Ferrari Fuel Drain


Filling up with Diesel in a Petrol Ferrari is a regular mistake to make. And its solution is based on several things. In case you want to find out what it is advisable to do about this then keep on reading.
These are the main factors to keep in mind whenever deciding on whether to get a fuel drain:

  1. Exactly how much Diesel have you put in the Ferrari, taking into account that the fuel tank capacity of your Ferrari F50 is in most cases about 105 litres?
    1. Hardly any Diesel, as little as 5.25 litres of Diesel in a Petrol F50 will normally not necessarily be a massive problem. Experience has proven to us that an amount less than 5.25 litres (almost 5% of the whole fuel tank) is usually able to be sufficiently diluted simply by wholly filling the rest of the tank with Petrol.
      It's quite unusual to come across a vehicle suffering from issues because of under 5% wrong fuel contamination. Keep in mind it's infrequently found - definitely not impossible to encounter. There are actually a number of motor vehicles that won't endure any quantity of contamination at all.
    2. Somewhere between 5.25 and 10.5 litres of Diesel in the Ferrari (5 to 10%) is more of a 50/50 scenario. Our expertise has confirmed that as many people get away with this as those people who break down. Any time you are figuring out whether to risk it and just simply fill it up recognise that it is exactly like wagering everything on black - you have got a 50/50 chance of it working out.
    3. Anything over 10.5 litres of Diesel in your Petrol F50 really should right away be drained as your probability of driving with this level of contamination is certainly lower than one in 50 - genuinely huge odds.
  2. Put Diesel in a Petrol Ferrari and drove it: Have you noticed any performance issues since putting the bad fuel in your F50? If so, get it drained no matter the quantity of Diesel or even the contamination percentage. Continually driving an automobile that is now beginning to suffer from the effects of fuel contamination will likely bring about even more damage affecting the fuel system parts.
  3. Are you interested in peace of mind?
    Simply get it emptied. Whatever the contamination percentage, there is inevitably some degree of risk resulting from driving a Petrol engine on fuel contaminated with Diesel. Possible outcomes of driving on the incorrect fuel include the motor not starting, running lumpy, lack of power, wearing of the high-pressure pump, worn out or clogged injectors, and so on. These are several of the commonest Diesel in Petrol signs or symptoms, and should you observe any of them stop and get it drained 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.
