Seat Fuel Drain


Filling Diesel in a Petrol Seat is a regularly occurring mistake. And exactly what you want to do about it is determined by a number of factors. In case you would like to know what you should do about this then stay with me.
These are the most important factors to take into account whenever determining whether or not to get a fuel drain:

  1. Exactly how much Diesel did you put into the Seat, bearing in mind that the fuel tank capacity of your Seat Leon is usually about 55 litres?
    1. A small quantity of Diesel, something like 2.75 litres of Diesel in a Petrol Leon will typically not really be a huge problem. Experience has demonstrated to us that anything less than 2.75 litres (which is roughly 5% of the entire fuel tank capacity) is generally capable of being adequately diluted by thoroughly topping the remainder of the tank with the appropriate fuel.
      It is relatively unusual to come across an automobile going through issues due to below 5% incorrect fuel contamination. Remember that it's infrequently found - not impossible to encounter. You can get certain motor vehicles that won't endure any amount of fuel contamination whatsoever.
    2. Anywhere between 2.75 and 5.5 litres of Diesel in the Seat (from 5 to 10%) is a 50/50 scenario. Our expertise has shown us that as many people get away with this as those people who break down. Any time you are figuring out whether to chance it and just top it up consider that it is much like gambling it all on black - you have a 50/50 possibility of it working.
    3. Anything above 5.5 litres of Diesel in a Petrol Leon must promptly be drained seeing that your likelihood of getting away with this level of contamination is almost certainly lower than one in fifty - genuinely huge odds.
  2. Put some Diesel in a Petrol Seat and drove it: Have you noticed any kind of performance difficulties since putting the bad fuel in the Leon? In that case, get it emptied regardless of the amount of Diesel or even the contamination percentage. Continuing to run driving an automobile that is already starting to suffer the effects of wrong fuel contamination can definitely lead to more and more damage being done to the fuel system parts.
  3. Do you want peace of mind?
    Then simply just get it removed. Whatever the contamination percentage, there is invariably a certain level of danger associated with driving a Petrol engine on fuel contaminated with Diesel. Likely outcomes of driving a car on the wrong fuel normally include the motor refusing to start, running unevenly, losing power, degradation of the high-pressure pump, worn or clogged injectors, and so forth. These are some of the most common Diesel in Petrol signs and symptoms, and if you detect any of them stop and get it removed asap.

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.
