Fiat Fuel Drain


Putting Diesel in a Petrol Fiat is a common mistake to make. And its remedy is dependent upon an assortment of factors. If you want to know what you should do about it then continue reading.
Here are the most important factors to to consider whenever determining whether or not to have your car drained:

  1. What level of Diesel did you put into the Fiat, taking into account that the fuel capacity of the Fiat Cinquecento is usually roughly 35 litres?
    1. A tiny quantity of Diesel, something like 1.75 litres of Diesel in a Petrol Cinquecento will in most cases not really be a significant problem. Experience has proven to us that an amount less than 1.75 litres (which is 5% of the overall fuel tank volume) is in many instances capable of being completely diluted by means of thoroughly filling up the remainder of the tank with Petrol.
      It's quite uncommon to find a car going through problems because of less than 5% incorrect fuel contamination. Keep in mind it is infrequent - not impossible to find. You will discover certain vehicles that don't stand any level of fuel contamination at all.
    2. Between 1.75 and 3.5 litres of Diesel in the Fiat (5 to 10%) is more of a 50/50 scenario. Our practical experience has confirmed that as many drivers get away with it as those people who break down. When deciding upon whether to chance it and basically fill it up recognise that it is exactly like wagering it all on black - you will have a 50/50 chance of it being ok.
    3. Anything above 3.5 litres of Diesel in your Petrol Cinquecento ought to immediately be drained because your likelihood of getting away with this level of contamination is undoubtedly lower than one in 50 - really huge odds.
  2. Put Diesel in a Petrol Fiat and drove it: Have you noticed any kind of performance concerns ever since putting the bad fuel in your Cinquecento? If so, get it emptied regardless of the volume of Diesel or the contamination percentage. Continually running a motor vehicle that is currently beginning to suffer the effects of wrong fuel contamination will probably just cause increasing amounts of harm affecting your fuel system.
  3. Would you like assurance?
    Then simply just get it emptied. Whatever the contamination ratio, there is invariably a certain level of danger affiliated with running a Petrol vehicle on Petrol contaminated with Diesel. Likely results of driving on the incorrect fuel include the motor not starting, running lumpy, decrease in power, degradation of the high-pressure pump, worn out or clogged injectors, and so forth. These are some of the commonest Diesel in Petrol symptoms, and if you recognise any of them 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.
