Hyundai Fuel Drain


Filling Petrol in a Diesel Hyundai is a common error. And its solution varies according to several different things. If you want to know what you need to do to sort it out then read on.
Let us discuss the main factors to take into consideration when choosing whether to have a fuel drain:

  1. How much Petrol have you put in the Hyundai, taking into account that the fuel capacity of your Hyundai Santa Fe CRDi is normally around 65 litres?
    1. Hardly any Petrol, something like 3.25 litres of Petrol in a Diesel Santa Fe CRDi will most of the time not be a massive problem. Experience has proven to us that an amount less than 3.25 litres (which is approximately 5% of the fuel tank) is quite often capable of being sufficiently diluted by wholly filling the tank with Diesel.
      It's extremely unusual to come across a car going through issues due to lower than 5% wrong fuel contamination. Be aware that it's infrequently found - in no way impossible to encounter. There are a few automobiles that don't stand any level of fuel contamination whatsoever.
    2. Somewhere between 3.25 and 6.5 litres of Petrol in the Hyundai (from 5 to 10%) is a 50/50 condition. Our working experience demonstrates that as many people get away with it as those who break down. Any time you are deciding on whether to chance it and just simply top it up bear in mind that it is exactly like betting everything on black - you have a 50/50 chance of it working.
    3. Anything more than 6.5 litres of Petrol in a Diesel Santa Fe CRDi ought to as soon as possible be removed because your likelihood of succeeding with this quantity of contamination is certainly below one in 50 - seriously big odds.
  2. Put some Petrol in a Diesel Hyundai and drove it: Have you noticed any performance troubles ever since putting the bad fuel in your Santa Fe CRDi? If so, have it emptied regardless of the volume of Petrol or the contamination ratio. Still running a car that is already beginning to suffer from the effects of fuel contamination will definitely bring about increasing amounts of damage affecting your fuel system components.
  3. Do you want assurance?
    Then simply just get it drained. Regardless of contamination percentage, there is invariably a certain level of danger affiliated with driving a Diesel vehicle on Diesel contaminated with the incorrect fuel. Probable implications of driving on the wrong fuel include things like the engine refusing to start, running unevenly, loss of power, wearing of the high-pressure pump, worn out or clogged injectors, and so forth. These are a few of the most common Petrol in Diesel signs or symptoms, and in the event that you recognise any of them stop driving and get it removed asap.

Petrol in Diesel Questions

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.
