Renault Fuel Drain


Filling up with Petrol in a Diesel Renault is a regularly occurring mistake. And exactly what you have to do about it is determined by several different things. Assuming you want to know what to do about this then please read on.
Listed below are the most crucial variables to think about when deciding on whether or not to get a fuel drain:

  1. What amount of Petrol did you put in to the Renault, taking into account that the fuel tank capacity of the Renault Grand Scenic dCi is in most cases approximately 60 litres?
    1. Hardly any Petrol, something like 3 litres of Petrol in a Diesel Grand Scenic dCi will in most cases not really be a huge problem. Experience has shown us that anything under 3 litres (which is almost 5% of the total fuel tank) is often capable of being adequately diluted by totally topping the tank with Diesel.
      It's rather unusual to find a car going through problems with less than 5% incorrect fuel contamination. Be aware that it is rare - definitely not impossible to encounter. You will discover some automobiles that won't endure any amount of contamination in the slightest.
    2. Anywhere between 3 and 6 litres of Petrol in the Renault (from 5 to 10%) is a 50/50 condition. Our working experience has demonstrated that as many people get away with this as those who don't. Whenever deciding whether or not to chance it and simply top it up bear in mind that it is the same as wagering all of it on black - you will have a 50/50 chance of it being ok.
    3. Anything in excess of 6 litres of Petrol in a Diesel Grand Scenic dCi should really straightaway be removed since your probability of succeeding with this amount of contamination is in all likelihood lower than one in fifty - really huge odds.
  2. Put some Petrol in a Diesel Renault and drove it: Have you noticed any performance troubles since putting the bad fuel in your Grand Scenic dCi? If you have, have it emptied irrespective of the volume of Petrol or the contamination percentage. Proceeding to run running a vehicle that is already starting to suffer from the effects of fuel contamination will definitely be responsible for more and more harm affecting the fuel system components.
  3. Are you interested in reassurance?
    Then simply just get it removed. Regardless of contamination ratio, there is inevitably a certain level of risk connected with operating a Diesel vehicle on fuel contaminated with Petrol. Probable implications of driving on the wrong fuel normally include the engine refusing to start, running unevenly, lack of power, degradation of the high-pressure pump, worn or blocked injectors, and so forth. These are some of the most frequently seen Petrol in Diesel signs or symptoms, and in the event that you observe any of them then cease driving and get it removed right now.

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.
