Kia Fuel Drain


Filling Petrol in a Diesel Kia is a fairly typical mistake to make. And its solution depends on a number of factors. If perhaps you would like to know what you have to do to fix it then keep reading.
Let us discuss the main variables to think about when making a decision whether or not to get a fuel drain:

  1. How much Petrol have you put in the Kia, bearing in mind that the fuel tank capacity of your Kia Carnival CRDi is in most cases roughly 75 litres?
    1. A small quantity of Petrol, something like 3.75 litres of Petrol in a Diesel Carnival CRDi will more often than not not really be a massive problem. Experience has shown us that anything under 3.75 litres (which is almost 5% of the overall fuel tank) is in many instances able to be adequately diluted through totally topping up the rest of the tank with the right fuel.
      It's extremely uncommon to encounter a car experiencing difficulties because of less than 5% incorrect fuel contamination. Keep in mind that it's uncommon - definitely not impossible to encounter. There are a few vehicles that don't endure any quantity of contamination in the slightest.
    2. Somewhere between 3.75 and 7.5 litres of Petrol in the Kia (5 to 10%) is really a 50/50 situation. Our practical experience has shown us that as many people get away with this as those people who break down. Whenever you are deciding on whether or not to chance it and just fill it up recognise that it is exactly like betting your car on black - you have a 50/50 chance of it working out.
    3. Anything above 7.5 litres of Petrol in a Diesel Carnival CRDi must straightaway be drained out seeing that your probability of getting away with that quantity of contamination is probably less than one in fifty - extremely long odds.
  2. Put Petrol in a Diesel Kia and drove it: Have you noted any kind of performance concerns after putting the incorrect fuel in your Carnival CRDi? If that's the case, get it drained irrespective of the volume of Petrol or even the contamination ratio. Continually running a car that is beginning to suffer from the effects of wrong fuel contamination will just cause increasing amounts of harm affecting the fuel system.
  3. Do you need reassurance?
    Simply get it drained. Regardless of the contamination ratio, there is inevitably some amount of risk affiliated with running a Diesel engine on fuel contaminated with the incorrect fuel. Probable outcomes of driving on the incorrect fuel normally include the motor refusing to start, running lumpy, losing power, degradation of the high-pressure pump, worn or clogged injectors, and the like. These are a few of the most common Petrol in Diesel signs and symptoms, and if you recognise any of them stop and get it drained immediately.

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.
