Kia Fuel Drain


Filling up with Diesel in a Petrol Kia is a regular error. And its solution hinges on several things. In case you want to find out what it is best to do to fix it then continue reading.
Here are the most important factors to take into account when deciding whether to have a fuel drain:

  1. How much Diesel did you put in to the Kia, taking into consideration that the fuel capacity of the Kia Cerato is in most cases about 55 litres?
    1. A small quantity of Diesel, as little as 2.75 litres of Diesel in a Petrol Cerato will more often than not not necessarily be a huge problem. Experience has shown us that anything less than 2.75 litres (approximately 5% of the entire fuel tank capacity) is in many instances able to be completely diluted simply by entirely topping up the rest of the tank with the correct fuel.
      It is relatively uncommon to find a car or truck experiencing problems due to lower than 5% incorrect fuel contamination. Keep in mind that it is unusual - in no way impossible to find. You can get a few cars that will not stand any degree of fuel contamination in the slightest.
    2. Somewhere between 2.75 and 5.5 litres of Diesel in the Kia (5 to 10%) is really a 50/50 scenario. Our experience has demonstrated that as many people get away with this as those people who break down. When deciding on whether or not to risk it and simply fill it up remember that it is the same as gambling your car on black - you have a 50/50 possibility of it working.
    3. Anything more than 5.5 litres of Diesel in a Petrol Cerato really should straight away be drained seeing that your probability of succeeding with this quantity of contamination is more than likely less than one in fifty - seriously big odds.
  2. Put some Diesel in a Petrol Kia and drove it: Have you detected any performance difficulties after putting the wrong fuel in your Cerato? If you have, get it drained regardless of the volume of Diesel or even the contamination ratio. Still driving a vehicle that is now starting to suffer the effect of fuel contamination will definitely bring about more harm being caused to your fuel system components.
  3. Are you interested in peace of mind?
    Then get it removed. No matter the contamination percentage, there is inevitably some amount of danger in connection with operating a Petrol engine on Petrol contaminated with Diesel. Likely results of driving a car on the incorrect fuel include the motor not starting, running lumpy, loss in power, degradation of the high-pressure pump, worn or blocked injectors, and so on. These are some of the most typical Diesel in Petrol warning signs, and should you observe any of them stop and get it removed right now.

Diesel in Petrol FAQs

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.
