Petrol in a Diesel Infiniti FX: What the Tank Holds
How much petrol there now is in the blend rests on the tank, so its size is worth finding out early on when you've put petrol in a diesel Infiniti FX. The tank and the engines are set out here for every Infiniti FX version that we keep figures for.
Whatever the size, the guidance is no different now that it has happened. With your engine kept off, ring Petrol in Diesel and the car can be drained where it is.
The Infiniti FX fuel tank capacity for every version
Every version of the Infiniti FX in our figures shares the same diesel tank, which holds 90 litres.
Wrong fuel in your Infiniti FX: what a few litres amounts to
Wrong fuel in your Infiniti FX mixes with whatever diesel is already inside the tank, so the share of your fuel that is petrol hinges on how full your tank was when you refuelled. When a few litres of unleaded are put into a tank running near empty, they make up a far bigger share of what your engine would take in. Added to a nearly full tank of up to 90 litres, the same volume is just a small share of the whole.
The quantity of petrol that is too much is something drivers frequently wonder about. The more useful point to check is whether your engine has run, since running it is what moves the blend from the tank and through your pump and your injectors.
A drain is the right course no matter what the share, and with a modest volume it's usually all your FX needs.
Engines used in the diesel FX
Before you call, it's worth reading the version name on the badge, as it tells us which motor your FX has.
Once you ring, we can figure out which version it is together, even when you are not certain of it yourself.
AdBlue in a diesel Infiniti FX
With AdBlue, tank size works differently. If you have got AdBlue in a diesel Infiniti FX, the diesel around it does not thin it, as AdBlue is mainly water and doesn't blend with diesel. It settles to the bottom of your tank, which is where the fuel pump draws from, so even a tiny quantity gets into the fuel lines.
As the water in AdBlue evaporates, the urea left over crystallises in the fuel lines and the filter and eats into the metal around it, and AdBlue does not burn or give your pump any lubrication either.
A second tank with a dedicated filler holds the AdBlue on certain diesel cars, often next to the diesel filler under the same flap. Where your FX has an AdBlue filler, its filler cap is usually blue and accepts a narrower nozzle than the diesel one.
Fuel drain on your Infiniti FX
Whatever size the tank is on your version, a fuel drain on your Infiniti FX clears all of that, right where your car is sitting. We pump the tainted fuel out, flush the lines and the fuel filter, and refill with fresh diesel ahead of re-priming the fuel system and starting your engine.
It doesn't matter whether your FX is still at the forecourt or left on your driveway. Once this drain is finished it's running on fresh diesel and you can drive it away.
What AdBlue removal from a diesel Infiniti FX takes
AdBlue removal from a diesel Infiniti FX begins with emptying the tank entirely, because AdBlue settles at the bottom rather than blending in. Where the engine has been run, the lines and the filter are purged through too, and the filter is replaced if necessary.
This is about AdBlue that has got into the diesel tank. It is not taking out or disabling the AdBlue system on your car.
How the quote of a fuel drain on the Infiniti FX is worked out
There is no fixed price listed here, since jobs on one model can vary quite a lot. The biggest factor is whether anyone has started or driven the FX. Then comes the amount that got in compared with how large your tank is, what fuel it was, and where the vehicle is at the moment.
Ring with those facts and we can explain what the job will involve.
Tank questions about petrol in a diesel Infiniti FX
What does the Infiniti FX fuel tank capacity come to?
90 litres, with each version we hold data for using the same tank.
Does petrol matter less with a bigger tank?
That petrol is still there in a larger tank, and still gets to your pump as soon as the motor runs, even though a couple of litres form less of the whole. All of it comes out with a drain, as long as your FX is turned off.
Which fuels, other than diesel, would be wrong fuel in my Infiniti FX?
It means anything put into the diesel tank that's not diesel, and so petrol of every type, including super unleaded, or AdBlue, which has its own dedicated tank.
Will you drain the Infiniti FX where it is?
Yes, wherever it is. Parked at home or still at the pumps, the car remains where it is and isn't started, because we come to it.
