Hyundai Fuel Drain


Putting Diesel in a Petrol Hyundai is a very common error. And exactly what you need to do about it depends on an assortment of factors. Assuming you want to find out what you ought to do to fix it then continue reading.
Let us discuss the most crucial factors to to consider whenever deciding on whether to have a fuel drain:

  1. What amount of Diesel did you put in the Hyundai, taking into account that the fuel tank capacity of the Hyundai Matrix is probably roughly 55 litres?
    1. Hardly any Diesel, something like 2.75 litres of Diesel in a Petrol Matrix will generally not be a major problem. Experience has shown us that quantities under 2.75 litres (which is about 5% of the fuel tank capacity) is frequently capable of being adequately diluted simply by completely topping up the tank with the right fuel.
      It's extremely unusual to come across a car or truck suffering from problems due to below 5% incorrect fuel contamination. Please remember it's infrequent - in no way impossible to find. There are actually certain automobiles that won't stand any level of contamination in the slightest.
    2. Somewhere between 2.75 and 5.5 litres of Diesel in the Hyundai (from 5 to 10%) is a 50/50 condition. Our working experience demonstrates that as many people get away with this as all those who don't. Whenever you are deciding whether to chance it and simply fill it up remember that it is just like betting everything on black - you've got a 50/50 chance of it working out.
    3. Anything above 5.5 litres of Diesel in a Petrol Matrix should straightaway be removed seeing that your probability of succeeding with that amount of contamination is in all likelihood lower than one in fifty - extremely huge odds.
  2. Put Diesel in a Petrol Hyundai and drove it: Have you seen any kind of performance problems after putting the incorrect fuel in your Matrix? If you have, have it drained regardless of the quantity of Diesel or even the contamination ratio. Continuing to drive driving a vehicle that is currently starting to suffer from the effect of fuel contamination will just be responsible for even more harm affecting your fuel system components.
  3. Are you interested in peace of mind?
    Then get it drained. No matter the contamination percentage, there is invariably some extent of risk in connection with operating a Petrol engine on fuel contaminated with the wrong fuel. Probable implications of driving a car on the wrong fuel normally include the motor not starting, running lumpy, losing power, degradation of the high-pressure pump, worn out or clogged injectors, and so forth. These are several of the most typical Diesel in Petrol signs and symptoms, and in the event that you notice any of them then stop and have it removed asap.

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.
