Petrol in a Diesel Jeep Cherokee: What the Tank Holds
The size of your fuel tank is among the earliest things to know once you have got petrol in a diesel Jeep Cherokee, as the share of what is in there that's now petrol rests on it. We list the tank size for every version of the Jeep Cherokee which we have figures for here, together with the engines it came with.
No matter how big the figure is, there is one thing to do after the event. As soon as you leave the engine off then call Petrol in Diesel, we'll come over to empty the vehicle where it sits.
Jeep Cherokee fuel tank capacity, version by version
Between 70 and 76 litres is the spread for the Jeep Cherokee fuel tank, and the version you own decides where yours falls.
The biggest in our figures is found on the Cherokee 2.5 TD Mounty, while the smallest is on the Cherokee 2.5 CRD.
| Version | Fuel tank |
|---|---|
| Jeep Cherokee 2.5 CRD | 70 litres |
| Jeep Cherokee 2.5 TD | 76 litres |
| Jeep Cherokee 2.5 TD Mounty | 76 litres |
Does a little quantity of wrong fuel in your Jeep Cherokee matter?
The share of petrol hinges on how full the tank was before you filled up. That is because wrong fuel in your Jeep Cherokee mixes with whatever diesel was still in there. In a tank which takes up to 76 litres, a couple of litres of petrol on top of an almost full tank makes a minor share of the whole, and the same few litres going into a tank that was almost empty makes up a much greater share of what the motor would draw.
Motorists often wonder how much petrol is too much. The more useful thing to check is whether your engine has been run, as starting it is what carries that mixture out of the tank and through the pump and your injectors.
Getting it drained is the sensible course no matter what the share is. If the volume is small, your Cherokee normally needs no more than that.
Diesel Cherokee engines and their badges
The motor in your Cherokee shows in the version name on the badge. Note it before you ring.
Diesel versions of the Cherokee within our data wear TD badging.
All of them use one engine size, 2.5 litres.
When you're not sure which version you own, ring all the same then we'll figure it out with you.
Tank size and AdBlue in a diesel Jeep Cherokee
Where AdBlue is concerned, the tank size works differently. With AdBlue in a diesel Jeep Cherokee, your diesel sitting in the tank doesn't thin it. Being mainly water, AdBlue keeps separate from the diesel and settles to the bottom, which is where the pump draws from. Even a tiny amount ends up in your fuel lines.
Nothing in AdBlue combusts, and the pump gets no lubrication from it. When its water evaporates, urea is left in the lines and your filter as crystals, and the metal next to it is eaten into.
A separate tank with its own filler holds the AdBlue on certain diesel vehicles, commonly next to the diesel filler under the same fuel flap. Where your Cherokee has an AdBlue filler, the AdBlue filler cap is normally blue and fits a smaller nozzle than the diesel one.
What a fuel drain on your Jeep Cherokee takes
Whatever size the tank is on your version, a fuel drain on your Jeep Cherokee empties the lot, right where the vehicle is parked. First the tainted fuel is pumped out, then your filter and fuel lines are purged. After refilling with clean diesel, we prime the fuel system and start your engine.
Still at the forecourt or parked on your driveway, your Cherokee can be drained either way. After this drain is done it is running on fresh diesel and you can drive it away.
What AdBlue removal from a diesel Jeep Cherokee involves
AdBlue settles at the base of your tank instead of mixing in, so clearing it fully is the opening stage of AdBlue removal from a diesel Jeep Cherokee. A motor that has run means cleaning the fuel filter and lines through as well, plus replacing the fuel filter if it needs it.
This is about AdBlue that has got into the diesel tank. It is not removing or disabling the AdBlue system on your car.
The price of a fuel drain on the Jeep Cherokee
We don't publish a fixed price, as two call-outs on the same model can be rather different. What affects it most is whether the Cherokee has been started or driven, and next how much got in compared with the size of the tank, whether it was petrol or AdBlue, and where the vehicle is.
With those details, we can let you know what the job will need when you ring.
Queries on the tank and petrol in a diesel Jeep Cherokee
What does the Jeep Cherokee fuel tank capacity amount to?
Between 70 and 76 litres, according to the version. You can find each one in the table above.
Does a bigger tank make petrol less of a problem?
In a bigger tank, petrol is a smaller part of the total, yet it hasn't gone anywhere, and it reaches your pump once your engine runs. All of that is cleared with a fuel drain, as long as your Cherokee is switched off.
How many diesel versions of the Cherokee do you list?
Your badge shows which of the 3 diesel versions of the Cherokee in the table above is yours, as we hold data for each.
Is it wrong fuel in my Jeep Cherokee if it is not diesel?
Petrol counts whatever the type, super unleaded too, and so does AdBlue that was intended for its own separate tank. Everything other than diesel in the diesel tank is wrong fuel.
Will you drain the Jeep Cherokee where it stands?
We do. The car doesn't need to be moved or switched on, since we come to it whether it is still on the station forecourt or parked on your drive.
