Kia Fuel Drain


Filling up with Petrol in a Diesel Kia is a very common problem. And exactly what you have to do about it will depend on various things. In the event that you want to know what it is advisable to do to fix it then continue reading.
Listed below are the most important factors to keep in mind when making a decision whether to get a fuel drain:

  1. Exactly how much Petrol have you put into the Kia, bearing in mind that the fuel tank capacity of the Kia Optima CRDi is probably roughly 70 litres?
    1. A tiny amount of Petrol, less than 3.5 litres of Petrol in a Diesel Optima CRDi will quite often not really be a significant problem. Experience has proven to us that quantities under 3.5 litres (which is 5% of the fuel tank volume) is sometimes capable of being sufficiently diluted simply by completely topping up the remainder of the tank with Diesel.
      It's highly uncommon to encounter a motor vehicle having problems with less than 5% incorrect fuel contamination. Keep in mind it is very uncommon - in no way impossible to find. You will discover some automobiles that won't endure any amount of contamination in the slightest.
    2. Anywhere between 3.5 and 7 litres of Petrol in the Kia (from 5 to 10%) is more of a 50/50 scenario. Our working experience demonstrates that as many motorists get away with it as all those who don't. Whenever deciding on whether to risk it and just simply top it up remember that it is just like betting your car on black - you will have a 50/50 chance of it working out.
    3. Anything over 7 litres of Petrol in a Diesel Optima CRDi must as soon as possible be drained seeing as your likelihood of succeeding with this level of contamination is in all likelihood below one in 50 - seriously long odds.
  2. Put Petrol in a Diesel Kia and drove it: Have you seen any kind of performance concerns as a result of putting the wrong fuel in the Optima CRDi? If you have, have it removed irrespective of the quantity of Petrol or the contamination percentage. Continually running a car that is currently beginning to suffer the effect of wrong fuel contamination can definitely result in more and more harm affecting your fuel system components.
  3. Would you like assurance?
    Then get it emptied. Regardless of the contamination ratio, there is inevitably some extent of danger associated with driving a Diesel vehicle on Diesel contaminated with Petrol. Likely outcomes of driving a car on the incorrect fuel normally include the motor not starting, running lumpy, loss in power, degradation of the high-pressure pump, worn or blocked injectors, and so forth. These are several of the most common Petrol in Diesel signs or symptoms, and if you recognise any of them then stop driving and get it removed right away.

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.
