 8V | 62 litres |
| Fiat Croma 2.4 Multijet 20V | 62 litres |
A couple of litres of wrong fuel in your Fiat Croma, and what they amount to
The share of petrol depends on how full your tank was before you refuelled. That is because wrong fuel in your Fiat Croma blends with whatever diesel is already in it. In a tank which holds up to 62 litres, a few litres of petrol on top of an almost full tank is a small part of the total, and the same few litres going into a tank which was almost empty makes up a much bigger part of what the motor would pull through.
Often, people want to know at what point the petrol gets to be too much. Starting the motor is what takes the blend out of the tank and through the pump and the injectors, and so the more useful thing to find out is whether it has run.
Having it drained is the sensible course whatever the proportion is. If the amount is small, your Croma normally needs no more than that.
The engines in your diesel Croma
Before you call, it's worth noting the version name on the badge, since it shows us which engine your Croma has.
Our figures list Multijet badges on all diesel versions of the Croma.
In the Croma 2.4 Multijet 20V the motor reaches 2.4 litres, and in the Croma 1.9 Multijet 16V it is 1.9 litres, the lowest of them.
Phone all the same if you're not sure which version you own, and we will work it out with you.
AdBlue in a diesel Fiat Croma
Where AdBlue is concerned, the fuel tank size works differently. If you have got AdBlue in a diesel Fiat Croma, the diesel around it does not weaken it, because AdBlue is mainly water and doesn't mix with diesel. It settles to the base of your tank, which is where the fuel pump pulls from, and so even a small amount gets into your fuel lines.
AdBlue does not combust and gives your pump no protection, and as its water evaporates, the urea left behind forms crystals in the lines and the filter and attacks the metalwork around it.
A second tank with its own filler carries the AdBlue on some diesel vehicles, frequently beside the filler for diesel under the same fuel flap. On any Croma with an AdBlue filler, a blue cap generally marks it, and that cap accepts a slimmer nozzle than the diesel one.
A fuel drain on your Fiat Croma, step by step
A fuel drain on your Fiat Croma clears the whole tank, whatever its size on your version, and it is done where the car is standing. Clean diesel goes in after the tainted fuel is pumped out and the lines and the filter are cleaned, and then the system is primed and the motor fired up.
Still on the station forecourt or parked on your drive, your Croma can be drained just the same. After this drain is done it's running on clean diesel and you can drive it away.
What AdBlue removal from a diesel Fiat Croma takes
With AdBlue sitting at the bottom of your tank and not mixed in, AdBlue removal from a diesel Fiat Croma begins by emptying your tank totally. Where the engine has run, we rinse the fuel lines and your filter through as well and change the filter if it needs it.
Removing or switching off the AdBlue system on the car isn't what this covers. It's about AdBlue that has gone into the diesel tank.
The cost of a fuel drain on the Fiat Croma
There's no fixed price published here, as call-outs on one model can differ quite a lot. The biggest factor is whether anybody has run or driven the Croma. Then there is the quantity that went in compared with how large your tank is, which fuel it was, and where your car is at the moment.
Ring with those details so we can tell you what this job will involve.
Petrol in a diesel Fiat Croma: tank queries
Fuel tank capacity of the Fiat Croma: how much does it take?
62 litres, with every version we have figures for using the same tank.
Is petrol less of a problem in a bigger tank?
That petrol is still there in a bigger tank, and still reaches your pump once the motor runs, even though a few litres form less of the whole. Leave your Croma turned off and emptying it gets all of that petrol out.
How many versions of your diesel Croma are in your data?
There are 3 diesel Croma versions in our figures, and the name on your badge tells you which row of the table above is yours.
What counts as wrong fuel in my Fiat Croma?
Only diesel belongs in the diesel tank. Petrol of any type, super unleaded too, is wrong fuel, and so is AdBlue, which belongs in a tank of its own.
Wherever the Fiat Croma is, can you drain it?
There's no need to move or start the car. Whether it's parked at home or still at the forecourt, we travel to it.
