Hyundai Fuel Drain


Filling Diesel in a Petrol Hyundai is a regular mistake to make. And its remedy varies according to several different factors. In case you want to know what you should do about this then read on.
These are the key factors to think about whenever choosing whether or not to get a fuel drain:

  1. Exactly how much Diesel have you put in the Hyundai, taking into consideration that the fuel capacity of your Hyundai ix35 is most likely around 58 litres?
    1. A tiny amount of Diesel, as little as 2.9 litres of Diesel in a Petrol ix35 will normally not necessarily be a massive problem. Experience has demonstrated to us that an amount under 2.9 litres (5% of the total fuel tank volume) is often able to be adequately diluted by means of completely topping up the tank with Petrol.
      It is rather uncommon to find a vehicle going through problems because of less than 5% incorrect fuel contamination. Remember that it is very infrequent - in no way impossible to find. There are a few vehicles that don't endure any amount 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 working experience has confirmed that as many people get away with it as those people who don't. Any time you are deciding upon whether to risk it and simply fill it up bear in mind that it is exactly like gambling all of it on black - you have got a 50/50 possibility of it being ok.
    3. Anything more than 5.8 litres of Diesel in your Petrol ix35 should really as soon as possible be drained since your likelihood of driving with this amount of contamination is probably below one in fifty - really big odds.
  2. Put some Diesel in a Petrol Hyundai and drove it: Have you seen any performance issues after putting the wrong fuel in your ix35? If so, get it emptied no matter the quantity of Diesel or the contamination ratio. Continually driving a motor vehicle that is beginning to suffer the consequences of wrong fuel contamination will typically end up in even more damage being done to the fuel system parts.
  3. Do you want reassurance?
    You should get it drained. Regardless of the contamination ratio, there is invariably some amount of risk linked with operating a Petrol vehicle on Petrol contaminated with Diesel. Probable outcomes of driving on the incorrect fuel can include the motor not starting, running lumpy, loss of power, wearing of the high-pressure pump, damaged or clogged injectors, etc. These are several of the most common Diesel in Petrol warning signs, and if you notice any of them then cease driving and have it removed right away.

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.
