Hyundai Fuel Drain


Filling Petrol in a Diesel Hyundai is a fairly typical error. And its solution varies according to a few things. In case you would like to find out what you should do to sort it out then stay with me.
Here are the most important variables to consider whenever deciding whether to have a fuel drain:

  1. What level of Petrol have you put in the Hyundai, taking into consideration that the fuel tank capacity of your Hyundai H-1 Starex TD is normally around 65 litres?
    1. A tiny quantity of Petrol, less than 3.25 litres of Petrol in a Diesel H-1 Starex TD will quite often not necessarily be a big problem. Experience has proven to us that quantities less than 3.25 litres (5% of the whole fuel tank capacity) is frequently capable of being sufficiently diluted by means of entirely topping up the remainder of the tank with Diesel.
      It's very rare to come across a motor vehicle having difficulties because of under 5% incorrect fuel contamination. Remember that it is unusual - not impossible to find. There are a number of vehicles that don't endure any level of fuel contamination at all.
    2. Between 3.25 and 6.5 litres of Petrol in the Hyundai (from 5 to 10%) is more of a 50/50 condition. Our expertise has confirmed that as many people get away with it as those who don't. Any time you are deciding whether to chance it and just fill it up recognise that it is exactly like gambling it all on black - you have got a 50/50 chance of it working out.
    3. Anything above 6.5 litres of Petrol in a Diesel H-1 Starex TD should really promptly be drained because your likelihood of driving with that quantity of contamination is more than likely below one in 50 - definitely long odds.
  2. Put Petrol in a Diesel Hyundai and drove it: Have you noticed any kind of performance issues after putting the bad fuel in the H-1 Starex TD? If that's the case, get it emptied irrespective of the volume of Petrol or the contamination percentage. Still driving a car that is already starting to suffer the effects of fuel contamination can definitely lead to more damage being caused to your fuel system components.
  3. Are you looking for reassurance?
    Simply get it emptied. No matter the contamination percentage, there is invariably some extent of threat connected to running a Diesel engine on Diesel contaminated with Petrol. Probable implications of driving on the incorrect fuel include things like the engine refusing to start, running lumpy, losing power, degradation of the high-pressure pump, worn out or bunged injectors, etc. These are some of the most frequently seen Petrol in Diesel signs and symptoms, and in the event that you notice any of them stop and have it drained immediately.

Petrol in Diesel FAQs

When someone has put Petrol in a Diesel car they have a few very common questions. So we have compiled a list of the most Frequently Asked Questions for you

I put Petrol in a Diesel 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 Diesel car on Petrol 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 Petrol can I get away with in a Diesel 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 Diesel 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.
