Renault Fuel Drain


Filling Petrol in a Diesel Renault is a regularly occurring mistake to make. And exactly what you want to do about it is determined by several factors. Assuming you would like to know what you should do about it then keep reading.
These are the key factors to take into account when making a decision whether to have the car drained:

  1. What level of Petrol did you put in the Renault, bearing in mind that the fuel tank capacity of the Renault Grand Modus dCi is probably around 51 litres?
    1. A modest quantity of Petrol, less than 2.55 litres of Petrol in a Diesel Grand Modus dCi will more often than not not necessarily be a massive problem. Experience has proven to us that an amount under 2.55 litres (approximately 5% of the whole fuel tank volume) is very often capable of being completely diluted by means of thoroughly filling up the rest of the tank with the appropriate fuel.
      It's pretty uncommon to come across a motor vehicle having issues due to below 5% incorrect fuel contamination. Keep in mind that it is very infrequently found - in no way impossible to find. You can get certain motor vehicles that won't stand any level of contamination at all.
    2. Anywhere between 2.55 and 5.1 litres of Petrol in the Renault (from 5 to 10%) is a 50/50 scenario. Our practical experience has revealed that as many people get away with it as those people who don't. When figuring out whether or not to chance it and just simply fill it up remember that it is the same thing as betting all of it on black - you have got a 50/50 chance of it being ok.
    3. Anything more than 5.1 litres of Petrol in a Diesel Grand Modus dCi must straightaway be drained seeing that your likelihood of driving with this level of contamination is very likely lower than one in 50 - truly big odds.
  2. Put Petrol in a Diesel Renault and drove it: Have you spotted any performance difficulties since putting the incorrect fuel in your Grand Modus dCi? If you have, have it drained irrespective of the quantity of Petrol or the contamination percentage. Proceeding to run driving a motor vehicle that is currently beginning to suffer the effects of fuel contamination will only be responsible for progressively more damage affecting the fuel system.
  3. Are you interested in assurance?
    Then simply just get it emptied. No matter the contamination percentage, there is always some amount of danger affiliated with running a Diesel engine on fuel contaminated with Petrol. Possible consequences of driving a vehicle on the wrong fuel can include the engine not starting, running unevenly, loss of power, degradation of the high-pressure pump, worn or bunged injectors, and the like. These are several of the most frequently seen Petrol in Diesel symptoms, and should you detect any of them then cease driving and have it removed asap.

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.
