Put Petrol in a Diesel Alfa Romeo 145?
We'd urge you to keep your motor off if you have put petrol in a diesel Alfa Romeo 145 and not started it yet, and that counts for moving it off the forecourt too. Whilst the motor remains off that petrol sits in the tank, so a fuel drain is generally all it needs to set your 145 right.
Your Alfa Romeo 145 can be left wherever it has stopped, forecourt or not, since Petrol in Diesel drains misfuelled vehicles on the spot. We will go through it with you over the phone, so call us before attempting anything yourself.
Got petrol in a diesel 145? What to do first
- Motorists often drive off without realising something is amiss, because a diesel 145 will usually start and run on petrol and may seem normal for the first couple of miles. So keep the engine off.
- Leave the ignition off as well. On a lot of diesels turning it on is enough to set the fuel pump priming, which pulls fuel out of your tank on to your injectors.
- Filling up with diesel to thin it is a mistake, even with super unleaded, which counts as petrol too. The tank on the 145 takes up to 61 litres, and every litre of diesel put in is more tainted fuel for us to empty.
- Forecourt attendants will normally help push your car clear in neutral if it is blocking a pump.
- When the badge gives the precise variant, for example the 145 TD, mention it once you phone 0333 366 0103. Let us know too which 145 you have and where it is parked, roughly how much petrol was put in and whether the engine has been run.
Driven the car with wrong fuel in your Alfa Romeo 145?
While it sits inside your tank, wrong fuel in your Alfa Romeo 145 does not affect the motor. That only begins once it is drawn out, which is what happens when the engine is started. While it runs through, diesel fuel keeps your high-pressure pump and the fuel injectors lubricated, and your engine relies on that. Petrol dilutes the diesel and washes that protection away, which is why it is driving for any distance on that mix that can do harm.
Find somewhere safe to pull in then switch off, if the 145 has already been driven. We drain your tank, then rinse the pipes and filter through till no tainted fuel is left, so it can still be put right. Provided it is cleaned out properly after being caught soon, it very seldom leaves permanent harm.
Checking the Alfa Romeo 145 fuel tank capacity
The size of your tank matters because the danger rests on what share of the fuel in it is petrol, so the same couple of litres are a bigger problem if your tank was close to empty when you filled up.
According to the version, the Alfa Romeo 145 has a tank of 55 to 61 litres.
Our data put the largest tank in the 145 1.9 JTD and the smallest in the 145 TD.
| Version | Fuel tank |
|---|---|
| Alfa Romeo 145 1.9 JTD | 61 litres |
| Alfa Romeo 145 TD | 55 litres |
Which diesel variant of the 145 do you drive?
It helps us to have the version when you phone, and it is normally on a badge at the back of your car.
On a diesel 145 you can see JTD and TD on the badging.
Each variant in our records has an engine of 1.9 litres.
AdBlue in a diesel Alfa Romeo 145 by mistake
Some diesel cars carry a mix of water and urea, known as AdBlue, in a tank of its own with a dedicated filler, and rely on it to treat their exhaust. Even to move your car, don't touch the key when you've got AdBlue in a diesel Alfa Romeo 145 after it went into the wrong filler.
The fuel pump has no lubrication at all from AdBlue, which is mainly water and won't burn. It won't mix with diesel either, and sinks to the base of your tank, the same location your pump draws from, so a tank holding up to 61 litres does nothing to dilute it.
A modest quantity is still drawn into the fuel system. When the water dries off, the urea forms crystals inside the fuel system, including the filter and injectors, and it eats into the metal it sits against.
Where your 145 has an AdBlue filler, it could well lie beside the diesel filler under the same flap, as it does on a lot of motors. You can typically spot the AdBlue cap by its blue shade and the much narrower nozzle it takes.
How a fuel drain on your Alfa Romeo 145 works
Every fuel drain on your Alfa Romeo 145 is done beside your vehicle, and it doesn't need to go to a garage. Before we start the motor, the system is primed and the tank filled up with clean diesel. First comes checking what was put in and whether it has run, emptying a tank that takes up to 61 litres on the 145, and flushing the lines and fuel filter.
When we have finished, the 145 runs on fresh diesel and you can drive off in it.
Handling AdBlue removal from a diesel Alfa Romeo 145
We follow the same stages for AdBlue removal from a diesel Alfa Romeo 145 as we do for emptying petrol. We flush crystals out of the pipes too when the 145 has been run, and change your fuel filter where needed, because AdBlue collects in the bottom of your tank instead of mixing in and may leave them there.
AdBlue removal, as we use the term here, is about AdBlue that went in the incorrect filler and has to come out of the diesel tank. It doesn't cover removing or disabling the AdBlue system on your vehicle.
A fuel drain on the Alfa Romeo 145: what it costs
As every job is different, we have no fixed price to publish, and these are the main factors that affect it:
- whether anybody has started or driven the 145, the thing that matters most
- the amount put in, weighed against the size of the tank
- whether it was AdBlue rather than petrol
- whether the van can easily and safely reach the 145 where it sits
With those details over the phone, we can let you know what the job is going to involve.
Your queries on petrol in a diesel Alfa Romeo 145
How many litres is the Alfa Romeo 145 fuel tank capacity?
The table further up lists every version, with tanks of between 55 and 61 litres.
Does topping up with diesel help with a little petrol in my 145?
We wouldn't recommend it. Adding diesel lowers the share of petrol without taking out any of that, so the petrol is still in your system when you drive. The 145 normally needs nothing more than a drain if just a small amount was put in, and that gets that petrol out entirely.
Must my 145 go to the Alfa Romeo dealer?
You do not need to. We have no connection with Alfa Romeo or any of its dealers, being independent, and your 145 is drained and cleaned where you have stopped.
Does the variant of my 145 matter?
We hold figures for 2 diesel versions of the 145, and knowing which one you have helps us when you phone.
Is wrong fuel in my Alfa Romeo 145 covered by my insurance policy?
It is worth checking your policy, as misfuelling cover is included in some and not others. Whichever way it reads, we come out and drain the car.
What if I pour diesel in the AdBlue tank of my 145?
Keep the key out of the ignition in that case as well. The majority of motors show a warning and go into limp mode if they are driven in that state, and the AdBlue system will need draining. When you ring, tell us which tank the diesel went into.
I drove my 145 before I noticed. What do I do?
Stop where it is safe and switch your motor off, then keep it off till we get to you. Wherever you have pulled over, the fuel system is emptied and cleaned there, and caught soon like this, it very rarely leaves long-term damage.
