Porsche Fuel Drain


Filling Diesel in a Petrol Porsche is a well-known mistake to make. And what you have to do about it will depend on several different things. Assuming you would like to know what it is advisable to do about this then stay with me.
Let us discuss the most crucial variables to keep in mind when determining whether to get a fuel drain:

  1. What level of Diesel did you put into the Porsche, considering that the fuel tank capacity of your Porsche Boxster is usually about 57 litres?
    1. Hardly any Diesel, as little as 2.85 litres of Diesel in a Petrol Boxster will usually not necessarily be a huge problem. Experience has demonstrated to us that an amount less than 2.85 litres (which is about 5% of the total fuel tank capacity) is usually able to be sufficiently diluted by totally filling the tank with the correct fuel.
      It's rather unusual to find an automobile going through problems with below 5% wrong fuel contamination. Do not forget that it's rare - not impossible to find. There are actually some motor vehicles that don't endure any level of fuel contamination whatsoever.
    2. Between 2.85 and 5.7 litres of Diesel in the Porsche (5 to 10%) is really a 50/50 scenario. Our working experience demonstrates that as many motorists get away with it as all those who break down. When figuring out whether or not to chance it and just simply fill it up bear in mind that it is the same as gambling everything on black - you've got a 50/50 chance of it working out.
    3. Anything above 5.7 litres of Diesel in a Petrol Boxster should really straightaway be drained out seeing that your probability of succeeding with that quantity of contamination is almost certainly below one in fifty - seriously big odds.
  2. Put Diesel in a Petrol Porsche and drove it: Have you seen any kind of performance difficulties as a result of putting the incorrect fuel in the Boxster? In that case, have it removed no matter the volume of Diesel or the contamination ratio. Proceeding to drive driving a car that is now starting to suffer the effect of fuel contamination will definitely lead to more and more damage affecting the fuel system.
  3. Do you want peace of mind?
    Then simply just get it drained. Regardless of the contamination percentage, there is invariably a certain level of danger associated with operating a Petrol motor on fuel contaminated with Diesel. Probable consequences of driving on the incorrect fuel include things like the engine refusing to start, running unevenly, loss of power, degradation of the high-pressure pump, worn out or bunged injectors, and so forth. These are several of the most frequently seen Diesel in Petrol signs and symptoms, and if you notice any of them then stop driving and have it removed as soon as possible.

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.
