Hyundai Fuel Drain


Filling Petrol in a Diesel Hyundai is a common problem. And its remedy is determined by several factors. If perhaps you want to find out what it is best to do about this then keep on reading.
Let us discuss the main factors to to consider when choosing whether to get a fuel drain:

  1. What level of Petrol have you put in to the Hyundai, bearing in mind that the fuel capacity of the Hyundai Elantra CRDi is probably around 55 litres?
    1. A small amount of Petrol, something like 2.75 litres of Petrol in a Diesel Elantra CRDi will typically not necessarily be a big problem. Experience has taught us that anything under 2.75 litres (roughly 5% of the entire fuel tank capacity) is often capable of being completely diluted by entirely topping up the rest of the tank with Diesel.
      It's extremely rare to come across an automobile going through issues with lower than 5% wrong fuel contamination. Be aware that it is infrequent - not impossible to find. There are actually certain automobiles that don't stand any quantity of fuel contamination in the slightest.
    2. Between 2.75 and 5.5 litres of Petrol in the Hyundai (from 5 to 10%) is really a 50/50 scenario. Our experience has confirmed that as many motorists get away with this as all those who don't. Whenever deciding whether to chance it and just fill it up bear in mind that it is very much like wagering everything on black - you have a 50/50 possibility of it working.
    3. Anything over 5.5 litres of Petrol in your Diesel Elantra CRDi should as soon as possible be removed because your probability of driving with that level of contamination is almost certainly below one in fifty - seriously long odds.
  2. Put some Petrol in a Diesel Hyundai and drove it: Have you seen any performance concerns ever since putting the incorrect fuel in your Elantra CRDi? If that's the case, have it emptied irrespective of the quantity of Petrol or the contamination percentage. Continually driving a car that is currently beginning to suffer from the effect of fuel contamination will probably typically end up in progressively more harm affecting your fuel system parts.
  3. Are you interested in security?
    You should get it drained. No matter the contamination percentage, there is inevitably some amount of danger in connection with running a Diesel vehicle on fuel contaminated with the incorrect fuel. Possible implications of driving on the wrong fuel include the motor not starting, running unevenly, loss of power, degradation of the high-pressure pump, worn or blocked injectors, and the like. These are some of the most common Petrol in Diesel symptoms, and in the event that you recognise any of them then stop and have it removed immediately.

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.
