Dacia Fuel Drain


Putting Diesel in a Petrol Dacia is a regular problem. And what you need to do about it is determined by a number of things. In case you want to know what it is advisable to do to fix it then please read on.
Here are the main factors to consider whenever determining whether or not to have a fuel drain:

  1. Exactly how much Diesel did you put into the Dacia, taking into consideration that the fuel tank capacity of the Dacia Logan is most likely approximately 50 litres?
    1. Hardly any Diesel, less than 2.5 litres of Diesel in a Petrol Logan will normally not be a huge problem. Experience has taught us that an amount under 2.5 litres (roughly 5% of the fuel tank capacity) is usually able to be sufficiently diluted by wholly filling up the rest of the tank with the right fuel.
      It is relatively rare to find a motor vehicle having problems with lower than 5% wrong fuel contamination. Be aware that it's uncommon - definitely not impossible to encounter. There are certain vehicles that don't stand any quantity of contamination in the slightest.
    2. In between 2.5 and 5 litres of Diesel in the Dacia (5 to 10%) is more of a 50/50 situation. Our practical experience has shown us that as many people get away with this as those people who break down. Any time you are deciding on whether or not to risk it and simply fill it up consider that it is very much like betting everything on black - you have a 50/50 chance of it working.
    3. Anything in excess of 5 litres of Diesel in a Petrol Logan should straight away be drained as your likelihood of succeeding with this level of contamination is in all likelihood below one in 50 - really big odds.
  2. Put Diesel in a Petrol Dacia and drove it: Have you detected any kind of performance concerns as a result of putting the wrong fuel in the Logan? If you have, get it drained irrespective of the quantity of Diesel or the contamination percentage. Proceeding to run running a vehicle that is currently beginning to suffer the effects of fuel contamination can definitely end up in increasing amounts of damage being done to the fuel system parts.
  3. Would you like peace of mind?
    Simply get it emptied. Whatever the contamination ratio, there is always some degree of risk caused by running a Petrol vehicle on fuel contaminated with the incorrect fuel. Likely outcomes of driving on the incorrect fuel include the engine not starting, running unevenly, reduced power, degradation of the high-pressure pump, worn or blocked injectors, etc. These are a few of the most frequently seen Diesel in Petrol signs or symptoms, and if you recognise any of them stop and have it drained right now.

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.
