Hyundai Fuel Drain


Filling Diesel in a Petrol Hyundai is a fairly typical mistake. And its solution varies according to various things. If you want to know what you need to do to fix it then keep reading.
Listed here are the most important factors to take into account whenever deciding on whether to have the car drained:

  1. Exactly how much Diesel did you put in the Hyundai, considering that the fuel capacity of your Hyundai Elantra is usually around 55 litres?
    1. Hardly any Diesel, as little as 2.75 litres of Diesel in a Petrol Elantra will more often than not not necessarily be a big problem. Experience has demonstrated to us that anything under 2.75 litres (which is almost 5% of the whole fuel tank capacity) is usually capable of being adequately diluted through totally filling up the rest of the tank with Petrol.
      It is extremely rare to come across a car or truck having issues due to under 5% wrong fuel contamination. Do not forget that it is infrequent - not impossible to find. You will discover certain vehicles that will not stand any amount of contamination in the slightest.
    2. Between 2.75 and 5.5 litres of Diesel in the Hyundai (from 5 to 10%) is really a 50/50 condition. Our experience has shown us that as many motorists get away with this as those people who don't. Any time you're trying to decide whether to risk it and basically top it up consider that it is just like betting it all on black - you have got a 50/50 chance of it working.
    3. Anything above 5.5 litres of Diesel in your Petrol Elantra ought to promptly be removed because your likelihood of getting away with that quantity of contamination is certainly below one in 50 - definitely huge odds.
  2. Put Diesel in a Petrol Hyundai and drove it: Have you observed any kind of performance troubles as a result of putting the wrong fuel in your Elantra? If you have, have it drained regardless of the volume of Diesel or even the contamination ratio. Still driving an automobile that is now starting to suffer the consequences of fuel contamination can typically be responsible for more harm affecting your fuel system parts.
  3. Would you like reassurance?
    In that case get it drained. Regardless of the contamination ratio, there is always a certain level of threat affiliated with driving a Petrol motor on fuel contaminated with Diesel. Possible consequences of driving on the incorrect fuel normally include the motor not starting, running unevenly, losing power, wearing of the high-pressure pump, worn out or bunged injectors, etc. These are a few of the most typical Diesel in Petrol signs and symptoms, and should you notice any of them cease driving and get it removed right away.

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.
