Renault Fuel Drain


Filling up with Petrol in a Diesel Renault is a well-known problem. And its remedy depends upon various things. If you would like to find out what you ought to do about this then continue reading.
Listed below are the most crucial factors to to consider when figuring out whether or not to get your car drained:

  1. What level of Petrol have you put in to the Renault, taking into account that the fuel capacity of your Renault Megane dCi is in most cases approximately 60 litres?
    1. Hardly any Petrol, as little as 3 litres of Petrol in a Diesel Megane dCi will usually not necessarily be a massive problem. Experience has demonstrated to us that quantities less than 3 litres (which is close to 5% of the total fuel tank capacity) is quite often able to be completely diluted simply by completely topping up the remainder of the tank with Diesel.
      It's pretty rare to encounter a vehicle suffering from problems with lower than 5% incorrect fuel contamination. Remember that it's infrequently found - in no way impossible to find. You can get a number of automobiles that don't endure any amount of contamination in the slightest.
    2. Anywhere between 3 and 6 litres of Petrol in the Renault (from 5 to 10%) is a 50/50 situation. Our working experience has demonstrated that as many motorists get away with it as those people who break down. Whenever deciding whether or not to chance it and just top it up consider that it is the same thing as betting everything on black - you will have a 50/50 possibility of it being ok.
    3. Anything above 6 litres of Petrol in your Diesel Megane dCi should promptly be drained out seeing that your probability of getting away with that amount of contamination is probably below one in 50 - extremely long odds.
  2. Put Petrol in a Diesel Renault and drove it: Have you detected any performance issues as a result of putting the wrong fuel in your Megane dCi? If so, get it emptied irrespective of the quantity of Petrol or even the contamination percentage. Continuing to drive running an automobile that is beginning to suffer the consequences of wrong fuel contamination can likely cause progressively more harm being done to your fuel system components.
  3. Are you looking for reassurance?
    Then simply just get it removed. Regardless of the contamination percentage, there is always some extent of threat connected with running a Diesel motor on fuel contaminated with the incorrect fuel. Probable implications of driving a car on the incorrect fuel can include the motor refusing to start, running unevenly, lack of power, degradation of the high-pressure pump, worn or bunged injectors, etc. These are several of the most frequently seen Petrol in Diesel signs and symptoms, and if you recognise any of them then stop and have it drained as soon as possible.

Petrol in Diesel Questions

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.
