Hyundai Fuel Drain


Filling Diesel in a Petrol Hyundai is a regular problem. And its remedy is dependent upon a few factors. In the event that you would like to find out what you have to do to fix it then continue reading.
Listed here are the most crucial variables to keep in mind whenever choosing whether or not to have the car drained:

  1. Exactly how much Diesel have you put into the Hyundai, considering that the fuel tank capacity of the Hyundai Tucson is normally around 58 litres?
    1. A modest amount of Diesel, something like 2.9 litres of Diesel in a Petrol Tucson will normally not be a big problem. Experience has proven to us that an amount less than 2.9 litres (almost 5% of the entire fuel tank) is quite often able to be adequately diluted by completely topping the remainder of the tank with Petrol.
      It is very uncommon to encounter an automobile experiencing issues because of below 5% wrong fuel contamination. Bear in mind that it is very rare - in no way impossible to find. You can get certain cars that don't stand any level of contamination at all.
    2. In between 2.9 and 5.8 litres of Diesel in the Hyundai (from 5 to 10%) is really a 50/50 condition. Our expertise demonstrates that as many people get away with this as those who break down. Any time you're deciding upon whether or not to chance it and just simply fill it up bear in mind that it is just like gambling it all on black - you have a 50/50 possibility of it working out.
    3. Anything more than 5.8 litres of Diesel in a Petrol Tucson really should right away be removed because your likelihood of getting away with this amount of contamination is in all likelihood less than one in fifty - truly long odds.
  2. Put some Diesel in a Petrol Hyundai and drove it: Have you noticed any performance issues ever since putting the incorrect fuel in the Tucson? If you have, have it drained no matter the amount of Diesel or the contamination ratio. Proceeding to run driving a motor vehicle that is currently starting to suffer from the effects of fuel contamination will probably only end up in progressively more harm being caused to your fuel system components.
  3. Would you like assurance?
    Then get it emptied. No matter the contamination ratio, there is always a certain level of risk linked with operating a Petrol motor on Petrol contaminated with Diesel. Probable consequences of driving on the wrong fuel can include the engine refusing to start, running unevenly, reduced power, degradation of the high-pressure pump, worn out or clogged injectors, etc. These are a few of the most frequently seen Diesel in Petrol symptoms, and should you observe any of them stop driving and get it drained right now.

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.
