Ferrari Fuel Drain


Filling up with Diesel in a Petrol Ferrari is a regular error. And its solution depends on various factors. If you would like to know what it is advisable to do to fix it then read on.
Listed below are the key factors to take into account when figuring out whether to get your car drained:

  1. What level of Diesel did you put into the Ferrari, considering that the fuel capacity of the Ferrari 456 GT is in most cases about 110 litres?
    1. A tiny quantity of Diesel, less than 5.5 litres of Diesel in a Petrol 456 GT will in most cases not necessarily be a major problem. Experience has proven to us that quantities under 5.5 litres (which is about 5% of the fuel tank) is often capable of being adequately diluted simply by completely filling the rest of the tank with Petrol.
      It is very unusual to come across a car or truck suffering from problems due to less than 5% incorrect fuel contamination. Remember that it's infrequently found - certainly not impossible to encounter. There are a few automobiles that don't endure any quantity of fuel contamination at all.
    2. Between 5.5 and 11 litres of Diesel in the Ferrari (5 to 10%) is more of a 50/50 scenario. Our practical experience has confirmed that as many people get away with it as those who break down. When you are trying to decide whether or not to risk it and just simply top it up remember that it is the same thing as gambling all of it on black - you've got a 50/50 chance of it being ok.
    3. Anything above 11 litres of Diesel in your Petrol 456 GT really should immediately be removed because your likelihood of driving with this amount of contamination is certainly below one in 50 - definitely big odds.
  2. Put some Diesel in a Petrol Ferrari and drove it: Have you detected any performance issues ever since putting the wrong fuel in the 456 GT? In that case, get it drained irrespective of the quantity of Diesel or even the contamination ratio. Continually running a car that is starting to suffer the effect of fuel contamination can just be responsible for increasing amounts of damage being caused to your fuel system parts.
  3. Are you interested in reassurance?
    In that case get it emptied. No matter the contamination percentage, there is always some degree of risk affiliated with running a Petrol motor on fuel contaminated with Diesel. Possible results of driving on the wrong fuel include the engine refusing to start, running lumpy, reduced power, wearing of the high-pressure pump, worn out or bunged injectors, and so forth. These are some of the most frequently seen Diesel in Petrol symptoms, and in the event that you detect any of them stop and get it removed 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.
