Porsche Fuel Drain


Filling Diesel in a Petrol Porsche is a fairly typical mistake to make. And its remedy is dependent upon various factors. In the event that you want to know what you must do about this then read on.
Right here are the key factors to to consider when choosing whether to get your car drained:

  1. What amount of Diesel have you put in the Porsche, taking into account that the fuel capacity of the Porsche Cayenne is in most cases approximately 100 litres?
    1. A tiny amount of Diesel, as little as 5 litres of Diesel in a Petrol Cayenne will in most situations not be a major problem. Experience has taught us that quantities under 5 litres (which is approximately 5% of the whole fuel tank capacity) is in many instances capable of being completely diluted by totally topping up the tank with Petrol.
      It's highly rare to encounter a car suffering from difficulties due to less than 5% incorrect fuel contamination. Keep in mind it is very unusual - certainly not impossible to find. You will discover certain automobiles that will not endure any quantity of contamination whatsoever.
    2. Anywhere between 5 and 10 litres of Diesel in the Porsche (from 5 to 10%) is a 50/50 condition. Our working experience demonstrates that as many people get away with it as all those who don't. Whenever figuring out whether or not to risk it and basically fill it up recognise that it is the same as wagering everything on black - you have got a 50/50 chance of it working out.
    3. Anything above 10 litres of Diesel in your Petrol Cayenne should straightaway be drained seeing as your likelihood of driving with that quantity of contamination is undoubtedly less than one in 50 - definitely long odds.
  2. Put Diesel in a Petrol Porsche and drove it: Have you detected any performance problems ever since putting the incorrect fuel in the Cayenne? If that's the case, have it drained irrespective of the amount of Diesel or the contamination percentage. Proceeding to drive driving a motor vehicle that is starting to suffer from the effect of fuel contamination will just be responsible for even more damage affecting the fuel system parts.
  3. Do you want assurance?
    Simply get it emptied. Whatever the contamination ratio, there is always some extent of risk linked with operating a Petrol vehicle on Petrol contaminated with Diesel. Possible outcomes of driving on the incorrect fuel normally include the motor not starting, running lumpy, losing power, wearing of the high-pressure pump, damaged or bunged injectors, etc. These are some of the most common Diesel in Petrol signs or symptoms, and should you recognise any of them stop driving and get 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.
