Alfa Romeo Fuel Drain


Putting Petrol in a Diesel Alfa Romeo is a regularly occurring error. And its remedy will depend on several factors. Assuming you want to know what it is best to do about this then please read on.
Let us discuss the most crucial variables to take into consideration whenever choosing whether to have the car drained:

  1. Exactly how much Petrol have you put in to the Alfa Romeo, taking into account that the fuel tank capacity of the Alfa Romeo 146 TD is normally roughly 51 litres?
    1. A modest quantity of Petrol, less than 2.55 litres of Petrol in a Diesel 146 TD will normally not really be a significant problem. Experience has taught us that an amount under 2.55 litres (5% of the entire fuel tank capacity) is oftentimes able to be sufficiently diluted through entirely filling up the rest of the tank with Diesel.
      It's rather rare to find a car or truck going through problems because of below 5% wrong fuel contamination. Please remember it is infrequent - certainly not impossible to encounter. You can get certain motor vehicles that will not stand any level of contamination at all.
    2. In between 2.55 and 5.1 litres of Petrol in the Alfa Romeo (5 to 10%) is really a 50/50 scenario. Our practical experience has confirmed that as many motorists get away with it as all those who break down. When trying to decide whether or not to chance it and just simply top it up bear in mind that it is the same thing as wagering it all on black - you will have a 50/50 chance of it being ok.
    3. Anything above 5.1 litres of Petrol in a Diesel 146 TD should right away be drained out as your likelihood of succeeding with this quantity of contamination is probably less than one in fifty - genuinely long odds.
  2. Put Petrol in a Diesel Alfa Romeo and drove it: Have you observed any performance problems after putting the bad fuel in the 146 TD? If you have, get it emptied regardless of the amount of Petrol or the contamination percentage. Proceeding to drive driving an automobile that is now beginning to suffer the consequences of wrong fuel contamination will probably typically result in more and more harm being done to your fuel system parts.
  3. Are you looking for peace of mind?
    You should get it drained. Whatever the contamination percentage, there is always some amount of danger connected with driving a Diesel motor on fuel contaminated with Petrol. Probable consequences of driving on the incorrect fuel include the motor refusing to start, running lumpy, reduced power, wearing of the high-pressure pump, worn or blocked injectors, etc. These are a few of the most typical Petrol in Diesel warning signs, and should you detect any of them stop and get it removed immediately.

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.
