Ferrari Fuel Drain


Filling up with Diesel in a Petrol Ferrari is a common error. And its remedy hinges on various things. If you would like to find out what to do to sort it out then keep reading.
Here are the most important variables to be aware of whenever deciding on whether or not to have a fuel drain:

  1. What level of Diesel did you put in to the Ferrari, keeping in mind that the fuel tank capacity of the Ferrari F12 Berlinetta is probably approximately 92 litres?
    1. A modest amount of Diesel, as little as 4.6 litres of Diesel in a Petrol F12 Berlinetta will generally not necessarily be a significant problem. Experience has demonstrated to us that quantities less than 4.6 litres (almost 5% of the total fuel tank capacity) is frequently able to be sufficiently diluted simply by completely topping the remainder of the tank with the correct fuel.
      It is pretty uncommon to find a car having difficulties due to less than 5% incorrect fuel contamination. Do not forget that it is very infrequent - in no way impossible to find. You can get certain cars that won't stand any quantity of fuel contamination at all.
    2. Between 4.6 and 9.2 litres of Diesel in the Ferrari (from 5 to 10%) is really a 50/50 condition. Our practical experience has demonstrated that as many people get away with this as those who break down. When trying to decide whether or not to chance it and simply fill it up bear in mind that it is much like wagering it all on black - you've got a 50/50 possibility of it working.
    3. Anything more than 9.2 litres of Diesel in your Petrol F12 Berlinetta should straight away be removed seeing as your likelihood of driving with this amount of contamination is probably below one in 50 - really long odds.
  2. Put some Diesel in a Petrol Ferrari and drove it: Have you observed any performance concerns ever since putting the bad fuel in your F12 Berlinetta? If you have, have it removed regardless of the amount of Diesel or even the contamination percentage. Proceeding to run driving a vehicle that is already beginning to suffer from the consequences of fuel contamination can definitely result in increasing amounts of damage affecting the fuel system components.
  3. Would you like security?
    Then get it removed. Regardless of the contamination percentage, there is inevitably some extent of risk caused by driving a Petrol engine on Petrol contaminated with Diesel. Possible final outcomes of driving on the incorrect fuel can include the motor refusing to start, running lumpy, decrease in power, degradation of the high-pressure pump, damaged or blocked injectors, and so on. These are several of the commonest Diesel in Petrol signs and symptoms, and in the event that you recognise any of them stop driving and get it drained immediately.

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.
