Peugeot Fuel Drain


Putting Diesel in a Petrol Peugeot is a regular mistake. And its remedy depends on a variety of factors. Assuming you want to find out what it is best to do to fix it then read on.
These are the key variables to think about whenever deciding on whether to have your car drained:

  1. How much Diesel did you put into the Peugeot, bearing in mind that the fuel capacity of the Peugeot 308 CC is usually about 60 litres?
    1. Hardly any Diesel, something like 3 litres of Diesel in a Petrol 308 CC will in most situations not be a massive problem. Experience has proven to us that quantities less than 3 litres (roughly 5% of the entire fuel tank) is often capable of being adequately diluted by means of wholly topping up the rest of the tank with Petrol.
      It's quite rare to come across a motor vehicle having difficulties with lower than 5% wrong fuel contamination. Do not forget that it is very unusual - not impossible to find. You will discover certain vehicles that won't endure any level of contamination at all.
    2. Between 3 and 6 litres of Diesel in the Peugeot (5 to 10%) is really a 50/50 situation. Our experience has revealed that as many people get away with this as those who break down. Any time you are deciding upon whether or not to risk it and simply fill it up bear in mind that it is exactly like gambling your car on black - you've got a 50/50 chance of it being ok.
    3. Anything more than 6 litres of Diesel in your Petrol 308 CC should really immediately be drained out since your probability of succeeding with that level of contamination is almost certainly less than one in 50 - really big odds.
  2. Put Diesel in a Petrol Peugeot and drove it: Have you spotted any kind of performance problems after putting the wrong fuel in your 308 CC? If so, have it emptied irrespective of the quantity of Diesel or the contamination ratio. Continuing to run driving a vehicle that is already beginning to suffer from the consequences of fuel contamination will probably typically lead to more and more harm being caused to your fuel system.
  3. Are you interested in assurance?
    In that case get it emptied. No matter the contamination percentage, there is invariably some amount of risk associated with operating a Petrol engine on Petrol contaminated with Diesel. Probable final outcomes of driving on the wrong fuel can include the engine refusing to start, running unevenly, losing power, wearing of the high-pressure pump, damaged or bunged injectors, and the like. These are several of the most common Diesel in Petrol symptoms, and if you detect any of them cease driving and get it removed right now.

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.
