Fiat Fuel Drain


Filling Diesel in a Petrol Fiat is a regular error. And what you should do about it varies according to a number of factors. In the event that you would like to find out what you ought to do to sort it out then keep reading.
Here are the key factors to keep in mind whenever making a decision whether to have your car drained:

  1. How much Diesel have you put in to the Fiat, considering that the fuel capacity of your Fiat Seicento is normally around 35 litres?
    1. A modest quantity of Diesel, less than 1.75 litres of Diesel in a Petrol Seicento will normally not necessarily be a major problem. Experience has proven to us that quantities less than 1.75 litres (which is almost 5% of the entire fuel tank volume) is frequently capable of being sufficiently diluted simply by entirely topping up the tank with Petrol.
      It is very unusual to encounter a car experiencing problems due to below 5% wrong fuel contamination. Keep in mind that it is very infrequent - not impossible to encounter. You will discover some motor vehicles that won't endure any amount of contamination in the slightest.
    2. Anywhere between 1.75 and 3.5 litres of Diesel in the Fiat (5 to 10%) is really a 50/50 condition. Our experience demonstrates that as many people get away with this as those people who break down. When trying to decide whether or not to chance it and simply top it up bear in mind that it is very much like wagering everything on black - you have a 50/50 possibility of it working out.
    3. Anything above 3.5 litres of Diesel in a Petrol Seicento must right away be drained seeing that your likelihood of driving with this level of contamination is almost certainly lower than one in fifty - definitely big odds.
  2. Put Diesel in a Petrol Fiat and drove it: Have you spotted any performance troubles ever since putting the incorrect fuel in your Seicento? If that's the case, have it drained regardless of the amount of Diesel or even the contamination percentage. Proceeding to run running a motor vehicle that is already beginning to suffer from the effects of wrong fuel contamination can definitely end up in even more damage affecting your fuel system.
  3. Do you want reassurance?
    Simply get it drained. Regardless of the contamination ratio, there is inevitably a certain level of risk caused by driving a Petrol engine on fuel contaminated with Diesel. Probable final outcomes of driving a car on the wrong fuel can include the engine not starting, running unevenly, losing power, wearing of the high-pressure pump, worn out or bunged injectors, etc. These are several of the most common Diesel in Petrol signs or symptoms, and in the event that you observe any of them stop and get it drained as soon as possible.

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.
