Petrol in a Diesel Kia Sorento? Start With the Tank
Anyone who has put petrol in a diesel Kia Sorento wants to find out the capacity of its fuel tank early on, as that settles what share of the fuel in there is currently petrol. Our page sets out the tank size for each version of the Kia Sorento we keep data for, plus the engines it came with.
When it has happened, the same advice holds whatever the size is. Ring Petrol in Diesel with the motor kept off. We'll come to you and drain the car right where it sits.
Kia Sorento fuel tank capacity, version by version
Depending on which version you own, the diesel tank on the Kia Sorento holds anywhere from 70 to 80 litres.
Of the versions in our figures, the Sorento 2.5 CRDi has the biggest tank, with the smallest on the Sorento 2.2 CRDi 2WD.
| Version | Fuel tank |
|---|---|
| Kia Sorento 2.2 CRDi 2WD | 70 litres |
| Kia Sorento 2.2 CRDi 4WD | 70 litres |
| Kia Sorento 2.5 CRDi | 80 litres |
What a few litres means with wrong fuel in your Kia Sorento
How full your tank was when you filled up sets the share of petrol, because wrong fuel in your Kia Sorento mixes with whatever diesel is still in it. Up to 80 litres fit in your tank. Topping up a nearly full one with a couple of litres of petrol means only a minor share of petrol in the total, while the same amount in a nearly empty tank is much more of what your engine would take in.
People frequently wonder how much petrol is too much. The more useful thing to find out is if the engine has been run, since starting it is what moves the mixture out of the tank and through the pump and the injectors.
Getting it drained is the safe option no matter what the share is. When the volume is modest, your Sorento generally needs nothing more than that.
The engines on your diesel Sorento
The version name on your badge tells us which engine your Sorento has, so it's worth reading before you ring.
Across all diesel Sorento versions in our data, the badges read CRDi.
Not knowing which version you own does not need to stop you. Call anyway, and we'll figure it out with you.
AdBlue in a diesel Kia Sorento
AdBlue changes what the size of the tank means. The fuel pump draws its fuel from the base of your tank, and that's where AdBlue sinks, so even a tiny quantity gets into the fuel line. If you have AdBlue in a diesel Kia Sorento, your diesel around it doesn't dilute it, as AdBlue is largely water and does not mix with it.
As the water in AdBlue dries out, the urea left behind forms crystals in your lines and your filter and corrodes the metalwork next to it, and AdBlue does not burn or give your pump any protection either.
On certain diesel cars, AdBlue has a second tank of its own, and its filler frequently is alongside the diesel filler under the same flap. Where your Sorento has an AdBlue filler, its cap is normally blue and accepts a slimmer pump nozzle than the diesel filler.
What a fuel drain on your Kia Sorento takes
A fuel drain on your Kia Sorento clears the entire tank, whatever its size in your version, and it's done where your car is sitting. We draw the tainted fuel out, flush the lines and the filter, and fill up again with clean diesel ahead of priming the system and firing up the motor.
Still on the forecourt or parked on your drive, your Sorento can be drained just the same. Fresh diesel is what it runs on when this drain is finished, so you can drive it away.
What AdBlue removal from a diesel Kia Sorento takes
Clearing the tank completely is how AdBlue removal from a diesel Kia Sorento begins, because AdBlue doesn't blend in and settles at the base instead. Where the engine has run, the fuel lines and the fuel filter are flushed through as well, and your fuel filter is changed if necessary.
What this covers is AdBlue that ended up in the diesel tank, not removing or disabling the AdBlue system on the car.
What a fuel drain on the Kia Sorento costs
We don't give a fixed price, since two jobs on the same model can be rather different. Whether the Sorento has been run or driven affects it most. After that it depends on how much got in against the fuel tank size, whether petrol or AdBlue was put in, and your car's location.
Those details are what we need to explain what this work involves. Ring with them to hand.
Petrol in a diesel Kia Sorento: tank questions
How many litres is the Kia Sorento fuel tank capacity?
Every version is listed above in the table, with tanks from 70 to 80 litres depending on which one it is.
With a bigger tank, is petrol less of an issue?
The petrol is still there in a larger tank, and still gets to your pump as soon as the engine runs, even though a couple of litres form less of the total. All of it comes out with a fuel drain, as long as your Sorento is switched off.
How many diesel versions of the Sorento do you list?
Your boot badge tells you which of the 3 diesel versions of the Sorento in the table above is yours, since we have figures for each.
Is it wrong fuel in my Kia Sorento if it's not diesel?
Everything except diesel in the diesel tank, which means petrol of every type, super unleaded as well, or AdBlue meant for its own separate tank.
Can you drain the Kia Sorento where it is?
Yes, wherever it is. Sitting at home or still at the pump, your car stays where it is and isn't started, because we come to it.
