What the Tank Holds: Petrol in a Diesel Ford Grand C-Max
Once you have got petrol in a diesel Ford Grand C-Max, the capacity of its tank is one of the earliest things to know, because it settles how much of the fuel in there is currently petrol. Each version of the Ford Grand C-Max we have data for is on this page with its fuel tank size, and the same goes for the engines it was sold with.
The guidance does not vary with the figure after it has occurred. Phone Petrol in Diesel with the engine kept off. We'll come out to you and drain it right where it stands.
Version by version: Ford Grand C-Max fuel tank capacity
The Ford Grand C-Max has the one diesel tank across every version we hold data for, and it takes 60 litres.
| Version | Fuel tank |
|---|---|
| Ford Grand C-Max 1.6 TDCi | 60 litres |
| Ford Grand C-Max 2.0 TDCi | 60 litres |
Wrong fuel in your Ford Grand C-Max: what a few litres means
Wrong fuel in your Ford Grand C-Max mixes with whatever diesel is still in the tank, and so the part of it that's petrol hinges on how full the tank was when you refuelled. How much petrol gets to the engine depends a lot on the amount inside the tank. The tank holds up to 60 litres, and in an almost full one a few litres stay a small share of the whole, but in a tank sitting close to empty the same few litres become a far greater share.
People commonly want to know how much petrol counts as too much. The more useful thing to find out is whether the engine has been run, as starting it is what moves the blend out of your tank and through your pump and your injectors.
Getting it emptied is the safe option whatever the proportion is. When the amount is small, your Grand C-Max generally needs no more than that.
Engines found in your diesel Grand C-Max
Before you call, it is worth reading the version name on the badge, since it tells us which motor your Grand C-Max has.
Our figures list TDCi badges on the diesel versions of the Grand C-Max.
The engines run from 1.6 litres on the Grand C-Max 1.6 TDCi up to 2.0 litres in the Grand C-Max 2.0 TDCi.
Phone anyway if you're not sure which version you own, then we will figure it out with you.
Fuel tank size and AdBlue in a diesel Ford Grand C-Max
Tank size works differently with AdBlue. AdBlue is mostly water and doesn't mix with diesel, so with AdBlue in a diesel Ford Grand C-Max, the diesel around it does nothing to thin it. Since it settles to the base of the tank, where the fuel pump draws from, even a small volume gets into your fuel line.
AdBlue doesn't burn and gives your pump no protection, and as its water dries out, the urea left behind crystallises in the fuel lines and your filter and corrodes the metal next to it.
Certain diesel vehicles carry AdBlue in a second tank with a dedicated filler, often alongside the diesel filler under the same fuel flap. On any Grand C-Max with an AdBlue filler, a blue cap normally marks it, and that cap fits a smaller pump nozzle than the diesel one.
Fuel drain on your Ford Grand C-Max
The entire tank is emptied in a fuel drain on your Ford Grand C-Max, however large it is in your version, without your car being moved from where it sits. We draw the tainted fuel out, rinse the fuel lines and your filter, and refill with fresh diesel before priming your system and firing up the motor.
Left at home or still at the pumps, your Grand C-Max gets the same drain. Once the drain is complete it's running on clean diesel and you can drive it away.
What AdBlue removal from a diesel Ford Grand C-Max involves
Emptying your tank fully is where AdBlue removal from a diesel Ford Grand C-Max starts, since AdBlue doesn't blend in and collects at the base instead. An engine that has been run means flushing your filter and lines through too, and replacing the fuel filter if it needs it.
This is about AdBlue that has gone into the diesel tank. It is not taking out or disabling the AdBlue system on your car.
The cost of a fuel drain on the Ford Grand C-Max
We do not publish a fixed price, because two jobs on the same model can be rather dissimilar. Whether the Grand C-Max has been run or driven affects it most. After that it rests on how much went in against the tank size, whether petrol or AdBlue got in, and your car's location.
With those facts, we can explain what the job will need when you call.

What is the fuel tank capacity of the Ford Grand C-Max?
Every version we have data for uses one tank, and it holds 60 litres.

Less of the total is petrol if a few litres go into a bigger tank, but it's still there, and running your engine still takes it to the pump. A fuel drain removes all of it while your Grand C-Max stays switched off.
Do you list more than one diesel Grand C-Max?
Your boot badge shows which of the 2 diesel versions of the Grand C-Max in the table above is yours, since we have data for each.
Wrong fuel in my Ford Grand C-Max: what does that cover?
Everything except diesel in your diesel tank, which means petrol of every type, super unleaded as well, or AdBlue intended for its own separate tank.
Will you drain the Ford Grand C-Max where it is?
Yes, wherever it is. Parked at home or still at the pump, your car stays where it is and isn't started, because we travel to it.
