What the Tank Holds: Petrol in a Diesel Rover 75
Someone who has got petrol in a diesel Rover 75 needs to find out the size of its fuel tank early on, since that determines how much of the fuel in there is now petrol. Our guide lists the tank on each version of the Rover 75 we hold data for, plus the motors it came with.
Regardless of how big the number is, there is one thing to do after the mistake. Leave your engine off then phone Petrol in Diesel, after which we'll come over and drain the vehicle where it sits.

|---|---|
| Rover 75 2.0 CDT | 65 litres |

Does a small quantity of wrong fuel in your Rover 75 matter?
The share of petrol depends on how full your tank was before you filled up. That is because wrong fuel in your Rover 75 blends with whatever diesel was still in it. Up to 65 litres go into your tank. Topping up an almost full one with a couple of litres of unleaded means only a small share of petrol in the whole, while the same amount in an almost empty tank is far more of what the engine would take in.
Drivers often wonder how much petrol is too much. Whether the engine has been run is the more helpful point to find out. After it runs, your pump draws that blend from the tank and pushes it on to the fuel injectors.
A fuel drain is the safe course whatever the share, and with a small quantity it is normally all your 75 needs.
Which engines your diesel 75 came with
Before you phone, it's worth reading the version name on the badge, since it shows us which engine your 75 has.
Across the diesel 75 versions in our figures, the badges read CDTI.
All of them use the same engine size, 2.0 litres.
There are Tourer 75 versions in the figures as well.
If you are not certain which version you have, call all the same and we will work it out with you.
What goes on with AdBlue in a diesel Rover 75
With AdBlue, tank size works differently. The fuel pump takes its fuel from the base of the tank, and that's where AdBlue settles, and so even a small amount gets into the fuel line. If you have got AdBlue in a diesel Rover 75, the diesel surrounding it doesn't dilute it, since AdBlue is mainly water and doesn't blend with diesel.
AdBlue gives your pump no lubrication and will not combust. Its water dries out as it sits, leaving urea that forms crystals in the filter and your lines, where it eats into the metalwork it touches.
The filler for AdBlue, on diesel vehicles that have it, frequently shares a flap with the diesel one and leads to a second tank. If your 75 has one, the AdBlue cap is generally blue and takes a narrower pump nozzle than the diesel one.
A fuel drain on your Rover 75, step by step
A fuel drain on your Rover 75 clears the entire tank, whatever its size in your version, and it is done where your car is standing. Clean diesel goes in after the tainted fuel gets pumped out and the lines and your filter are cleaned, and then your system is primed and your engine started.
Still on the station forecourt or sitting on your driveway, your 75 can be emptied just the same. After we finish this drain, the vehicle is running on fresh diesel and ready to drive away.
AdBlue removal from a diesel Rover 75, explained
Emptying the tank totally is how AdBlue removal from a diesel Rover 75 starts, as AdBlue does not blend in and settles at the bottom instead. An engine that has been started means cleaning your filter and lines through too, plus changing your fuel filter if needed.
Removing or turning off the AdBlue system on your car isn't what this covers. It's about AdBlue that has got into the diesel tank.
Pricing a fuel drain on the Rover 75
There is no fixed price listed here, because call-outs on one model can differ quite a lot. The biggest factor is whether anyone has started or driven the 75. Then comes the amount that went in against how big the tank is, which liquid it was, and where your car is now.
Phone with those details and we can tell you what the job will involve.
Your tank questions on petrol in a diesel Rover 75
Fuel tank capacity of the Rover 75: how much does it hold?
65 litres, with every version we hold data for using the same tank.
Does petrol matter less in a bigger tank?
A bigger tank means a few litres form less of the whole, yet the petrol is still in there and still gets to your pump when your engine runs. A fuel drain clears all of that as long as your 75 stays switched off.
How many versions of your diesel 75 are in your data?
Your boot badge tells you which of the 4 diesel versions of the 75 in the table above is yours, as we hold figures for each.

Only diesel belongs in the diesel tank. Petrol of every grade, super unleaded included, is wrong fuel, and so is AdBlue, which goes in a tank of its own.
Wherever the Rover 75 is, can you drain the vehicle?
We do. The vehicle does not need to be moved or started, as we travel to it whether it's still on the station forecourt or left on your drive.
