What the Tank Holds: Petrol in a Diesel Toyota Picnic
Anyone who has put petrol in a diesel Toyota Picnic wants to know the capacity of its tank early, because that settles what share of the fuel in there is currently petrol. Every version of the Toyota Picnic we have figures for is listed on this page alongside its fuel tank capacity, and the same goes for the motors it came with.
When it has occurred, the same advice holds whatever the size happens to be. With the engine kept off, ring Petrol in Diesel and your car will be drained where it is.
Version by version: Toyota Picnic fuel tank capacity
Each version of the Toyota Picnic within our figures uses one diesel tank, which takes 60 litres.
Does a small amount of wrong fuel in your Toyota Picnic matter?
Wrong fuel in your Toyota Picnic mixes with whatever diesel is already inside your tank, so the part of it that's petrol hinges on how full your tank was when you refuelled. When a couple of litres of petrol are put into a tank sitting close to empty, they form a far greater part of what the engine would take in. Added to a nearly full tank of up to 60 litres, the same volume is just a small share of the whole.
The amount of petrol that is too much is something drivers commonly ask about. The more useful point to find out is whether the engine has run, because starting it is what takes that mixture from the tank and through the pump and your injectors.
Whatever the share, the safe thing is to have it drained, and with a small quantity a drain is generally all your Picnic needs.

Fuel tank size and AdBlue in a diesel Toyota Picnic
AdBlue alters what the capacity of the tank means. With AdBlue in a diesel Toyota Picnic, your diesel sitting in the tank doesn't dilute it. Being mostly water, AdBlue stays separate from the diesel and sinks to the bottom, which is where your pump pulls from. Even a tiny amount ends up in the fuel line.
As the water in AdBlue dries out, the urea left behind forms crystals in the fuel lines and the fuel filter and eats into the metal next to it, and AdBlue does not combust or give the pump any lubrication either.
A separate tank with a dedicated filler holds the AdBlue on some diesel vehicles, often alongside the filler for diesel under the same fuel flap. On any Picnic with an AdBlue filler, a blue cap normally marks it, and that cap fits a slimmer nozzle than the diesel one.
A fuel drain on your Toyota Picnic, step by step
Done where your car is standing, a fuel drain on your Toyota Picnic empties the whole tank, whatever size it is on your version. Clean diesel is put in once the tainted fuel gets pumped out and the lines and the fuel filter are rinsed, and then the system is primed and the motor fired up.
Still on the forecourt or sitting on your drive, your Picnic can be drained either way. You can take it away after this drain is done, and it will be running on clean diesel.
AdBlue removal from a diesel Toyota Picnic, explained
With AdBlue sitting at the bottom of the tank rather than blended in, AdBlue removal from a diesel Toyota Picnic begins by clearing the tank completely. Where the engine has been run, the lines and your filter are cleaned through too, and your fuel filter is changed if necessary.
Taking out or disabling the AdBlue system on your car isn't what this is about. It's about AdBlue that has gone into your diesel tank.
The cost of a fuel drain on the Toyota Picnic
Two jobs on the same model can be rather dissimilar, so we do not list a fixed price. What changes it most is whether the Picnic has been run or driven, and after that how much went in against the capacity of your tank, whether it was petrol or AdBlue, and where the vehicle is now.
With those facts, we can let you know what this job will need when you phone.
Queries on your tank and petrol in a diesel Toyota Picnic
Fuel tank capacity of the Toyota Picnic: how much does it hold?
60 litres, with each version we hold figures for sharing the same tank.
Does petrol matter less in a bigger tank?
In a bigger tank, petrol makes up a smaller share of the whole, yet it hasn't gone anywhere, and it reaches your pump as soon as the motor runs. With your Picnic turned off, a fuel drain removes all of it.
Which fuels, other than diesel, would be wrong fuel in my Toyota Picnic?
Just diesel goes in the diesel tank. Petrol of every type, super unleaded too, is wrong fuel, and so is AdBlue, which goes in a tank of its own.
Will you drain the Toyota Picnic where it stands?
We do. The vehicle doesn't need to be moved or switched on, because we travel to it whether it is still on the forecourt or parked at home.
