Fiat Fuel Drain


Filling up with Diesel in a Petrol Fiat is a well-known problem. And exactly what you want to do about it depends upon a few factors. In case you want to know what you must do about this then keep on reading.
Here are the most crucial factors to consider when determining whether to get a fuel drain:

  1. How much Diesel did you put into the Fiat, bearing in mind that the fuel tank capacity of your Fiat A1 is most likely around 47 litres?
    1. A modest quantity of Diesel, as little as 2.35 litres of Diesel in a Petrol A1 will in most cases not necessarily be a big problem. Experience has proven to us that an amount under 2.35 litres (5% of the fuel tank capacity) is in many instances capable of being sufficiently diluted simply by wholly topping up the rest of the tank with the correct fuel.
      It is very uncommon to encounter a vehicle experiencing issues due to below 5% wrong fuel contamination. Remember that it's rare - definitely not impossible to encounter. There are certain cars that won't endure any level of fuel contamination in the slightest.
    2. Anywhere between 2.35 and 4.7 litres of Diesel in the Fiat (5 to 10%) is really a 50/50 scenario. Our expertise has shown that as many drivers get away with it as those people who don't. Whenever deciding whether to risk it and just simply fill it up remember that it is just like gambling all of it on black - you will have a 50/50 possibility of it being ok.
    3. Anything more than 4.7 litres of Diesel in your Petrol A1 really should straight away be drained out seeing as your probability of getting away with this level of contamination is certainly lower than one in fifty - seriously long odds.
  2. Put some Diesel in a Petrol Fiat and drove it: Have you spotted any kind of performance concerns since putting the incorrect fuel in the A1? In that case, have it emptied irrespective of the quantity of Diesel or even the contamination percentage. Continually running a vehicle that is currently beginning to suffer from the effects of fuel contamination will probably definitely bring about more and more damage affecting the fuel system parts.
  3. Are you interested in assurance?
    Then get it removed. No matter the contamination ratio, there is invariably some extent of danger resulting from running a Petrol engine on Petrol contaminated with the wrong fuel. Possible consequences of driving on the incorrect fuel can include the engine not starting, running lumpy, lack of power, wearing of the high-pressure pump, worn out or blocked injectors, and the like. These are several of the most frequently seen Diesel in Petrol symptoms, and if you observe any of them then stop and get it removed right away.

Diesel in Petrol FAQs

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.
