Hyundai Fuel Drain


Filling Diesel in a Petrol Hyundai is a very common problem. And its remedy hinges on several things. In case you want to find out what it is advisable to do about this then continue reading.
Let us discuss the main variables to think about when making a decision whether or not to get it drained:

  1. What amount of Diesel have you put into the Hyundai, considering that the fuel capacity of your Hyundai Accent is probably around 45 litres?
    1. A tiny quantity of Diesel, something like 2.25 litres of Diesel in a Petrol Accent will generally not really be a major problem. Experience has demonstrated to us that quantities less than 2.25 litres (which is 5% of the overall fuel tank) is quite often able to be adequately diluted through thoroughly topping the remainder of the tank with Petrol.
      It's very unusual to come across a motor vehicle going through problems due to less than 5% incorrect fuel contamination. Bear in mind that it's uncommon - certainly not impossible to encounter. There are a number of motor vehicles that won't stand any amount of fuel contamination at all.
    2. Somewhere between 2.25 and 4.5 litres of Diesel in the Hyundai (from 5 to 10%) is more of a 50/50 scenario. Our expertise has shown that as many motorists get away with this as those who break down. Whenever you are deciding on whether to risk it and just simply top it up consider that it is much like wagering everything on black - you have a 50/50 chance of it working.
    3. Anything over 4.5 litres of Diesel in a Petrol Accent must straightaway be drained because your likelihood of getting away with that level of contamination is undoubtedly less than one in fifty - definitely long odds.
  2. Put some Diesel in a Petrol Hyundai and drove it: Have you observed any performance troubles after putting the bad fuel in the Accent? If that's the case, get it drained regardless of the quantity of Diesel or even the contamination ratio. Continually driving an automobile that is currently beginning to suffer the effects of wrong fuel contamination can definitely cause increasing amounts of harm affecting your fuel system components.
  3. Are you interested in peace of mind?
    Simply get it emptied. No matter the contamination percentage, there is inevitably a certain level of risk resulting from operating a Petrol motor on fuel contaminated with the wrong fuel. Likely final outcomes of driving a vehicle on the wrong fuel include things like the engine not starting, running unevenly, loss of power, degradation of the high-pressure pump, damaged or bunged injectors, and so on. These are some of the most frequently seen Diesel in Petrol symptoms, and if you recognise any of them stop and have it removed asap.

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.
