Fiat Fuel Drain


Filling up with Petrol in a Diesel Fiat is a common mistake. And its remedy is determined by a variety of things. If you would like to find out what it is advisable to do about this then continue reading.
Listed here are the main variables to keep in mind when making a decision whether or not to get a fuel drain:

  1. What level of Petrol have you put in the Fiat, taking into consideration that the fuel capacity of your Fiat 500 Multijet is usually about 35 litres?
    1. A tiny amount of Petrol, less than 1.75 litres of Petrol in a Diesel 500 Multijet will typically not really be a major problem. Experience has proven to us that quantities less than 1.75 litres (roughly 5% of the whole fuel tank capacity) is in many instances capable of being sufficiently diluted by entirely topping the remainder of the tank with Diesel.
      It is rather uncommon to come across a car or truck having issues with under 5% incorrect fuel contamination. Keep in mind that it's uncommon - in no way impossible to find. There are certain cars that will not stand any level of fuel contamination whatsoever.
    2. In between 1.75 and 3.5 litres of Petrol in the Fiat (5 to 10%) is more of a 50/50 situation. Our experience has shown us that as many drivers get away with it as those who break down. Any time you're figuring out whether or not to chance it and basically top it up bear in mind that it is much like wagering your car on black - you will have a 50/50 possibility of it working out.
    3. Anything above 3.5 litres of Petrol in a Diesel 500 Multijet ought to as soon as possible be drained out because your probability of driving with that quantity of contamination is more than likely lower than one in 50 - extremely long odds.
  2. Put Petrol in a Diesel Fiat and drove it: Have you observed any kind of performance problems as a result of putting the incorrect fuel in the 500 Multijet? If so, have it drained no matter the volume of Petrol or the contamination percentage. Continuing to drive running an automobile that is currently starting to suffer the effects of fuel contamination will only bring about more damage affecting your fuel system components.
  3. Do you want peace of mind?
    In that case get it emptied. Whatever the contamination ratio, there is always a certain level of risk associated with operating a Diesel vehicle on Diesel contaminated with Petrol. Probable consequences of driving a vehicle on the wrong fuel include things like the motor not starting, running lumpy, decrease in power, wearing of the high-pressure pump, worn or clogged injectors, etc. These are a few of the most common Petrol in Diesel signs or symptoms, and in the event that you observe any of them cease driving and have it removed 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.
