Petrol in a Diesel Renault Koleos? Start With the Tank
Someone who has got petrol in a diesel Renault Koleos needs to find out the size of its fuel tank first, because that determines how much of the fuel in there is currently petrol. Every version of the Renault Koleos we hold data for is on this page with its tank capacity, and so are the engines it was sold with.
Regardless of how big the number is, there's one thing to do after the mistake. Phone Petrol in Diesel with the engine switched off. We will come out to you and drain the car just where it sits.
The Renault Koleos fuel tank capacity on every version
Every version of the Renault Koleos in our figures uses the same diesel tank, holding 65 litres.
| Version | Fuel tank |
|---|---|
| Renault Koleos 2.0 dCi FAP 4x2 | 65 litres |
| Renault Koleos 2.0 dCi FAP 4x4 | 65 litres |
What a couple of litres means for wrong fuel in your Renault Koleos
Wrong fuel in your Renault Koleos blends with whatever diesel is still in your tank, so the share of it that's petrol depends on how full the tank was when you refuelled. When a few litres of unleaded are put into a tank running near empty, they make up a far larger share of what the engine would take in. Added to an almost full tank of up to 65 litres, the same quantity is only a minor share of the total.
The amount of petrol that is too much is something motorists commonly ask about. Whether the motor has been run is the more helpful point to know. Once it runs, your pump pulls that mixture from the tank and passes it on to the fuel injectors.
Getting it drained is the right option no matter what the proportion is. When the amount is modest, your Koleos usually needs no more than that.
Engines fitted to the diesel Koleos
The version name on the badge tells us which engine your Koleos has, and so it's worth noting before you ring.

Whatever version it is, the engine is 2.0 litres.
There are 4x4 Koleos versions in the figures too.
Phone all the same if you're not sure which version you own, and we'll figure it out with you.
What goes on with AdBlue in a diesel Renault Koleos
Where AdBlue is concerned, your tank size works differently. The fuel pump draws its fuel from the bottom of your tank, and that is where AdBlue sinks, and so even a tiny amount reaches the fuel lines. If you have AdBlue in a diesel Renault Koleos, the diesel around it doesn't dilute it, since AdBlue is mostly water and doesn't mix with it.
As the water in AdBlue evaporates, the urea left behind crystallises in your lines and the fuel filter and corrodes the metalwork next to it, and AdBlue does not burn or give your pump any lubrication either.
Certain diesel vehicles carry AdBlue in a second tank with its own filler, commonly beside the diesel filler under the same flap. If your Koleos has an AdBlue filler, the diesel pump nozzle is the larger of the two, and the AdBlue cap is usually blue.
What a fuel drain on your Renault Koleos involves
Carried out where your car is standing, a fuel drain on your Renault Koleos clears the whole tank, whatever size the tank is on your version. Drawing out the contaminated fuel comes first, followed by a rinse of your lines and your fuel filter. After that we refill with clean diesel, prime the system and fire up the engine.
It does not matter whether your Koleos is still on the forecourt or left on your drive. You can drive it away once this drain is finished, and it will be running on fresh diesel.
AdBlue removal from a diesel Renault Koleos
AdBlue removal from a diesel Renault Koleos starts with draining your tank entirely, since AdBlue settles at the bottom instead of blending in. Where the motor has been started, we flush your lines and your filter through as well and change the filter if it needs it.
What this covers is AdBlue that ended up in the diesel tank, not removing or disabling the AdBlue system on your car.
How the price of a fuel drain on the Renault Koleos is worked out
There is no fixed price published on this page, as call-outs on one model can vary quite a lot. Whether the Koleos has been run or driven changes it most. After that it depends on how much went in compared with your fuel tank size, whether petrol or AdBlue got in, and the car's location.
With those details, we can explain what the job will involve when you ring.
Tank queries about petrol in a diesel Renault Koleos
How many litres is the Renault Koleos fuel tank capacity?
Each version we hold figures for uses one tank, and it holds 65 litres.
Does a bigger tank make petrol less of an issue?
A larger tank means a few litres make up less of the total, but the petrol is still there and still gets to your pump once the engine runs. A drain removes all of that as long as your Koleos stays switched off.
How many versions of the diesel Koleos are in your data?
Our figures cover 2 diesel versions of the Koleos, all set out in the table above, and so you can find yours there by the name shown on its badge.
Which fuels, other than diesel, would be wrong fuel in my Renault Koleos?
Just diesel goes in the diesel tank. Petrol of every type, super unleaded included, is wrong fuel, and so is AdBlue, which goes in a tank of its own.
Will you drain the Renault Koleos where it stands?
Yes, we can. We come to the car, whether it's still on the forecourt or parked at home, so it does not need to be moved or switched on.
