Fiat Fuel Drain


Filling up with Petrol in a Diesel Fiat is a very common mistake to make. And exactly what you have to do about it hinges on a few things. If perhaps you want to know what to do to fix it then stay with me.
Here are the most important factors to to consider whenever figuring out whether to have the car drained:

  1. How much Petrol have you put into the Fiat, considering that the fuel tank capacity of your Fiat Stilo Multijet is most likely around 58 litres?
    1. A modest quantity of Petrol, as little as 2.9 litres of Petrol in a Diesel Stilo Multijet will most of the time not really be a big problem. Experience has proven to us that anything under 2.9 litres (close to 5% of the total fuel tank volume) is very often capable of being sufficiently diluted by totally filling up the remainder of the tank with the appropriate fuel.
      It's pretty rare to come across a car experiencing issues due to below 5% incorrect fuel contamination. Keep in mind it is unusual - definitely not impossible to encounter. There are actually certain cars that will not endure any level of contamination in the slightest.
    2. Between 2.9 and 5.8 litres of Petrol in the Fiat (from 5 to 10%) is more of a 50/50 situation. Our expertise has demonstrated that as many people get away with this as those who don't. Whenever you are figuring out whether to risk it and just simply top it up remember that it is exactly like betting your car on black - you've got a 50/50 chance of it working out.
    3. Anything over 5.8 litres of Petrol in your Diesel Stilo Multijet should really straight away be removed as your likelihood of driving with that quantity of contamination is almost certainly less than one in fifty - extremely huge odds.
  2. Put Petrol in a Diesel Fiat and drove it: Have you noted any performance issues since putting the bad fuel in the Stilo Multijet? If you have, have it removed no matter the amount of Petrol or even the contamination percentage. Continuing to run running a car that is already beginning to suffer the effect of wrong fuel contamination can only end up in more harm affecting the fuel system.
  3. Are you looking for reassurance?
    Then simply just get it drained. Whatever the contamination ratio, there is inevitably some extent of risk linked with running a Diesel engine on Diesel contaminated with Petrol. Likely implications of driving on the wrong fuel include things like the engine refusing to start, running unevenly, lack of power, degradation of the high-pressure pump, worn out or blocked injectors, and so forth. These are some of the commonest Petrol in Diesel symptoms, and should you observe any of them stop and have it drained asap.

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.
