Petrol in a Diesel Kia Carnival: What the Tank Holds
How much petrol there currently is in that mix hinges on your tank, so its size is worth finding out early when you've put petrol in a diesel Kia Carnival. The tank and the engines are set out here for each Kia Carnival version that we hold data for.
No matter what the number is, there is one piece of advice after the mistake. With the motor left off, ring Petrol in Diesel and the car can be drained where it is.
The Kia Carnival fuel tank capacity for every version
Each version of the Kia Carnival within our data uses the same diesel tank, holding 75 litres.
| Version | Fuel tank |
|---|---|
| Kia Carnival 2.9 CRDi | 75 litres |
| Kia Carnival TD RS | 75 litres |
Wrong fuel in your Kia Carnival: what a few litres means
How full the tank was when you refuelled sets the share of petrol, because wrong fuel in your Kia Carnival blends with whatever diesel is still there. When a couple of litres of unleaded are put into a tank sitting near empty, they make up a much bigger part of what the engine would take in. Added to a nearly full tank of up to 75 litres, the same amount is just a small share of the whole.
The amount of petrol that's too much is something drivers often ask about. Running the engine is what takes the blend from the tank and through your pump and your injectors, and so the more helpful point to find out is if it has run.
With a small quantity, a fuel drain is generally all your Carnival needs, and whatever the share, having it drained is the sensible thing to do.
Which engines your diesel Carnival came with
The engine in your Carnival is given in the version name on the badge. Read it before you call.
Diesel versions of the Carnival in our figures carry CRDi and TD badges.
The CRDi badge shows up on more of them than any other, while the Carnival TD RS is a version that has the TD badge instead.
The motors are each 2.9 litres.
Phone anyway if you are not sure which version you have, then we will work it out with you.
Fuel tank size and AdBlue in a diesel Kia Carnival
With AdBlue, fuel tank size plays out differently. With AdBlue in a diesel Kia Carnival, your diesel sitting in the tank does not thin it. Being mostly water, AdBlue stays separate from the diesel and sinks to the bottom, which is where your pump pulls from. Even a small quantity ends up in the fuel line.
AdBlue doesn't combust and gives your pump no protection, and as its water evaporates, the urea left over crystallises in the fuel lines and the fuel filter and eats into the metalwork next to it.
Some diesel cars hold AdBlue in a separate tank with a dedicated filler, often beside the diesel one under the same flap. If your Carnival has an AdBlue filler, the diesel pump nozzle is the bigger of the two, and the AdBlue cap is generally blue.
Fuel drain on your Kia Carnival
Done where the car is parked, a fuel drain on your Kia Carnival empties the whole tank, whatever size the tank is on your version. Pumping out the contaminated fuel comes first, followed by a rinse of your lines and the fuel filter. Then we refill with fresh diesel, prime the system and start the engine.
Whether your Carnival is still on the station forecourt or parked on your drive doesn't change a thing. Fresh diesel is what it runs on once this drain is done, and so you can drive it away.
What AdBlue removal from a diesel Kia Carnival involves
AdBlue collects at the base of your tank rather than mixing in, and so clearing it totally is the opening stage of AdBlue removal from a diesel Kia Carnival. An engine that has run means flushing your filter and lines through too, and replacing your fuel filter if it needs it.
This is about AdBlue that has gone into the diesel tank. It is not removing or disabling the AdBlue system on your car.
The cost of a fuel drain on the Kia Carnival
The same model can make for quite dissimilar call-outs, which is why we don't publish a fixed price. The biggest factor is whether anyone has started or driven the Carnival. Then comes the amount that went in compared with how large the tank is, what liquid it was, and where the vehicle is now.
With those details, we can tell you what the job will involve when you phone.
Queries on your tank and petrol in a diesel Kia Carnival
How many litres is the Kia Carnival fuel tank capacity?
It takes 75 litres, and each version we have figures for shares the same tank.
With a bigger tank, is petrol less of an issue?
In a bigger tank, petrol makes up a smaller share of the total, yet it has not gone anywhere, and it gets to your pump once your engine runs. With your Carnival switched off, a drain clears all of that.
How many versions of your diesel Carnival are in your figures?
We have figures for 2 diesel versions of the Carnival, so you can pick out yours in the table above by the model name on the badge.
Which fuels, other than diesel, would be wrong fuel in my Kia Carnival?
Just diesel belongs in the diesel tank. Petrol of any grade, super unleaded too, is wrong fuel, and so is AdBlue, which goes in a tank of its own.
Wherever the Kia Carnival is, can you drain the car?
We do. The vehicle does not need to be moved or switched on, because we travel to it whether it's still on the station forecourt or parked on your drive.
