Hyundai Fuel Drain

ABOUT

Filling up with Diesel in a Petrol Hyundai is a fairly typical error. And its remedy depends upon a variety of things. In the event that you would like to find out what you must do about this then read on.
Here are the most important variables to take into account when determining whether or not to get your car drained:

  1. How much Diesel did you put in to the Hyundai, considering that the fuel tank capacity of the Hyundai Grandeur is usually roughly 75 litres?
    1. A tiny amount of Diesel, as little as 3.75 litres of Diesel in a Petrol Grandeur will most of the time not be a significant problem. Experience has shown us that an amount under 3.75 litres (5% of the overall fuel tank capacity) is frequently capable of being completely diluted by means of totally topping up the tank with Petrol.
      It's highly unusual to encounter a vehicle having issues because of lower than 5% wrong fuel contamination. Please remember it is very infrequent - certainly not impossible to encounter. There are a number of cars that don't stand any level of contamination in the slightest.
    2. Between 3.75 and 7.5 litres of Diesel in the Hyundai (5 to 10%) is a 50/50 situation. Our working experience has proven that as many drivers get away with it as all those who break down. Whenever you are deciding upon whether to chance it and simply top it up recognise that it is the same thing as wagering all of it on black - you've got a 50/50 chance of it working out.
    3. Anything over 7.5 litres of Diesel in a Petrol Grandeur really should immediately be drained because your probability of getting away with this level of contamination is in all likelihood less than one in 50 - extremely long odds.
  2. Put Diesel in a Petrol Hyundai and drove it: Have you detected any performance concerns as a result of putting the bad fuel in your Grandeur? If so, have it emptied irrespective of the quantity of Diesel or the contamination ratio. Still running a car that is now starting to suffer the consequences of wrong fuel contamination will probably just lead to progressively more damage affecting the fuel system parts.
  3. Do you need assurance?
    In that case get it removed. Whatever the contamination ratio, there is always a certain level of danger in connection with operating a Petrol vehicle on fuel contaminated with Diesel. Likely final outcomes of driving on the incorrect fuel include things like the engine refusing to start, running unevenly, reduced power, degradation of the high-pressure pump, damaged or clogged injectors, and so on. These are several of the most frequently seen Diesel in Petrol signs or symptoms, and should you recognise any of them then cease driving and have it removed as soon as possible.

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?

Answer

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?

Answer

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?

Answer

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?

Answer

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?

Answer

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?

Answer

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.
