Kia Fuel Drain


Filling up with Diesel in a Petrol Kia is a regularly occurring mistake. And what you need to do about it is based on an assortment of things. If perhaps you would like to know what you have to do about this then read on.
Listed below are the most important variables to think about whenever deciding on whether or not to have a fuel drain:

  1. What amount of Diesel did you put in the Kia, bearing in mind that the fuel capacity of the Kia Magentis is in most cases around 65 litres?
    1. A modest amount of Diesel, something like 3.25 litres of Diesel in a Petrol Magentis will most of the time not necessarily be a massive problem. Experience has shown us that quantities under 3.25 litres (which is close to 5% of the total fuel tank capacity) is usually capable of being sufficiently diluted through totally filling the rest of the tank with Petrol.
      It's extremely rare to find a car or truck suffering from difficulties with below 5% wrong fuel contamination. Remember that it's unusual - definitely not impossible to find. There are some automobiles that don't endure any amount of contamination in the slightest.
    2. Between 3.25 and 6.5 litres of Diesel in the Kia (5 to 10%) is more of a 50/50 scenario. Our expertise has revealed that as many motorists get away with this as those who break down. Whenever you are deciding on whether to chance it and basically fill it up consider that it is the same thing as wagering it all on black - you have got a 50/50 chance of it being ok.
    3. Anything above 6.5 litres of Diesel in your Petrol Magentis should really promptly be removed since your probability of getting away with this level of contamination is very likely less than one in fifty - really big odds.
  2. Put Diesel in a Petrol Kia and drove it: Have you spotted any kind of performance concerns after putting the wrong fuel in the Magentis? If that's the case, have it emptied no matter the quantity of Diesel or even the contamination ratio. Continuing to run running a motor vehicle that is now starting to suffer from the effect of fuel contamination can definitely end up in increasing amounts of harm being caused to the fuel system components.
  3. Do you want reassurance?
    Then get it emptied. Regardless of contamination ratio, there is invariably a certain level of danger caused by driving a Petrol motor on Petrol contaminated with Diesel. Likely implications of driving a car on the incorrect fuel normally include the motor refusing to start, running unevenly, reduced power, wearing of the high-pressure pump, worn or blocked injectors, etc. These are a few of the most common Diesel in Petrol symptoms, and should you recognise any of them stop and get it drained right now.

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.
