Tank Sizes for Petrol in a Diesel Alfa Romeo
Anyone who has got petrol in a diesel Alfa Romeo wants to check the size of the fuel tank on their model, since that settles how much petrol is currently in that mixture. This page lists the tank sizes throughout the diesel Alfa Romeo range, and each model has a page of its own, listed further down.
Petrol in Diesel drains the vehicle where it is, however large the tank is, so the advice is to keep your engine turned off then phone us as soon as you know what has happened.
How big the fuel tanks are in the diesel Alfa Romeo range
The smallest tank in the diesel Alfa Romeo range holds 45 litres and the largest takes 72, and where yours sits depends on the model and version.
Up to 61 litres fits into the fuel tank of the 146.
In our data, the fuel tank on the 147 takes 60 litres at the most.
Each model page lists the fuel tank for every version of that model, with 39 variants split among the 12 diesel Alfa Romeo models we cover.
Wrong fuel in your Alfa Romeo: what a couple of litres amounts to
Wrong fuel in your Alfa Romeo mixes with whatever diesel was still inside the tank, so the share that is petrol hinges on how full it was when you filled up. Tanks in the range take up to 72 litres, so filling a tank that's almost full with a couple of litres of petrol means the petrol just a small share of the whole, whereas the same few litres in an almost empty tank are a far bigger part of what reaches the engine.
Motorists commonly wonder how much petrol is too much. Running the engine is what moves the blend from your tank and through the fuel pump and the injectors, so the more helpful thing to find out is whether it's run.
With a modest amount, emptying your tank is normally enough.
Engine options in the diesel Alfa Romeo range
Diesel Alfa Romeo cars within our data have JTDM, JTD, Multijet and TD badges.
The smallest unit in the range is 1.3 litres and the largest is 2.4 litres.
We can work out which one you have from the model name and the badging on the back, so look at them before you phone. Call even when you are not sure, as we'll figure it out with you on the phone.
What goes on with AdBlue in a diesel Alfa Romeo
Where AdBlue is concerned, the size of the tank does not help. If you have got AdBlue in a diesel Alfa Romeo, the diesel around it can't thin it, because AdBlue is mostly water and does not blend with diesel. It sinks to the bottom of the tank, where the fuel pump pulls from, so even a tiny quantity gets into the fuel lines.
AdBlue gives the fuel pump no lubrication and will not burn. Its water evaporates as it stands, leaving urea that crystallises in the filter and the lines.
Under the same flap as the diesel filler there is often a second one for AdBlue, with a blue filler cap and a smaller nozzle, where your vehicle has a separate AdBlue tank.
How a fuel drain on your Alfa Romeo works
However big the tank is on your car, a fuel drain on your Alfa Romeo empties all of that, right where the car is sitting. We draw out the tainted fuel, flush the lines and the filter, and refill with fresh diesel before priming the fuel system and starting your engine.
With the GT, that tank holds up to 63 litres.
When we finish this drain, the car is ready to drive away on fresh diesel.
AdBlue removal from a diesel Alfa Romeo
AdBlue settles at the bottom of your tank instead of blending in, so draining it entirely is the opening stage of AdBlue removal from a diesel Alfa Romeo. If the engine has run, we rinse the lines and your filter through as well and change the filter where needed.
What this covers is AdBlue that has ended up in the diesel tank, not taking out or disabling the AdBlue system on the vehicle.
How the price of a fuel drain on a diesel Alfa Romeo is set
Two call-outs on the same model can be quite different, so we don't list a fixed price. How much was put in compared with the size of the tank, whether it was petrol or AdBlue, and where the car is now all count, yet whether your car has been driven or only started affects it most. Those facts are what we need to explain what this work involves. Call with them ready.
Your tank queries on petrol in a diesel Alfa Romeo
Which Alfa Romeo diesel takes the most fuel?
Up to 72 litres fits into the tank on the 166, the biggest in our data, and the smallest is on the Mito.
Does a larger tank make petrol less of a problem?
A larger tank means a few litres form less of the total, yet the petrol is still in there and still gets to the pump once the engine runs. With the vehicle turned off, a fuel drain removes all of that.
My exact version: where is its tank size listed?
Every model has a page of its own, linked further down, and the one for your model lists each version in our data, along with its tank.
What counts as wrong fuel in my Alfa Romeo?
Only diesel belongs in the diesel tank. Petrol of any grade, super unleaded too, is wrong fuel, and so is AdBlue, which goes in a tank of its own.
