Hyundai Fuel Drain


Putting Diesel in a Petrol Hyundai is a fairly typical problem. And its remedy is based on a number of factors. In the event that you would like to know what to do to fix it then keep reading.
Here are the most crucial factors to think about when deciding on whether or not to get the car drained:

  1. How much Diesel did you put in the Hyundai, keeping in mind that the fuel capacity of your Hyundai Genesis is usually approximately 65 litres?
    1. A tiny quantity of Diesel, something like 3.25 litres of Diesel in a Petrol Genesis will typically not really be a major problem. Experience has shown us that an amount less than 3.25 litres (which is approximately 5% of the whole fuel tank) is often able to be completely diluted through completely topping the remainder of the tank with the appropriate fuel.
      It's rather rare to come across a vehicle suffering from issues with less than 5% incorrect fuel contamination. Keep in mind that it is very uncommon - certainly not impossible to encounter. There are some cars that won't stand any degree of fuel contamination in the slightest.
    2. In between 3.25 and 6.5 litres of Diesel in the Hyundai (5 to 10%) is more of a 50/50 condition. Our practical experience has shown us that as many people get away with this as those who don't. Whenever you are figuring out whether or not to chance it and basically fill it up remember that it is the same thing as betting your car on black - you've got a 50/50 chance of it working.
    3. Anything in excess of 6.5 litres of Diesel in a Petrol Genesis should really immediately be removed since your likelihood of driving with this amount of contamination is very likely below one in 50 - genuinely big odds.
  2. Put some Diesel in a Petrol Hyundai and drove it: Have you noticed any kind of performance difficulties as a result of putting the bad fuel in your Genesis? If you have, get it emptied regardless of the amount of Diesel or even the contamination percentage. Continually running an automobile that is now starting to suffer from the effects of fuel contamination will probably typically end up in increasing amounts of damage affecting the fuel system.
  3. Are you looking for peace of mind?
    You should get it emptied. Whatever the contamination ratio, there is inevitably some amount of danger associated with driving a Petrol engine on fuel contaminated with the wrong fuel. Possible consequences of driving a car on the wrong fuel can include the engine refusing to start, running lumpy, losing power, degradation of the high-pressure pump, worn out or blocked injectors, etc. These are a few of the most typical Diesel in Petrol signs and symptoms, and if you notice any of them stop and have it drained as soon as possible.

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.
