Petrol in a Diesel Volvo C70: What the Tank Holds
Once you have put petrol in a diesel Volvo C70, the size of its fuel tank is among the first points worth knowing, as it determines how much of what is in there is now petrol. Each version of the Volvo C70 we have data for is listed on this page with its fuel tank size, and the same goes for the motors it was sold with.
No matter what the figure is, there is a single thing to do after the event. As soon as you leave the engine off and call Petrol in Diesel, we will come over to drain the vehicle where it sits.
How each version compares on Volvo C70 fuel tank capacity
Depending on which version you own, the diesel tank on the Volvo C70 takes anywhere from 60 to 62 litres.
Our figures put the biggest tank on the C70 D5 and the smallest in the C70 D4.
As a comparison, 60 litres is the capacity for the C70 D3.
| Version | Fuel tank |
|---|---|
| Volvo C70 2.0D | 62 litres |
| Volvo C70 D3 | 60 litres |
| Volvo C70 D4 | 60 litres |
| Volvo C70 D5 | 62 litres |
| Volvo C70 D5 automatik | 62 litres |
What a couple of litres means for wrong fuel in your Volvo C70
Wrong fuel in your Volvo C70 mixes with whatever diesel is already inside your tank, and so the part of your fuel that is petrol rests on how full the tank was when you filled up. When a few litres of petrol go into a tank sitting near empty, they make up a much larger share of what the engine would draw. Added to a nearly full tank of up to 62 litres, the same volume is only a small share of the whole.
People often want to know how much petrol counts as too much. The more useful thing to check is whether your engine has been run, since starting the engine is what carries the mixture from the tank and through your pump and the injectors.
Whatever the proportion, the sensible course is to have it emptied, and with a small volume a drain is generally all your C70 needs.
Engines found in the diesel C70
The version name on the badge tells us which engine your C70 has, so it's worth reading before you phone.
Not knowing which version you have does not need to stop you. Ring all the same, then we'll figure it out with you.
AdBlue in a diesel Volvo C70
AdBlue changes what the capacity of the tank means. With AdBlue in a diesel Volvo C70, the diesel already in your tank does not weaken it. Being mostly water, AdBlue stays separate from the diesel and settles to the bottom, which is where the pump pulls from. Even a tiny amount gets into your fuel line.
As the water in AdBlue dries out, the urea left over crystallises in the lines and the fuel filter and attacks the metalwork next to it, and AdBlue does not combust or give your pump any protection either.
Certain diesel cars carry AdBlue in a separate tank with its own filler, frequently next to the diesel one under the same flap. If your C70 has an AdBlue filler, the diesel nozzle is the larger of the two, and the AdBlue cap is normally blue.
What a fuel drain on your Volvo C70 takes
Done where the car is parked, a fuel drain on your Volvo C70 empties the whole tank, whatever size the tank is on your version. Clean diesel is put in after the tainted fuel is pumped out and the lines and your filter are flushed, and then the system is primed and the motor fired up.
Still at the forecourt or sitting on your driveway, your C70 can be drained just the same. Once we finish this drain, your car is running on clean diesel and ready to drive away.
How AdBlue removal from a diesel Volvo C70 works
AdBlue removal from a diesel Volvo C70 begins with emptying the tank fully, since AdBlue collects at the base instead of blending in. We also flush the lines and the filter through if your engine has run, replacing your fuel filter where it needs changing.
Taking out or switching off the AdBlue system on the vehicle is not what this is about. It's about AdBlue that has gone into your diesel tank.
The cost of a fuel drain on the Volvo C70
We don't give a fixed price, because two call-outs on the same model can be very different. The largest factor is whether anybody has started or driven the C70. Then comes the amount that was put in compared with how large your tank is, which fuel it was, and where the vehicle is at the moment.
With those details, we can explain what this job will need when you ring.
Tank queries about petrol in a diesel Volvo C70
Fuel tank capacity of the Volvo C70: how much does it hold?
From 60 to 62 litres depending on the version, and every version is listed in the table above.
Does a bigger tank make petrol less of a problem?
In a bigger tank, petrol is a smaller share of the whole, yet it has not gone anywhere, and it gets to your pump as soon as your engine runs. With your C70 turned off, a drain removes all of it.
Do you list more than one diesel C70?
We keep data for 5 diesel versions of the C70, and you can pick out yours in the table above from the model name on its badge.
Wrong fuel in my Volvo C70: what does that include?
It means everything put into the diesel tank that's not diesel, so petrol of any type, even super unleaded, or AdBlue, which has its own dedicated tank.
Wherever the Volvo C70 is, can you drain it?
We do. The vehicle doesn't need to be shifted or switched on, as we travel to it whether it is still on the station forecourt or parked at home.
