Petrol in a Diesel Toyota: Tanks Across the Range
Anyone who has put petrol in a diesel Toyota needs to check the size of the tank on their car, as that determines how much petrol is now in the mix. Every model in the diesel Toyota range has a dedicated page, linked below, and this one gives the fuel tank sizes for all of them.
The capacity doesn't change the advice. After it has happened, keep the motor off then phone Petrol in Diesel, and we'll come and empty the car where it stands.
Fuel tank sizes throughout the diesel Toyota range
The model and the version determine how much the tank takes on a diesel Toyota, anywhere from 32 litres to 96 litres across the range.
Up to 80 litres goes in the fuel tank on the Hilux.
The Verso holds at most 60 litres, according to our figures.
Between them, the 14 diesel Toyota models we list span 70 versions, and the page for every model lists the fuel tank for every one.
Does a tiny quantity of wrong fuel in your Toyota count?
Whatever diesel was still inside your tank mixes with the wrong fuel in your Toyota, and how full the tank was when you filled up determines how much of that mix is petrol. Tanks in the range hold up to 96 litres, so filling a tank that's almost full with a couple of litres of petrol leaves that petrol just a small share of the total, whereas the same few litres in an almost empty tank are a much larger part of what gets to your engine.
Drivers often want to know how much petrol is too much. Whether your engine has been run is the more helpful thing to check. Once it runs, the pump draws the mixture from your tank and pushes it on to the injectors.
A fuel drain is generally all your car needs if the quantity is modest.
Engines in the diesel Toyota range
Across the diesel Toyota models in our data, the badges are D-4D and TD.
From 1.4 litres, engine sizes across the range go up to 4.5 litres.
Reading the name of the model and the boot badge before ringing is worthwhile, as together they show us which model you drive. Being unsure does not matter. Ring all the same, and we will work it out with you.
When there's AdBlue in a diesel Toyota
With AdBlue, fuel tank size is no help. With AdBlue in a diesel Toyota, the diesel sitting inside your tank can't weaken it. Being mainly water, AdBlue stays separate from the diesel and sinks to the base, which is where the pump pulls from. Even a small volume ends up in your fuel lines.
As the water in AdBlue dries out, the urea left over forms crystals in the fuel lines and the filter, and AdBlue does not burn or give the pump any protection either.
On a diesel vehicle that has a separate AdBlue tank, the AdBlue filler often sits next to the diesel one under the same flap. Its cap is blue, and it takes a narrower nozzle.
A fuel drain on your Toyota, in detail
A fuel drain on your Toyota clears the entire tank, however big it is on your model, and it is done where your car is standing. First the tainted fuel is pumped out, then the filter and fuel lines are purged. After refilling with clean diesel, we prime the fuel system and fire up your engine.
On the Carina that means a tank of up to 60 litres.
After we finish the drain, the vehicle is free to drive away on clean diesel.
How we handle AdBlue removal from a diesel Toyota
With AdBlue sitting at the bottom of the tank and not mixed in, AdBlue removal from a diesel Toyota begins by clearing the tank completely. If the motor has run, we flush the lines and the filter through as well and replace the filter if needed.
AdBlue that has gone into the diesel tank is the subject here. Switching off or taking out the car's AdBlue system is not part of that.
What a fuel drain on a diesel Toyota costs
Two jobs on the same model can be very different, so we don't publish a fixed price. The largest factor is whether anyone has run or driven the car. Then comes the amount that was put in compared with how big your tank is, what fluid it was, and where the car is now. Phone with those facts and we can let you know what this job will take.
Queries on the tank and petrol in a diesel Toyota
Which Toyota diesel takes the most fuel?
Going by our figures it's the Land Cruiser, at up to 96 litres, while the smallest is fitted to the iQ.
Does a bigger tank make petrol less of an issue?
Less of the total is petrol when a couple of litres go into a bigger tank, yet it is still there, and running your engine still carries it to the fuel pump. With your car turned off, a drain clears all of that.
Where do I find the tank size for my exact version?
Every version we have data for is listed with its tank on the page for your model, which is linked further down.
Wrong fuel in my Toyota: what does that cover?
Only diesel belongs in the diesel tank. Petrol of every grade, super unleaded included, is wrong fuel, and so is AdBlue, which belongs in a tank of its own.
