Alfa Romeo Fuel Drain


Filling Diesel in a Petrol Alfa Romeo is a common mistake. And what you should do about it varies according to a variety of things. In case you want to know what it is advisable to do about this then stay with me.
These are the most crucial variables to to consider when deciding whether to get your car drained:

  1. How much Diesel did you put in the Alfa Romeo, considering that the fuel tank capacity of the Alfa Romeo 156 is most likely approximately 63 litres?
    1. A small amount of Diesel, less than 3.15 litres of Diesel in a Petrol 156 will usually not really be a huge problem. Experience has demonstrated to us that an amount under 3.15 litres (which is about 5% of the whole fuel tank capacity) is usually capable of being completely diluted simply by totally filling up the tank with the right fuel.
      It is pretty unusual to encounter a car or truck experiencing difficulties because of less than 5% wrong fuel contamination. Be aware that it is very unusual - not impossible to find. You can get some vehicles that don't stand any amount of contamination in the slightest.
    2. Anywhere between 3.15 and 6.3 litres of Diesel in the Alfa Romeo (from 5 to 10%) is more of a 50/50 scenario. Our practical experience has confirmed that as many drivers get away with this as those who don't. Any time you are figuring out whether or not to risk it and basically fill it up recognise that it is very much like gambling all of it on black - you've got a 50/50 possibility of it working out.
    3. Anything over 6.3 litres of Diesel in a Petrol 156 really should immediately be removed since your likelihood of driving with that level of contamination is probably less than one in 50 - truly big odds.
  2. Put Diesel in a Petrol Alfa Romeo and drove it: Have you noted any performance concerns since putting the bad fuel in your 156? If you have, get it emptied regardless of the volume of Diesel or the contamination ratio. Continuing to run running an automobile that is now beginning to suffer from the effects of wrong fuel contamination can just result in even more harm being caused to the fuel system parts.
  3. Do you need reassurance?
    You should get it emptied. Regardless of contamination ratio, there is invariably a certain level of threat linked with operating a Petrol vehicle on fuel contaminated with Diesel. Probable implications of driving on the incorrect fuel include the motor not starting, running unevenly, lack of power, degradation of the high-pressure pump, worn or bunged injectors, and the like. These are a few of the most common Diesel in Petrol signs and symptoms, and in the event that you observe any of them then cease driving and get it drained right now.

Diesel in Petrol FAQs

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

I put Diesel in a Petrol 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 Petrol car on Diesel 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 Diesel can I get away with in a Petrol 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 Petrol 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.
