Ferrari Fuel Drain


Putting Diesel in a Petrol Ferrari is a usual problem. And its remedy hinges on an assortment of things. If you would like to know what you have to do to fix it then read on.
These are the main variables to take into account when choosing whether to have a fuel drain:

  1. How much Diesel did you put into the Ferrari, keeping in mind that the fuel capacity of your Ferrari 599 GTB Fiorano is usually about 105 litres?
    1. A modest amount of Diesel, less than 5.25 litres of Diesel in a Petrol 599 GTB Fiorano will in most situations not be a huge problem. Experience has proven to us that quantities under 5.25 litres (close to 5% of the entire fuel tank capacity) is very often able to be completely diluted by completely filling up the remainder of the tank with Petrol.
      It is quite uncommon to find an automobile going through problems due to under 5% incorrect fuel contamination. Bear in mind that it is very unusual - not impossible to encounter. There are a number of cars that will not endure any amount of fuel contamination whatsoever.
    2. Somewhere between 5.25 and 10.5 litres of Diesel in the Ferrari (from 5 to 10%) is more of a 50/50 scenario. Our practical experience has demonstrated that as many motorists get away with this as all those who don't. Any time you're deciding upon whether or not to risk it and basically top it up recognise that it is just like betting all of it on black - you've got a 50/50 possibility of it working out.
    3. Anything above 10.5 litres of Diesel in a Petrol 599 GTB Fiorano should straight away be drained seeing as your probability of driving with this level of contamination is almost certainly lower than one in fifty - truly big odds.
  2. Put some Diesel in a Petrol Ferrari and drove it: Have you noted any performance difficulties ever since putting the bad fuel in the 599 GTB Fiorano? If you have, have it emptied regardless of the amount of Diesel or the contamination percentage. Continually running an automobile that is beginning to suffer from the effects of fuel contamination will probably only be responsible for more harm affecting the fuel system.
  3. Do you want security?
    You should get it drained. Regardless of contamination percentage, there is always some amount of risk connected to operating a Petrol engine on Petrol contaminated with the incorrect fuel. Likely final outcomes of driving a vehicle on the wrong fuel can include the motor not starting, running unevenly, losing power, wearing of the high-pressure pump, worn or blocked injectors, and the like. These are a few of the commonest Diesel in Petrol signs and symptoms, and if you notice any of them then stop and get it removed 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.
