Dacia Fuel Drain


Filling Petrol in a Diesel Dacia is a usual mistake to make. And its solution depends on several factors. If you want to find out what it is best to do to sort it out then stay with me.
Listed here the most crucial variables to consider when making a decision whether to have your car drained:

  1. Exactly how much Petrol have you put into the Dacia, taking into account that the fuel tank capacity of your Dacia Logan dCi is in most cases around 50 litres?
    1. A tiny amount of Petrol, less than 2.5 litres of Petrol in a Diesel Logan dCi will usually not really be a significant problem. Experience has shown us that an amount under 2.5 litres (roughly 5% of the whole fuel tank capacity) is in many instances able to be adequately diluted through totally filling up the remainder of the tank with the correct fuel.
      It's extremely rare to find a car or truck having issues with below 5% incorrect fuel contamination. Please remember it's uncommon - not impossible to find. There are actually a few vehicles that will not endure any degree of fuel contamination in the slightest.
    2. Between 2.5 and 5 litres of Petrol in the Dacia (5 to 10%) is really a 50/50 scenario. Our experience has proven that as many drivers get away with this as all those who don't. Whenever you are trying to decide whether to risk it and just simply fill it up bear in mind that it is just like gambling everything on black - you have got a 50/50 possibility of it working.
    3. Anything above 5 litres of Petrol in a Diesel Logan dCi must as soon as possible be removed because your probability of succeeding with that amount of contamination is probably lower than one in fifty - truly long odds.
  2. Put Petrol in a Diesel Dacia and drove it: Have you detected any kind of performance problems ever since putting the wrong fuel in your Logan dCi? If so, get it emptied irrespective of the amount of Petrol or the contamination ratio. Continually driving a vehicle that is already beginning to suffer the effect of wrong fuel contamination will probably just result in more and more damage affecting your fuel system.
  3. Do you want peace of mind?
    Then get it emptied. Regardless of contamination percentage, there is inevitably a certain level of danger resulting from driving a Diesel vehicle on fuel contaminated with Petrol. Possible consequences of driving a vehicle on the wrong fuel include things like the motor refusing to start, running lumpy, losing power, wearing of the high-pressure pump, damaged or clogged injectors, and so on. These are a few of the most common Petrol in Diesel signs or symptoms, and should you recognise any of them stop driving and get it removed right away.

Petrol in Diesel Questions

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.
