Renault Fuel Drain


Filling up with Petrol in a Diesel Renault is a regularly occurring mistake. And exactly what you need to do about it varies according to several different factors. In case you would like to find out what to do about it then continue reading.
Here are the main factors to think about when making a decision whether or not to have a fuel drain:

  1. What level of Petrol have you put in the Renault, keeping in mind that the fuel tank capacity of your Renault Avantime dCi is normally around 80 litres?
    1. A modest amount of Petrol, as little as 4 litres of Petrol in a Diesel Avantime dCi will normally not be a huge problem. Experience has shown us that anything under 4 litres (about 5% of the total fuel tank volume) is quite often capable of being completely diluted simply by totally filling the rest of the tank with Diesel.
      It's pretty uncommon to come across a car going through problems because of under 5% incorrect fuel contamination. Keep in mind that it's infrequent - certainly not impossible to find. You will discover certain automobiles that will not endure any level of fuel contamination at all.
    2. In between 4 and 8 litres of Petrol in the Renault (from 5 to 10%) is more of a 50/50 scenario. Our expertise has shown that as many motorists get away with this as all those who break down. Any time you are trying to decide whether or not to chance it and just fill it up consider that it is just like wagering all of it on black - you have a 50/50 chance of it working out.
    3. Anything over 8 litres of Petrol in a Diesel Avantime dCi should really as soon as possible be drained out because your likelihood of getting away with this amount of contamination is almost certainly lower than one in 50 - definitely big odds.
  2. Put some Petrol in a Diesel Renault and drove it: Have you seen any kind of performance difficulties after putting the bad fuel in the Avantime dCi? In that case, have it removed regardless of the quantity of Petrol or even the contamination percentage. Continuing to run running an automobile that is currently starting to suffer from the consequences of fuel contamination will definitely lead to more damage affecting the fuel system components.
  3. Are you looking for peace of mind?
    You should get it emptied. Whatever the contamination percentage, there is invariably some extent of threat associated with driving a Diesel engine on fuel contaminated with the incorrect fuel. Probable final outcomes of driving on the wrong fuel can include the engine refusing to start, running lumpy, losing power, wearing of the high-pressure pump, damaged or blocked injectors, and so forth. These are a few of the most common Petrol in Diesel signs and symptoms, and if you notice any of them stop and get it drained immediately.

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.
