Seat Fuel Drain


Putting Diesel in a Petrol Seat is a regularly occurring mistake. And what you need to do about it varies according to a few things. If perhaps you want to find out what you have to do about this then please read on.
Listed below are the main factors to to consider whenever making a decision whether or not to have a fuel drain:

  1. What amount of Diesel have you put into the Seat, keeping in mind that the fuel capacity of the Seat Ibiza is probably roughly 45 litres?
    1. A tiny quantity of Diesel, less than 2.25 litres of Diesel in a Petrol Ibiza will typically not really be a big problem. Experience has proven to us that anything under 2.25 litres (almost 5% of the total fuel tank) is usually capable of being adequately diluted by means of wholly filling up the rest of the tank with the correct fuel.
      It is quite unusual to come across a car or truck experiencing problems because of less than 5% incorrect fuel contamination. Remember that it's unusual - not impossible to encounter. You can get some motor vehicles that will not stand any level of contamination whatsoever.
    2. Anywhere between 2.25 and 4.5 litres of Diesel in the Seat (from 5 to 10%) is really a 50/50 situation. Our experience has shown us that as many drivers get away with this as those who don't. Any time you are trying to decide whether or not to risk it and just simply top it up bear in mind that it is the same as gambling your car on black - you will have a 50/50 chance of it working.
    3. Anything above 4.5 litres of Diesel in your Petrol Ibiza really should promptly be drained since your probability of succeeding with this amount of contamination is in all likelihood less than one in fifty - definitely big odds.
  2. Put Diesel in a Petrol Seat and drove it: Have you seen any kind of performance difficulties after putting the incorrect fuel in your Ibiza? If you have, have it emptied no matter the amount of Diesel or the contamination ratio. Continually driving a vehicle that is already starting to suffer the effects of fuel contamination will just lead to progressively more harm affecting the fuel system.
  3. Are you interested in assurance?
    Then get it removed. Whatever the contamination percentage, there is invariably a certain level of risk caused by driving a Petrol vehicle on Petrol contaminated with Diesel. Possible final outcomes of driving on the incorrect fuel include the engine refusing to start, running unevenly, losing power, wearing of the high-pressure pump, worn or clogged injectors, etc. These are some of the most typical Diesel in Petrol warning signs, and in the event that you detect any of them then stop and have it drained right away.

Diesel in Petrol FAQs

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.
