Tank Sizes and Petrol in a Diesel Toyota Auris
How much petrol there currently is in that mix hinges on the tank, so its size is well worth checking early on when you've put petrol in a diesel Toyota Auris. We give the tank for every version of the Toyota Auris which our figures cover on this page, together with the engines it came with.
Regardless of how big the number is, there's one thing to do after the mistake. Phone Petrol in Diesel with the motor kept off. We will come out to you to drain the car right where it stands.
Each version in turn: Toyota Auris fuel tank capacity
The diesel tank on the Toyota Auris takes anywhere between 50 and 55 litres, depending on what version you own.
Our data place the largest tank on the Auris 2.2 D-CAT and the smallest on the Auris Touring Sports 2.0 D-4D.
| Version | Fuel tank |
|---|---|
| Toyota Auris 1.4 D-4D | 55 litres |
| Toyota Auris 2.0 D-4D | 55 litres |
| Toyota Auris 2.2 D-CAT | 55 litres |

| Toyota Auris Touring Sports 2.0 D-4D | 50 litres |
Wrong fuel in your Toyota Auris: what a few litres amounts to
The share of petrol hinges on how full your tank was before you refuelled. That is because wrong fuel in your Toyota Auris mixes with whatever diesel was still in it. When a few litres of petrol go into a tank running near empty, they make up a much greater part of what the motor would take in. Added to a nearly full tank of up to 55 litres, the same amount is only a small share of the total.
People often want to know how much petrol counts as too much. It is more useful to find out whether the engine has been run, as a running motor is what takes that mixture from the tank and through your pump and the injectors.
Whatever the share, the sensible thing is to have it emptied, and with a modest quantity a fuel drain is normally all your Auris needs.
The engines fitted to the diesel Auris
Your engine in your Auris shows in the version name on the badge. Note it before you phone.
Among the diesel Auris versions in our data, the badges read D-4D.
There are Touring Auris versions in the figures as well.
When you ring, we can figure out which version it is between us, even when you are not certain of it yourself.
What happens with AdBlue in a diesel Toyota Auris
AdBlue changes what the capacity of your tank means. The fuel pump draws its fuel from the base of the tank, and that is where AdBlue settles, so even a tiny volume gets into your fuel line. If you have AdBlue in a diesel Toyota Auris, the diesel surrounding it does not dilute it, since AdBlue is largely water and doesn't blend with diesel.
Nothing in AdBlue combusts, and the pump gets no lubrication from it. After its water evaporates, urea is left in the fuel lines and the filter as crystals, and the metal next to it corrodes.
A separate tank with its own filler holds the AdBlue on some diesel vehicles, commonly next to the diesel filler under the same flap. Where your Auris has an AdBlue filler, its filler cap is normally blue and fits a smaller pump nozzle than the diesel one.
A fuel drain on your Toyota Auris, step by step
A fuel drain on your Toyota Auris empties the entire tank, whatever its size on your version, and it's done where the car is parked. We pump the tainted fuel out, flush the lines and the filter, and fill up again with fresh diesel ahead of re-priming your system and firing up the motor.
It does not matter whether your Auris is sitting on the forecourt or parked on your driveway. Fresh diesel is what it runs on when this drain is done, and so you can take it away.
AdBlue removal from a diesel Toyota Auris, explained
AdBlue removal from a diesel Toyota Auris starts with draining the tank fully, as AdBlue gathers at the bottom instead of mixing in. Where the motor has run, the fuel lines and your filter are cleaned through too, and the fuel filter is replaced if needed.
AdBlue that has gone into your diesel tank is the subject here. Switching off or taking out the car's AdBlue system is not part of it.
The cost of a fuel drain on the Toyota Auris
We don't list a fixed price, since two call-outs on the same model can be rather dissimilar. Whether the Auris has been run or driven affects it most. After that it rests on how much was put in against the tank size, whether petrol or AdBlue got in, and your car's location.
With those facts, we can let you know what the job will involve when you call.
Petrol in a diesel Toyota Auris: tank queries
Fuel tank capacity of the Toyota Auris: how much does it take?
Each version is listed above in the table, with tanks from 50 to 55 litres depending on which one you have.
Is petrol less of a problem in a bigger tank?
In a larger tank, petrol makes up a smaller share of the total, yet it has not gone anywhere, and it reaches the pump once the engine runs. A drain clears all of it while your Auris stays switched off.
Do you cover more than one diesel Auris?
Your badge tells you which of the 5 diesel versions of the Auris in the table above is yours, since we have data for each.
Which fuels, other than diesel, would be wrong fuel in my Toyota Auris?
Just diesel belongs in the diesel tank. Petrol of any grade, super unleaded included, is wrong fuel, and so is AdBlue, which belongs in a tank of its own.
Can you drain the Toyota Auris where it is?
Yes, we can. We travel to the vehicle, whether it's still on the station forecourt or parked on your drive, so it does not need to be moved or switched on.
