Alfa Romeo Fuel Drain


Putting Petrol in a Diesel Alfa Romeo is a well-known mistake to make. And exactly what you need to do about it is dependent upon a variety of things. If perhaps you would like to know what you should do to fix it then keep on reading.
Listed here are the key variables to to consider whenever deciding whether or not to have it drained:

  1. How much Petrol have you put in the Alfa Romeo, taking into account that the fuel capacity of the Alfa Romeo 156 JTD is normally approximately 63 litres?
    1. A tiny amount of Petrol, as little as 3.15 litres of Petrol in a Diesel 156 JTD will most of the time not be a major problem. Experience has demonstrated to us that an amount less than 3.15 litres (which is about 5% of the total fuel tank capacity) is frequently capable of being sufficiently diluted simply by thoroughly filling up the tank with the appropriate fuel.
      It is highly uncommon to come across a car experiencing difficulties with less than 5% incorrect fuel contamination. Keep in mind it's unusual - in no way impossible to find. You will discover certain vehicles that will not stand any amount of contamination whatsoever.
    2. In between 3.15 and 6.3 litres of Petrol in the Alfa Romeo (5 to 10%) is really a 50/50 situation. Our experience has shown us that as many motorists get away with it as those people who don't. Any time you're figuring out whether or not to risk it and just simply top it up bear in mind that it is the same thing as gambling it all on black - you have a 50/50 chance of it working.
    3. Anything above 6.3 litres of Petrol in a Diesel 156 JTD should promptly be drained out as your probability of succeeding with that quantity of contamination is certainly less than one in 50 - genuinely huge odds.
  2. Put Petrol in a Diesel Alfa Romeo and drove it: Have you detected any performance troubles after putting the incorrect fuel in your 156 JTD? If that's the case, get it emptied irrespective of the volume of Petrol or even the contamination percentage. Still running an automobile that is now beginning to suffer from the effects of wrong fuel contamination will definitely lead to more harm affecting the fuel system components.
  3. Are you interested in peace of mind?
    Simply get it removed. Regardless of the contamination ratio, there is always a certain level of risk connected to running a Diesel engine on fuel contaminated with Petrol. Possible results of driving on the wrong fuel include things like the motor refusing to start, running lumpy, losing power, degradation of the high-pressure pump, worn or blocked injectors, and so on. These are a few of the commonest Petrol in Diesel signs or symptoms, and if you recognise any of them cease driving and have it drained asap.

Petrol in Diesel Questions

When someone has put Petrol in a Diesel car they have a few very common questions. So we have compiled a list of the most Frequently Asked Questions for you

I put Petrol in a Diesel car and drove it. What do I do?


Turn off the car as soon as possible and call us. Continuing to run a vehicle on the wrong fuel can potentially damage it. We will be able to give you advice and assistance based on your circumstances

Will driving a Diesel car on Petrol cause damage to it?


It can. However, if the problem is caught and remedied quickly the risks will be minimal. Of the 1,500 vehicles we attend every month, less than 0.5% have suffered and substantial damage requiring parts replacement.

How much Petrol can I get away with in a Diesel car?


The safe answer is none. However you might be able to get away with a very low contamination ratio. That being said, we always highly recommend draining anything over a 5% contamination ratio asap.

I know about petrol in diesel, but what about Super Unleaded?


Putting Super Unleaded, or Shell V-Power, BP Ultimate Unleaded, etc, will have the exact same effect as putting regular unleaded petrol in your diesel car and will need to be drained out and flushed.

Will getting you to do a fuel drain void my warranty?


No! The EU Block Exemption Regulations clearly state that "the work can be carried out by as long as that garage uses manufacturer approved parts and correctly follows the manufacturer's service schedule."

Can I top it up with Diesel and add some 2-stroke oil?


This might work on some vehicles in some cases, but in the majority on instances it won't and you risk damaging the Lambda sensors as well as fuel pump and injectors, just as a regular misfuel.
