Petrol in a Diesel Hyundai Tucson? Start With the Tank
The size of your fuel tank is among the earliest points worth knowing after you have got petrol in a diesel Hyundai Tucson, because the proportion of what is in there that is currently petrol hinges on it. Each version of the Hyundai Tucson we have data for is on this page alongside its fuel tank capacity, and so are the motors it came with.
Regardless of how big the number is, there is one piece of advice after the event. With your engine left off, ring Petrol in Diesel and your car can be drained where it is.
How every version compares on Hyundai Tucson fuel tank capacity
Each version of the Hyundai Tucson within our figures shares the same diesel tank, holding 58 litres.
| Version | Fuel tank |
|---|---|
| Hyundai Tucson 2.0 CRDi 2WD | 58 litres |
| Hyundai Tucson 2.0 CRDi 4WD | 58 litres |
| Hyundai Tucson 2.0 CRDi VGT 2WD | 58 litres |
| Hyundai Tucson 2.0 CRDi VGT 4WD | 58 litres |
What a couple of litres amounts to for wrong fuel in your Hyundai Tucson
How full your tank was when you refuelled determines the proportion of petrol, as wrong fuel in your Hyundai Tucson blends with whatever diesel was already in it. In a tank which holds up to 58 litres, a couple of litres of unleaded on top of a nearly full tank is a small share of the total, and the same few litres going into a tank which was nearly empty makes up a much greater part of what your engine would draw.
The quantity of petrol that is too much is something people commonly wonder about. It's more helpful to find out whether the engine has been run, as a running engine is what carries that mixture from the tank and through your pump and your injectors.
A fuel drain is the right course whatever the proportion, and with a small volume it's normally all your Tucson needs.
Diesel Tucson engines and their badges
Before you phone, it is worth checking the version name on the badge, since it shows us which motor your Tucson has.
Our data give CRDi badges on the diesel versions of the Tucson.
Whichever version it is, the motor is 2.0 litres.
If you're not certain which version you own, call anyway then we will work it out together.
When there's AdBlue in a diesel Hyundai Tucson
With AdBlue, tank size plays out differently. The fuel pump takes its fuel from the bottom of the tank, and that is where AdBlue settles, and so even a tiny volume reaches your fuel line. If you have AdBlue in a diesel Hyundai Tucson, your diesel surrounding it doesn't dilute it, because AdBlue is mainly water and doesn't blend with it.
AdBlue does not burn and gives the pump no lubrication, and as its water evaporates, the urea left over forms crystals in the lines and the filter and eats into the metal around it.
Some diesel vehicles hold AdBlue in a separate tank with a dedicated filler, often alongside the diesel one under the same flap. If your Tucson has an AdBlue filler, the diesel nozzle is the bigger of the two, and the AdBlue cap is generally blue.
What a fuel drain on your Hyundai Tucson involves
Whatever size your tank is on your version, a fuel drain on your Hyundai Tucson clears all of it, just where the vehicle is sitting. We pump the contaminated fuel out, flush the fuel lines and the filter, and fill up again with fresh diesel before priming your system and firing up the engine.
Left at home or still at the pumps, your Tucson receives the same drain. After we finish the drain, the car is running on clean diesel and ready to drive away.
AdBlue removal from a diesel Hyundai Tucson
AdBlue removal from a diesel Hyundai Tucson starts with emptying the tank entirely, as AdBlue collects at the base rather than blending in. Where the engine has been run, the fuel lines and the filter are cleaned through too, and your fuel filter is replaced if needed.
This covers AdBlue that has gone into the diesel tank. It's not taking out or switching off the AdBlue system on the car.
How the quote of a fuel drain on the Hyundai Tucson is set
Two jobs on the same model can be quite dissimilar, and so we do not list a fixed price. Whether the Tucson has been run or driven affects it most. After that it rests on how much got in against your fuel tank size, whether petrol or AdBlue got in, and your car's location.
We can tell you what is involved in this job if you phone with those facts.
Tank queries about petrol in a diesel Hyundai Tucson
What does the Hyundai Tucson fuel tank capacity amount to?
The same tank is fitted to each version in our figures, holding 58 litres.
Does petrol matter less in a larger tank?
A bigger tank means a few litres form less of the whole, yet the petrol is still there and still gets to your pump once the engine runs. Keep your Tucson turned off and draining it gets all of that petrol out.
Diesel versions of the Tucson: how many do you list?
We have figures for 4 diesel versions of the Tucson, so you can pick out yours in the table above by the model name on the badge.
Is it wrong fuel in my Hyundai Tucson if it's not diesel?
Petrol qualifies whatever the type, super unleaded included, and so does AdBlue that was meant for its own separate tank. Anything other than diesel in the diesel tank is wrong fuel.
Wherever the Hyundai Tucson is, can you drain the vehicle?
Yes. We come to the vehicle, whether it is still on the forecourt or parked on your drive, so it doesn't need to be moved or started.
