Seat Fuel Drain


Filling up with Petrol in a Diesel Seat is a fairly typical error. And its remedy depends upon a variety of things. In case you want to know what it is advisable to do to fix it then please read on.
Listed below are the key variables to keep in mind when determining whether or not to get a fuel drain:

  1. Exactly how much Petrol did you put in the Seat, taking into account that the fuel tank capacity of the Seat Exeo TDI is usually approximately 70 litres?
    1. A modest amount of Petrol, less than 3.5 litres of Petrol in a Diesel Exeo TDI will normally not be a massive problem. Experience has taught us that anything under 3.5 litres (which is close to 5% of the entire fuel tank) is generally capable of being sufficiently diluted by means of entirely filling up the remainder of the tank with Diesel.
      It is pretty rare to find a motor vehicle experiencing difficulties because of below 5% wrong fuel contamination. Please remember it is very infrequently found - definitely not impossible to encounter. You can get a few vehicles that will not stand any level of contamination in the slightest.
    2. Anywhere between 3.5 and 7 litres of Petrol in the Seat (from 5 to 10%) is more of a 50/50 situation. Our working experience has revealed that as many motorists get away with it as those people who don't. Any time you're trying to decide whether to risk it and just fill it up remember that it is the same as gambling everything on black - you have a 50/50 possibility of it working.
    3. Anything above 7 litres of Petrol in your Diesel Exeo TDI really should promptly be drained seeing as your probability of succeeding with this amount of contamination is very likely lower than one in fifty - seriously big odds.
  2. Put Petrol in a Diesel Seat and drove it: Have you seen any performance troubles ever since putting the incorrect fuel in the Exeo TDI? If you have, get it drained no matter the volume of Petrol or the contamination percentage. Proceeding to drive running an automobile that is already starting to suffer the consequences of wrong fuel contamination can typically end up in more harm affecting the fuel system components.
  3. Would you like peace of mind?
    In that case get it emptied. Regardless of contamination percentage, there is invariably some extent of danger connected with driving a Diesel motor on Diesel contaminated with Petrol. Likely consequences of driving on the incorrect fuel can include the engine refusing to start, running lumpy, loss in power, degradation of the high-pressure pump, damaged or bunged injectors, and so forth. These are several of the most common Petrol in Diesel signs or symptoms, and should you notice any of them then stop and get it drained right now.

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.
