Kia Fuel Drain


Putting Petrol in a Diesel Kia is a regular error. And its solution varies according to several things. Assuming you want to know what to do to fix it then keep on reading.
Let us discuss the main variables to keep in mind when deciding on whether or not to get a fuel drain:

  1. What level of Petrol did you put into the Kia, considering that the fuel tank capacity of the Kia Sportage CRDi is in most cases around 58 litres?
    1. A modest quantity of Petrol, as little as 2.9 litres of Petrol in a Diesel Sportage CRDi will usually not be a big problem. Experience has shown us that an amount less than 2.9 litres (roughly 5% of the total fuel tank volume) is usually able to be adequately diluted by thoroughly filling the tank with the appropriate fuel.
      It is relatively unusual to encounter a vehicle suffering from problems with less than 5% incorrect fuel contamination. Bear in mind that it's infrequent - not impossible to encounter. You can get a number of cars that won't endure any amount of fuel contamination in the slightest.
    2. Anywhere between 2.9 and 5.8 litres of Petrol in the Kia (from 5 to 10%) is really a 50/50 situation. Our expertise demonstrates that as many people get away with this as all those who break down. Whenever deciding on whether or not to chance it and basically fill it up bear in mind that it is the same thing as betting it all on black - you will have a 50/50 possibility of it being ok.
    3. Anything more than 5.8 litres of Petrol in a Diesel Sportage CRDi should really right away be drained seeing as your probability of driving with that level of contamination is probably less than one in 50 - extremely big odds.
  2. Put Petrol in a Diesel Kia and drove it: Have you spotted any performance issues since putting the incorrect fuel in your Sportage CRDi? If you have, have it emptied regardless of the quantity of Petrol or the contamination percentage. Proceeding to drive driving a vehicle that is already beginning to suffer from the effects of wrong fuel contamination will just cause even more harm affecting the fuel system.
  3. Would you like assurance?
    Simply get it emptied. No matter the contamination ratio, there is always a certain level of danger associated with running a Diesel motor on Diesel contaminated with the wrong fuel. Possible consequences of driving on the wrong fuel include the motor refusing to start, running unevenly, losing power, degradation of the high-pressure pump, damaged or bunged injectors, and the like. These are several of the most typical Petrol in Diesel signs or symptoms, and should you detect any of them stop driving and get it removed immediately.

Petrol in Diesel FAQs

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.
