Hyundai Fuel Drain


Putting Diesel in a Petrol Hyundai is a regular mistake to make. And its remedy depends on a number of things. If you would like to find out what you need to do to sort it out then keep on reading.
Listed here are the key variables to be aware of whenever figuring out whether to get a fuel drain:

  1. How much Diesel did you put in to the Hyundai, taking into consideration that the fuel tank capacity of your Hyundai i20 is in most cases approximately 45 litres?
    1. Hardly any Diesel, less than 2.25 litres of Diesel in a Petrol i20 will typically not really be a huge problem. Experience has taught us that anything under 2.25 litres (5% of the whole fuel tank volume) is often able to be adequately diluted by means of entirely filling the remainder of the tank with the appropriate fuel.
      It is pretty unusual to find a motor vehicle having problems due to under 5% wrong fuel contamination. Be aware that it is uncommon - not impossible to encounter. There are some automobiles that don't endure any degree of fuel contamination at all.
    2. Anywhere between 2.25 and 4.5 litres of Diesel in the Hyundai (5 to 10%) is really a 50/50 condition. Our experience has shown that as many drivers get away with it as all those who break down. Any time you are deciding on whether to risk it and just simply fill it up bear in mind that it is much like betting all of it on black - you have a 50/50 possibility of it working.
    3. Anything more than 4.5 litres of Diesel in your Petrol i20 should straight away be drained out seeing as your probability of succeeding with that quantity of contamination is more than likely less than one in 50 - really huge odds.
  2. Put some Diesel in a Petrol Hyundai and drove it: Have you observed any kind of performance concerns since putting the bad fuel in your i20? If that's the case, get it emptied no matter the volume of Diesel or even the contamination ratio. Continuing to drive running a motor vehicle that is now starting to suffer from the effect of wrong fuel contamination will probably definitely result in even more harm affecting the fuel system components.
  3. Are you looking for reassurance?
    Then get it removed. No matter the contamination ratio, there is always some extent of risk connected with driving a Petrol vehicle on fuel contaminated with the incorrect fuel. Likely outcomes of driving a car on the wrong fuel can include the motor refusing to start, running unevenly, decrease in power, wearing of the high-pressure pump, worn out or bunged injectors, and so forth. These are some of the most frequently seen Diesel in Petrol signs and symptoms, and in the event that you notice any of them then stop driving and get it drained right away.

Diesel in Petrol Questions

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.
