Fiat Fuel Drain


Putting Petrol in a Diesel Fiat is a regular mistake to make. And exactly what you need to do about it will depend on an assortment of factors. Assuming you want to know what you ought to do to fix it then keep reading.
Right here are the most crucial factors to think about whenever choosing whether to have a fuel drain:

  1. What amount of Petrol have you put in the Fiat, bearing in mind that the fuel tank capacity of your Fiat Marea JTD is usually approximately 63 litres?
    1. Hardly any Petrol, less than 3.15 litres of Petrol in a Diesel Marea JTD will generally not necessarily be a massive problem. Experience has shown us that anything less than 3.15 litres (close to 5% of the fuel tank volume) is in many instances able to be completely diluted simply by wholly filling up the tank with Diesel.
      It's pretty unusual to find a car going through difficulties due to below 5% wrong fuel contamination. Remember that it's infrequently found - definitely not impossible to find. There are actually some motor vehicles that don't endure any degree of contamination at all.
    2. Somewhere between 3.15 and 6.3 litres of Petrol in the Fiat (5 to 10%) is more of a 50/50 scenario. Our expertise has shown that as many motorists get away with this as all those who break down. Any time you are deciding whether or not to chance it and simply top it up remember that it is just like betting your car on black - you have a 50/50 possibility of it being ok.
    3. Anything in excess of 6.3 litres of Petrol in a Diesel Marea JTD should straight away be removed seeing that your likelihood of succeeding with that quantity of contamination is certainly below one in 50 - extremely long odds.
  2. Put some Petrol in a Diesel Fiat and drove it: Have you noticed any kind of performance difficulties since putting the wrong fuel in your Marea JTD? If you have, have it removed regardless of the volume of Petrol or the contamination percentage. Continuing to run driving a motor vehicle that is currently starting to suffer from the effect of wrong fuel contamination will probably just result in more and more harm being caused to the fuel system parts.
  3. Do you want reassurance?
    Then simply just get it removed. Whatever the contamination percentage, there is invariably some extent of risk in connection with operating a Diesel motor on fuel contaminated with Petrol. Probable outcomes of driving a vehicle on the wrong fuel include the motor refusing to start, running unevenly, reduced power, degradation of the high-pressure pump, damaged or blocked injectors, and the like. These are a few of the most frequently seen Petrol in Diesel symptoms, and in the event that you notice any of them stop driving and have it removed immediately.

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.
