Fiat Fuel Drain


Filling up with Diesel in a Petrol Fiat is a common error. And its remedy will depend on various factors. In the event that you want to know what it is advisable to do to sort it out then keep on reading.
Let us discuss the most crucial variables to consider whenever deciding on whether to have the car drained:

  1. What amount of Diesel have you put in the Fiat, taking into account that the fuel capacity of your Fiat Doblo is normally roughly 60 litres?
    1. A small quantity of Diesel, as little as 3 litres of Diesel in a Petrol Doblo will more often than not not be a big problem. Experience has shown us that quantities less than 3 litres (which is 5% of the whole fuel tank volume) is oftentimes able to be sufficiently diluted through entirely filling up the remainder of the tank with Petrol.
      It's highly uncommon to come across a vehicle suffering from problems due to under 5% wrong fuel contamination. Keep in mind it's infrequent - in no way impossible to find. There are some automobiles that will not endure any quantity of fuel contamination at all.
    2. In between 3 and 6 litres of Diesel in the Fiat (5 to 10%) is really a 50/50 scenario. Our expertise has proven that as many motorists get away with it as those who break down. Any time you're deciding upon whether to chance it and basically fill it up recognise that it is just like betting all of it on black - you will have a 50/50 possibility of it being ok.
    3. Anything more than 6 litres of Diesel in your Petrol Doblo ought to straight away be drained as your likelihood of getting away with this level of contamination is certainly lower than one in fifty - seriously huge odds.
  2. Put some Diesel in a Petrol Fiat and drove it: Have you detected any performance problems after putting the bad fuel in your Doblo? If so, get it emptied no matter the amount of Diesel or even the contamination percentage. Continuing to drive driving a vehicle that is already beginning to suffer the effects of wrong fuel contamination can typically result in increasing amounts of damage being done to your fuel system components.
  3. Do you want security?
    In that case get it removed. Regardless of the contamination percentage, there is inevitably some degree of risk linked with driving a Petrol engine on Petrol contaminated with the wrong fuel. Probable final outcomes of driving on the wrong fuel include the engine not starting, running unevenly, decrease in power, degradation of the high-pressure pump, worn out or blocked injectors, and so on. These are several of the most frequently seen Diesel in Petrol signs or symptoms, and in the event that you detect any of them then stop driving and have it removed 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.
