Hyundai Fuel Drain


Putting Petrol in a Diesel Hyundai is a very common mistake to make. And exactly what you want to do about it varies according to various things. In case you want to find out what you should do about this then stay with me.
These are the most crucial variables to think about when deciding on whether to get a fuel drain:

  1. What amount of Petrol did you put in to the Hyundai, taking into consideration that the fuel capacity of your Hyundai Sonata CRDi is in most cases about 70 litres?
    1. A small amount of Petrol, less than 3.5 litres of Petrol in a Diesel Sonata CRDi will quite often not necessarily be a major problem. Experience has taught us that anything less than 3.5 litres (approximately 5% of the overall fuel tank) is usually capable of being completely diluted by thoroughly filling up the rest of the tank with Diesel.
      It is relatively rare to come across an automobile suffering from issues due to below 5% wrong fuel contamination. Be aware that it is uncommon - certainly not impossible to find. There are actually certain automobiles that don't endure any amount of fuel contamination at all.
    2. In between 3.5 and 7 litres of Petrol in the Hyundai (5 to 10%) is a 50/50 scenario. Our expertise has shown us that as many people get away with it as those who break down. Any time you're figuring out whether to chance it and just simply top it up recognise that it is the same as gambling everything on black - you will have a 50/50 possibility of it working out.
    3. Anything more than 7 litres of Petrol in a Diesel Sonata CRDi really should immediately be drained out seeing that your probability of driving with that amount of contamination is certainly lower than one in 50 - extremely big odds.
  2. Put some Petrol in a Diesel Hyundai and drove it: Have you seen any kind of performance concerns ever since putting the incorrect fuel in your Sonata CRDi? If that's the case, have it drained irrespective of the quantity of Petrol or even the contamination ratio. Continually driving a vehicle that is already starting to suffer the effect of fuel contamination will definitely end up in progressively more harm being done to your fuel system parts.
  3. Are you looking for peace of mind?
    In that case get it removed. Regardless of the contamination ratio, there is inevitably some amount of danger caused by operating a Diesel vehicle on fuel contaminated with the incorrect fuel. Possible results of driving a car on the wrong fuel can include the engine refusing to start, running unevenly, lack of power, degradation of the high-pressure pump, damaged or bunged injectors, and the like. These are some of the commonest Petrol in Diesel signs or symptoms, and if you recognise any of them then stop and get it drained 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.
