Renault Fuel Drain


Filling Petrol in a Diesel Renault is a usual error. And exactly what you need to do about it is based on an assortment of factors. In the event that you would like to find out what you have to do to fix it then keep on reading.
These are the most important factors to take into account when deciding whether or not to have the car drained:

  1. How much Petrol did you put into the Renault, taking into consideration that the fuel tank capacity of your Renault Modus dCi is normally approximately 49 litres?
    1. A small amount of Petrol, as little as 2.45 litres of Petrol in a Diesel Modus dCi will in most cases not necessarily be a major problem. Experience has shown us that anything under 2.45 litres (approximately 5% of the total fuel tank volume) is frequently able to be sufficiently diluted through entirely filling the remainder of the tank with Diesel.
      It is extremely rare to encounter a car suffering from issues with below 5% wrong fuel contamination. Keep in mind that it's infrequent - in no way impossible to encounter. You will discover a number of motor vehicles that will not endure any quantity of fuel contamination in the slightest.
    2. Anywhere between 2.45 and 4.9 litres of Petrol in the Renault (from 5 to 10%) is really a 50/50 condition. Our experience has demonstrated that as many drivers get away with this as those who break down. Whenever trying to decide whether to risk it and just fill it up consider that it is the same thing as wagering your car on black - you have got a 50/50 chance of it being ok.
    3. Anything in excess of 4.9 litres of Petrol in a Diesel Modus dCi ought to straightaway be drained out since your probability of driving with this level of contamination is probably lower than one in fifty - extremely long odds.
  2. Put some Petrol in a Diesel Renault and drove it: Have you observed any performance issues ever since putting the incorrect fuel in your Modus dCi? If so, get it emptied no matter the amount of Petrol or the contamination percentage. Still running a vehicle that is now starting to suffer from the consequences of fuel contamination will typically lead to increasing amounts of harm being done to the fuel system parts.
  3. Are you looking for reassurance?
    In that case get it emptied. Regardless of the contamination ratio, there is always some degree of risk associated with running a Diesel engine on Diesel contaminated with Petrol. Probable final outcomes of driving a vehicle on the incorrect fuel include the motor not starting, running unevenly, decrease in power, degradation of the high-pressure pump, damaged or bunged injectors, and the like. These are several of the most common Petrol in Diesel signs or symptoms, and in the event that you recognise any of them then stop and have it removed 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.
