Renault Fuel Drain


Filling up with Petrol in a Diesel Renault is a regularly occurring error. And what you need to do about it hinges on several different things. In the event that you would like to know what you need to do to fix it then stay with me.
Listed here the most crucial factors to to consider whenever choosing whether to get the car drained:

  1. Exactly how much Petrol did you put into the Renault, keeping in mind that the fuel tank capacity of your Renault Laguna dCi is most likely around 66 litres?
    1. A small amount of Petrol, something like 3.3 litres of Petrol in a Diesel Laguna dCi will more often than not not be a massive problem. Experience has proven to us that an amount less than 3.3 litres (roughly 5% of the total fuel tank) is sometimes able to be sufficiently diluted through totally filling up the remainder of the tank with Diesel.
      It's extremely rare to come across a car or truck having problems because of under 5% wrong fuel contamination. Remember that it is rare - definitely not impossible to encounter. You can get a few cars that don't stand any quantity of contamination in the slightest.
    2. Somewhere between 3.3 and 6.6 litres of Petrol in the Renault (from 5 to 10%) is a 50/50 situation. Our working experience has shown that as many motorists get away with it as those people who break down. Any time you're deciding on whether or not to risk it and just top it up recognise that it is the same thing as betting everything on black - you have got a 50/50 chance of it working out.
    3. Anything more than 6.6 litres of Petrol in your Diesel Laguna dCi ought to immediately be removed as your likelihood of getting away with this amount of contamination is undoubtedly below one in 50 - definitely long odds.
  2. Put some Petrol in a Diesel Renault and drove it: Have you seen any performance concerns ever since putting the bad fuel in your Laguna dCi? If that's the case, have it emptied no matter the quantity of Petrol or the contamination ratio. Still running an automobile that is now beginning to suffer the effects of wrong fuel contamination can likely lead to more and more damage affecting your fuel system parts.
  3. Would you like assurance?
    Then simply just get it drained. Whatever the contamination ratio, there is invariably some extent of threat affiliated with running a Diesel motor on Diesel contaminated with Petrol. Likely results of driving on the incorrect fuel can include the engine not starting, running unevenly, lack of power, degradation of the high-pressure pump, damaged or clogged injectors, and so forth. These are some of the most common Petrol in Diesel signs or symptoms, and should you notice any of them stop driving and have it drained right now.

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.
