Renault Fuel Drain


Filling Diesel in a Petrol Renault is a common problem. And its remedy hinges on an assortment of things. In the event that you would like to know what you must do to fix it then stay with me.
These are the most crucial variables to be aware of whenever deciding whether to get your car drained:

  1. How much Diesel have you put in to the Renault, taking into account that the fuel tank capacity of the Renault Clio is normally roughly 45 litres?
    1. Hardly any Diesel, as little as 2.25 litres of Diesel in a Petrol Clio will in most situations not really be a huge problem. Experience has taught us that anything under 2.25 litres (which is roughly 5% of the entire fuel tank capacity) is usually capable of being completely diluted by thoroughly filling up the tank with the right fuel.
      It's highly rare to come across a car or truck experiencing issues due to lower than 5% wrong fuel contamination. Remember that it is very infrequent - certainly not impossible to find. You will discover certain automobiles that will not stand any level of contamination at all.
    2. Somewhere between 2.25 and 4.5 litres of Diesel in the Renault (from 5 to 10%) is more of a 50/50 situation. Our working experience has shown that as many motorists get away with this as those who don't. When you are deciding upon whether to risk it and just simply top it up recognise that it is the same as gambling all of it on black - you have got a 50/50 chance of it working.
    3. Anything above 4.5 litres of Diesel in your Petrol Clio must straight away be removed because your likelihood of driving with that quantity of contamination is more than likely below one in 50 - really long odds.
  2. Put some Diesel in a Petrol Renault and drove it: Have you detected any kind of performance concerns since putting the wrong fuel in your Clio? If so, have it emptied no matter the amount of Diesel or the contamination percentage. Continuing to drive running a car that is currently starting to suffer from the effects of fuel contamination can likely bring about even more harm affecting the fuel system parts.
  3. Are you interested in assurance?
    Then get it emptied. Regardless of contamination ratio, there is always some degree of danger associated with running a Petrol engine on Petrol contaminated with the incorrect fuel. Probable results of driving a vehicle on the incorrect fuel include the motor not starting, running unevenly, loss in power, wearing of the high-pressure pump, damaged or blocked injectors, and so forth. These are several of the most common Diesel in Petrol warning signs, and should you recognise any of them then stop and have it removed as soon as possible.

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.
