Petrol in a Diesel Fiat Idea: What the Tank Holds
Once you have got petrol in a diesel Fiat Idea, the capacity of its fuel tank is among the earliest things to know, since it determines how much of what is in there is now petrol. The tank and the engines are set out on this page for each Fiat Idea version which we hold data for.
The advice does not change with the figure once it has happened. Once you leave the motor off and call Petrol in Diesel, we'll come out to empty the car where it sits.
How every version compares on Fiat Idea fuel tank capacity
Each version of the Fiat Idea in our figures uses one diesel tank, holding 47 litres.
| Version | Fuel tank |
|---|---|
| Fiat Idea 1.3 JTD 70 16V | 47 litres |
| Fiat Idea 1.3 Multijet 16V | 47 litres |
| Fiat Idea 1.9 JTD 100 8V | 47 litres |
Wrong fuel in your Fiat Idea: what a couple of litres means
How full the tank was when you refuelled decides the share of petrol, as wrong fuel in your Fiat Idea mixes with whatever diesel was already in it. In a tank that holds up to 47 litres, a few litres of unleaded added to a nearly full tank is a minor share of the total, and the same few litres going into a tank which was almost empty makes up a far greater share of what your engine would draw.
Frequently, people ask at what point the petrol gets to be too much. The more useful thing to check is if the motor has been run, because starting the engine is what takes the blend out of your tank and through your pump and your injectors.
Whatever the share, the safe course is to get it emptied, and with a modest quantity a fuel drain is generally all your Idea needs.
Which engines your diesel Idea came with
When you phone, it is useful to have checked the badge first, as the name of the version on it shows us which motor your Idea has.
Our data list JTD and Multijet badges on all diesel versions of the Idea.
In the Idea 1.9 JTD 100 8V the motor reaches 1.9 litres, and in the Idea 1.3 Multijet 16V it's 1.3 litres, the smallest of them.
Call anyway if you are not sure which version you drive, then we will work it out with you.
When there's AdBlue in a diesel Fiat Idea
Where AdBlue is concerned, the tank size counts differently. The fuel pump draws its fuel from the bottom of your tank, and that is where AdBlue settles, so even a tiny volume gets into the fuel line. If you have AdBlue in a diesel Fiat Idea, the diesel around it does not weaken it, because AdBlue is mainly water and doesn't mix with diesel.
As the water in AdBlue evaporates, the urea left over crystallises in the lines and the filter and attacks the metalwork around it, and AdBlue does not combust or give your pump any protection either.
On certain diesel cars, AdBlue has a second tank of its own, and its filler often is next to the diesel filler under the same flap. Where your Idea has an AdBlue filler, its filler cap is generally blue and accepts a narrower nozzle than the diesel one.
What a fuel drain on your Fiat Idea takes
The whole tank is emptied in a fuel drain on your Fiat Idea, however large it is in your version, without your car moving from where it stands. Fresh diesel goes in once the contaminated fuel is pumped out and the lines and the filter are cleaned, and then the system is primed and your engine started.
It makes no difference whether your Idea is sitting at the station forecourt or parked on your drive. When the drain is finished it's running on clean diesel and you can drive it away.
What AdBlue removal from a diesel Fiat Idea takes
Clearing the tank fully is how AdBlue removal from a diesel Fiat Idea starts, since AdBlue does not mix in and collects at the base instead. An engine that has run means cleaning the filter and lines through as well, plus replacing the fuel filter if it needs it.
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.
What a fuel drain on the Fiat Idea will cost
Two jobs on the same model can be rather dissimilar, and so we do not list a fixed price. What changes it most is whether the Idea has been run or driven, and after that how much was put in against the capacity of your tank, whether it was petrol or AdBlue, and where the vehicle is now.
Those details are what we need to tell you what this work involves. Phone with them to hand.
Questions on your tank and petrol in a diesel Fiat Idea
What is the fuel tank capacity of the Fiat Idea?
47 litres, with every version we have figures for sharing the same tank.
Does petrol matter less with a larger tank?
A larger tank means a couple of litres make up less of the whole, but that petrol is still there and still gets to the pump once the engine runs. Leave your Idea switched off and emptying it gets every bit of the petrol out.
How many versions of the diesel Idea are in your figures?
Our figures cover 3 diesel versions of the Idea, all listed in the table above, so you can find yours there by the name shown on its badge.
Wrong fuel in my Fiat Idea: what does that include?
Only diesel belongs in your diesel tank. Petrol of every grade, super unleaded included, is wrong fuel, and so is AdBlue, which belongs in a tank of its own.
Do you come to the Fiat Idea to drain it?
We do. Your car doesn't need to be shifted or started, because we come to it whether it's still at the station forecourt or left at home.
