Renault Fuel Drain


Filling Diesel in a Petrol Renault is a well-known problem. And what you need to do about it is determined by several things. In the event that you would like to find out what it is best to do to fix it then read on.
Listed here the most important factors to take into account when figuring out whether or not to get your car drained:

  1. What level of Diesel did you put into the Renault, taking into account that the fuel capacity of the Renault Sport Spider is usually around 50 litres?
    1. A modest quantity of Diesel, something like 2.5 litres of Diesel in a Petrol Sport Spider will more often than not not necessarily be a huge problem. Experience has shown us that quantities less than 2.5 litres (which is about 5% of the overall fuel tank) is oftentimes capable of being adequately diluted by thoroughly topping up the remainder of the tank with the appropriate fuel.
      It is rather uncommon to come across a car or truck experiencing issues with less than 5% incorrect fuel contamination. Remember that it is infrequent - not impossible to find. You can get a few cars that will not stand any level of fuel contamination whatsoever.
    2. Between 2.5 and 5 litres of Diesel in the Renault (5 to 10%) is a 50/50 situation. Our working experience demonstrates that as many motorists get away with this as those who break down. When deciding whether or not to risk it and just simply top it up bear in mind that it is exactly like wagering your car on black - you have a 50/50 possibility of it working out.
    3. Anything over 5 litres of Diesel in a Petrol Sport Spider ought to immediately be drained as your probability of driving with that level of contamination is very likely less than one in 50 - seriously long odds.
  2. Put some Diesel in a Petrol Renault and drove it: Have you noticed any performance difficulties since putting the wrong fuel in your Sport Spider? If so, get it emptied no matter the volume of Diesel or even the contamination percentage. Continually running a car that is now beginning to suffer from the effect of fuel contamination will probably definitely be responsible for more and more harm affecting the fuel system components.
  3. Would you like reassurance?
    In that case get it emptied. Whatever the contamination ratio, there is inevitably some amount of threat affiliated with driving a Petrol engine on fuel contaminated with the wrong fuel. Possible outcomes of driving a car on the wrong fuel include things like the engine not starting, running unevenly, loss of power, wearing of the high-pressure pump, worn out or clogged injectors, etc. These are several of the most frequently seen Diesel in Petrol signs and symptoms, and should you observe any of them stop and get it drained asap.

Diesel in Petrol FAQs

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.
