Hyundai Fuel Drain


Putting Petrol in a Diesel Hyundai is a well-known mistake. And what you want to do about it will depend on a few factors. If perhaps you would like to find out what you have to do about it then please read on.
These are the main factors to to consider whenever making a decision whether or not to have the car drained:

  1. How much Petrol did you put into the Hyundai, taking into account that the fuel capacity of the Hyundai Grand Santa Fe is in most cases about 64 litres?
    1. Hardly any Petrol, less than 3.2 litres of Petrol in a Diesel Grand Santa Fe will in most cases not be a huge problem. Experience has taught us that quantities less than 3.2 litres (roughly 5% of the entire fuel tank) is sometimes able to be sufficiently diluted by means of completely topping the rest of the tank with the correct fuel.
      It is relatively rare to encounter a car or truck suffering from problems with below 5% wrong fuel contamination. Keep in mind it is rare - not impossible to encounter. There are certain cars that won't endure any level of fuel contamination in the slightest.
    2. Between 3.2 and 6.4 litres of Petrol in the Hyundai (5 to 10%) is really a 50/50 condition. Our expertise demonstrates that as many motorists get away with this as all those who don't. Whenever deciding on whether or not to chance it and just top it up bear in mind that it is the same as gambling it all on black - you've got a 50/50 possibility of it working out.
    3. Anything in excess of 6.4 litres of Petrol in your Diesel Grand Santa Fe should really promptly be drained out seeing as your probability of getting away with this amount of contamination is very likely lower than one in fifty - truly big odds.
  2. Put some Petrol in a Diesel Hyundai and drove it: Have you noted any kind of performance concerns after putting the incorrect fuel in your Grand Santa Fe? If you have, have it removed regardless of the quantity of Petrol or even the contamination percentage. Continuing to run running a vehicle that is beginning to suffer from the effect of fuel contamination will just cause more harm affecting the fuel system.
  3. Would you like assurance?
    In that case get it removed. Regardless of contamination ratio, there is invariably some degree of risk linked with driving a Diesel engine on fuel contaminated with the wrong fuel. Possible outcomes of driving a car on the incorrect fuel normally include the motor not starting, running unevenly, reduced power, wearing of the high-pressure pump, damaged or bunged injectors, and so on. These are a few of the most typical Petrol in Diesel signs and symptoms, and in the event that you notice any of them stop and have it drained right away.

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.
