Renault Fuel Drain


Filling Diesel in a Petrol Renault is a usual problem. And its solution depends on a few factors. In the event that you would like to know what it is best to do about this then stay with me.
These are the key factors to consider whenever making a decision whether or not to have a fuel drain:

  1. What amount of Diesel did you put in to the Renault, keeping in mind that the fuel capacity of the Renault Grand Scenic is in most cases around 60 litres?
    1. A modest amount of Diesel, something like 3 litres of Diesel in a Petrol Grand Scenic will normally not really be a massive problem. Experience has proven to us that quantities under 3 litres (which is about 5% of the entire fuel tank capacity) is generally able to be sufficiently diluted through entirely topping the tank with the correct fuel.
      It's highly unusual to encounter a car going through difficulties due to under 5% wrong fuel contamination. Keep in mind it is very rare - definitely not impossible to find. There are certain motor vehicles that will not stand any amount of fuel contamination in the slightest.
    2. In between 3 and 6 litres of Diesel in the Renault (5 to 10%) is more of a 50/50 scenario. Our working experience has proven that as many motorists get away with it as those people who don't. When you are deciding upon whether or not to risk it and just simply top it up recognise that it is exactly like betting everything on black - you will have a 50/50 chance of it being ok.
    3. Anything in excess of 6 litres of Diesel in a Petrol Grand Scenic should right away be drained out seeing that your probability of driving with this amount of contamination is certainly lower than one in 50 - seriously big odds.
  2. Put Diesel in a Petrol Renault and drove it: Have you noticed any performance issues ever since putting the bad fuel in your Grand Scenic? In that case, get it emptied regardless of the volume of Diesel or even the contamination percentage. Continually running a vehicle that is currently starting to suffer the effects of fuel contamination will only result in more and more damage affecting your fuel system parts.
  3. Are you interested in security?
    You should get it removed. Regardless of contamination percentage, there is invariably some extent of danger associated with operating a Petrol vehicle on fuel contaminated with Diesel. Probable outcomes of driving on the wrong fuel include the engine refusing to start, running lumpy, losing power, wearing of the high-pressure pump, worn out or clogged injectors, etc. These are some of the most frequently seen Diesel in Petrol symptoms, and if you recognise any of them then stop driving and get it drained asap.

Diesel in Petrol Questions

When someone has put Diesel in a Petrol car they have a few very common questions. So we have compiled a list of the most Frequently Asked Questions for you

I put Diesel in a Petrol 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 Petrol car on Diesel 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 Diesel can I get away with in a Petrol 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 Petrol 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.
