Hyundai Fuel Drain


Putting Petrol in a Diesel Hyundai is a regularly occurring error. And what you have to do about it depends upon various things. Assuming you would like to know what it is advisable to do about it then continue reading.
These are the most crucial factors to consider when deciding whether or not to have a fuel drain:

  1. How much Petrol did you put into the Hyundai, keeping in mind that the fuel capacity of your Hyundai Terracan CRDi is most likely around 75 litres?
    1. Hardly any Petrol, something like 3.75 litres of Petrol in a Diesel Terracan CRDi will in most situations not be a major problem. Experience has taught us that quantities under 3.75 litres (which is about 5% of the overall fuel tank volume) is sometimes able to be adequately diluted by completely filling up the tank with Diesel.
      It is rather unusual to find a car experiencing problems with below 5% wrong fuel contamination. Keep in mind that it's rare - not impossible to encounter. There are actually a number of automobiles that don't stand any quantity of fuel contamination whatsoever.
    2. Between 3.75 and 7.5 litres of Petrol in the Hyundai (from 5 to 10%) is really a 50/50 situation. Our working experience has confirmed that as many motorists get away with it as those people who don't. Any time you're deciding whether to risk it and basically fill it up recognise that it is the same thing as gambling all of it on black - you will have a 50/50 possibility of it working.
    3. Anything over 7.5 litres of Petrol in a Diesel Terracan CRDi ought to immediately be drained seeing that your likelihood of getting away with this quantity of contamination is very likely lower than one in fifty - truly huge odds.
  2. Put Petrol in a Diesel Hyundai and drove it: Have you noticed any performance issues as a result of putting the wrong fuel in the Terracan CRDi? If that's the case, get it drained no matter the quantity of Petrol or the contamination percentage. Continuing to drive running a vehicle that is currently beginning to suffer the effect of wrong fuel contamination can typically end up in more and more damage being done to your fuel system.
  3. Would you like security?
    Then get it drained. Regardless of the contamination percentage, there is invariably a certain level of risk resulting from operating a Diesel vehicle on fuel contaminated with Petrol. Possible outcomes of driving on the wrong fuel normally include the engine not starting, running lumpy, reduced power, degradation of the high-pressure pump, damaged or bunged injectors, and the like. These are a few of the most common Petrol in Diesel signs or symptoms, and in the event that you recognise any of them stop driving and have it removed right away.

Petrol in Diesel FAQs

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.
