Alfa Romeo Fuel Drain


Filling Diesel in a Petrol Alfa Romeo is a common error. And its remedy is determined by a variety of factors. In case you want to know what you need to do to sort it out then read on.
Right here are the main factors to keep in mind whenever deciding whether or not to have it drained:

  1. Exactly how much Diesel did you put into the Alfa Romeo, bearing in mind that the fuel tank capacity of your Alfa Romeo 155 is probably around 63 litres?
    1. A small quantity of Diesel, as little as 3.15 litres of Diesel in a Petrol 155 will quite often not be a major problem. Experience has shown us that quantities under 3.15 litres (which is close to 5% of the entire fuel tank) is sometimes capable of being completely diluted simply by thoroughly filling the remainder of the tank with Petrol.
      It's highly uncommon to come across a car or truck going through problems with lower than 5% wrong fuel contamination. Keep in mind that it is very infrequent - not impossible to find. You can get some motor vehicles that don't endure any degree of contamination at all.
    2. In between 3.15 and 6.3 litres of Diesel in the Alfa Romeo (5 to 10%) is a 50/50 scenario. Our working experience has shown us that as many people get away with this as those people who break down. When figuring out whether to risk it and basically top it up consider that it is exactly like wagering it all on black - you will have a 50/50 chance of it working.
    3. Anything in excess of 6.3 litres of Diesel in your Petrol 155 really should as soon as possible be removed as your probability of getting away with this level of contamination is very likely less than one in fifty - really big odds.
  2. Put Diesel in a Petrol Alfa Romeo and drove it: Have you noticed any performance problems ever since putting the wrong fuel in your 155? In that case, have it emptied irrespective of the volume of Diesel or the contamination ratio. Continuing to drive running a motor vehicle that is now starting to suffer from the effects of wrong fuel contamination can likely bring about more harm affecting your fuel system.
  3. Would you like reassurance?
    You should get it drained. Regardless of the contamination percentage, there is always a certain level of risk connected to running a Petrol engine on Petrol contaminated with the wrong fuel. Likely outcomes of driving on the incorrect fuel include the motor not starting, running unevenly, reduced power, wearing of the high-pressure pump, worn out or clogged injectors, and so on. These are a few of the most common Diesel in Petrol signs and symptoms, and should you notice any of them then stop and get it removed immediately.

Diesel in Petrol Questions

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.
