Petrol in a Diesel Fiat Grande Punto: What the Tank Holds
How much petrol there currently is in the mix depends on the tank, and so its size is well worth checking early on if you have put petrol in a diesel Fiat Grande Punto. This page sets out the tank size on each version of the Fiat Grande Punto we have figures for, together with the engines it was sold with.
Whatever the size, the advice is the same after it has happened. Once you leave the engine off then call Petrol in Diesel, we'll come out to drain your car where it stands.
How each version compares on Fiat Grande Punto fuel tank capacity
Every version of the Fiat Grande Punto in our figures uses the same diesel tank, which takes 45 litres.
| Version | Fuel tank |
|---|---|
| Fiat Grande Punto 1.3 Multijet 16V | 45 litres |
| Fiat Grande Punto 1.9 Multijet 8V | 45 litres |
Does a small amount of wrong fuel in your Fiat Grande Punto count?
Whatever diesel is already in your tank mixes with the wrong fuel in your Fiat Grande Punto, and how full it was when you filled up decides how much of that mix is petrol. When a couple of litres of unleaded are put into a tank running near empty, they make up a much larger part of what the motor would take in. Added to a nearly full tank of up to 45 litres, the same volume is only a small share of the whole.
The quantity of petrol that is too much is something people often wonder about. It is more useful to know if the motor has been run, since a running engine is what carries the blend from your tank and through your pump and your injectors.
Getting it emptied is the safe course whatever the share is. If the quantity is small, your Grande Punto usually needs no more than that.
Which engines the diesel Grande Punto came with
The version name on the badge tells us which motor your Grande Punto has, so it's worth checking before you ring.
Our figures give Multijet badges on the diesel versions of the Grande Punto.
In the Grande Punto 1.9 Multijet 8V the motor reaches 1.9 litres, and in the Grande Punto 1.3 Multijet 16V it's 1.3 litres, the lowest of them.
If you are not sure which version you have, ring anyway and we will figure it out together.
What goes on with AdBlue in a diesel Fiat Grande Punto
Tank size works differently with AdBlue. With AdBlue in a diesel Fiat Grande Punto, the diesel sitting inside the tank does not dilute it. Being largely water, AdBlue stays separate from the diesel and sinks to the base, which is where your pump pulls from. Even a tiny amount gets into your fuel line.
AdBlue gives your pump no protection and won't combust. Its water evaporates as it sits, leaving urea that crystallises in the fuel filter and the fuel lines, where it eats into the metalwork it sits against.
Certain diesel vehicles hold AdBlue in a separate tank with its own filler, often next to the diesel filler under the same fuel flap. On any Grande Punto with an AdBlue filler, a blue cap generally marks it, and that cap takes a smaller nozzle than the diesel one.
A fuel drain on your Fiat Grande Punto, step by step
A fuel drain on your Fiat Grande Punto empties the entire tank, whatever its size on your version, and it is carried out where the car is parked. We pump the contaminated fuel out, flush the fuel lines and the filter, and fill up again with fresh diesel ahead of re-priming the fuel system and starting the engine.
Still at the station forecourt or parked on your drive, your Grande Punto can be drained just the same. After this drain is finished it is running on fresh diesel and you can take it away.
AdBlue removal from a diesel Fiat Grande Punto
AdBlue collects at the bottom of the tank instead of mixing in, and so draining it totally is the opening step of AdBlue removal from a diesel Fiat Grande Punto. We also flush the lines and the filter through once the motor has been started, replacing the filter when it needs changing.
AdBlue that has got into your diesel tank is the topic here. Disabling or removing the car's AdBlue system is not part of that.
What a fuel drain on the Fiat Grande Punto costs
The same model can make for quite dissimilar call-outs, which is why we do not list a fixed price. The largest factor is whether anyone has started or driven the Grande Punto. Then comes the amount that got in against how big your tank is, which liquid it was, and where the vehicle is now.
We can let you know what's involved in this job once you ring with those details.
Tank queries about petrol in a diesel Fiat Grande Punto
What's the fuel tank capacity of the Fiat Grande Punto?
Each version we hold data for uses one tank, and it holds 45 litres.
With a larger tank, is petrol less of a problem?
A bigger tank means a couple of litres form less of the total, yet the petrol is still in there and still gets to your pump when the engine runs. All of that comes out with a drain, as long as your Grande Punto is switched off.
Diesel versions of the Grande Punto: how many do you list?
Your badge shows which of the 2 diesel versions of the Grande Punto in the table above is yours, since we have data for each.
Which fuels, other than diesel, would be wrong fuel in my Fiat Grande Punto?
Petrol qualifies whatever the grade, super unleaded too, and so does AdBlue that was meant for its own dedicated tank. Everything other than diesel in the diesel tank is wrong fuel.
Can you drain the Fiat Grande Punto where it is?
There's no need to shift or start the vehicle. Whether it is left on your drive or still at the station forecourt, we come to it.
