Fiat Fuel Drain


Filling up with Diesel in a Petrol Fiat is a common mistake. And its remedy is dependent upon a variety of things. In the event that you want to find out what you should do about this then keep on reading.
These are the most crucial factors to keep in mind whenever making a decision whether to get the car drained:

  1. How much Diesel did you put into the Fiat, considering that the fuel tank capacity of your Fiat 500L is usually roughly 35 litres?
    1. A small quantity of Diesel, as little as 1.75 litres of Diesel in a Petrol 500L will usually not necessarily be a huge problem. Experience has proven to us that an amount less than 1.75 litres (almost 5% of the fuel tank volume) is sometimes able to be adequately diluted by means of completely filling the remainder of the tank with Petrol.
      It's quite uncommon to find an automobile going through difficulties with less than 5% incorrect fuel contamination. Keep in mind that it is infrequently found - not impossible to encounter. You will discover a number of cars that don't stand any quantity of contamination whatsoever.
    2. In between 1.75 and 3.5 litres of Diesel in the Fiat (5 to 10%) is really a 50/50 scenario. Our expertise has demonstrated that as many people get away with this as all those who break down. Any time you are deciding on whether or not to chance it and just simply fill it up recognise that it is the same as betting your car on black - you've got a 50/50 possibility of it being ok.
    3. Anything above 3.5 litres of Diesel in your Petrol 500L should really as soon as possible be drained out seeing as your likelihood of getting away with this amount of contamination is almost certainly less than one in fifty - extremely long odds.
  2. Put Diesel in a Petrol Fiat and drove it: Have you noted any performance problems since putting the bad fuel in your 500L? If so, have it removed no matter the amount of Diesel or the contamination ratio. Still running an automobile that is currently beginning to suffer from the effect of fuel contamination will only lead to even more damage affecting your fuel system.
  3. Are you looking for security?
    In that case get it drained. No matter the contamination ratio, there is inevitably some degree of danger linked with driving a Petrol motor on Petrol contaminated with the incorrect fuel. Probable final outcomes of driving a car on the wrong fuel can include the motor refusing to start, running lumpy, loss of power, degradation of the high-pressure pump, worn out or clogged injectors, and so forth. These are a few of the commonest Diesel in Petrol warning signs, and in the event that you recognise any of them then stop and have it removed 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.
