Maserati Fuel Drain


Filling up with Petrol in a Diesel Maserati is a fairly typical mistake. And its solution varies according to several different factors. If you would like to find out what you ought to do about this then keep on reading.
Here are the most crucial factors to to consider whenever deciding on whether or not to have a fuel drain:

  1. How much Petrol did you put in to the Maserati, taking into consideration that the fuel capacity of your Maserati Ghibli Diesel is normally about 70 litres?
    1. A tiny quantity of Petrol, as little as 3.5 litres of Petrol in a Diesel Ghibli Diesel will in most cases not necessarily be a big problem. Experience has taught us that quantities under 3.5 litres (which is about 5% of the fuel tank volume) is usually able to be sufficiently diluted simply by completely topping up the tank with the correct fuel.
      It is pretty uncommon to find a motor vehicle having issues with under 5% wrong fuel contamination. Keep in mind that it's uncommon - not impossible to find. There are a few cars that won't stand any amount of contamination whatsoever.
    2. Somewhere between 3.5 and 7 litres of Petrol in the Maserati (5 to 10%) is a 50/50 scenario. Our expertise has demonstrated that as many drivers get away with it as those who don't. When deciding upon whether or not to risk it and basically top it up recognise that it is just like gambling it all on black - you've got a 50/50 chance of it working.
    3. Anything in excess of 7 litres of Petrol in your Diesel Ghibli Diesel should right away be drained since your probability of getting away with this amount of contamination is very likely lower than one in 50 - seriously huge odds.
  2. Put Petrol in a Diesel Maserati and drove it: Have you seen any performance concerns after putting the incorrect fuel in your Ghibli Diesel? If you have, get it removed no matter the amount of Petrol or the contamination ratio. Still driving a car that is starting to suffer the consequences of fuel contamination will probably only lead to more and more harm being caused to your fuel system components.
  3. Are you interested in peace of mind?
    Then simply just get it emptied. Regardless of the contamination ratio, there is always some extent of danger resulting from running a Diesel motor on Diesel contaminated with Petrol. Possible results of driving on the wrong fuel can include the motor refusing to start, running unevenly, decrease in power, wearing of the high-pressure pump, worn or blocked injectors, and so forth. These are some of the most common Petrol in Diesel symptoms, and should you observe any of them then stop and have it drained right now.

Petrol in Diesel FAQs

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.
