Porsche Fuel Drain


Filling Petrol in a Diesel Porsche is a usual problem. And what you should do about it hinges on various things. Assuming you would like to know what to do about it then stay with me.
Listed here the main factors to keep in mind whenever making a decision whether to have it drained:

  1. What amount of Petrol have you put in to the Porsche, taking into consideration that the fuel capacity of the Porsche Cayenne Diesel is in most cases about 100 litres?
    1. Hardly any Petrol, less than 5 litres of Petrol in a Diesel Cayenne Diesel will typically not be a big problem. Experience has shown us that anything under 5 litres (which is approximately 5% of the whole fuel tank) is generally capable of being completely diluted simply by totally filling the remainder of the tank with the correct fuel.
      It is very rare to encounter a car suffering from difficulties with below 5% wrong fuel contamination. Bear in mind that it's rare - certainly not impossible to find. There are some automobiles that don't stand any quantity of contamination in the slightest.
    2. Anywhere between 5 and 10 litres of Petrol in the Porsche (from 5 to 10%) is more of a 50/50 situation. Our expertise has shown that as many drivers get away with it as those who don't. When you are deciding upon whether or not to risk it and basically top it up bear in mind that it is just like betting all of it on black - you will have a 50/50 chance of it working out.
    3. Anything over 10 litres of Petrol in your Diesel Cayenne Diesel really should right away be drained since your probability of succeeding with that quantity of contamination is almost certainly less than one in 50 - genuinely huge odds.
  2. Put Petrol in a Diesel Porsche and drove it: Have you noted any kind of performance difficulties as a result of putting the bad fuel in your Cayenne Diesel? In that case, have it emptied irrespective of the volume of Petrol or even the contamination percentage. Still driving a motor vehicle that is starting to suffer the effect of wrong fuel contamination can likely lead to progressively more damage affecting your fuel system components.
  3. Are you looking for reassurance?
    You should get it removed. Regardless of contamination ratio, there is always some amount of threat affiliated with operating a Diesel engine on Diesel contaminated with the wrong fuel. Probable outcomes of driving a car on the wrong fuel include things like the motor refusing to start, running unevenly, decrease in power, degradation of the high-pressure pump, damaged or clogged injectors, and so on. These are a few of the most common Petrol in Diesel signs and symptoms, and in the event that you detect any of them then cease driving and get 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.
