Seat Fuel Drain


Putting Petrol in a Diesel Seat is a common problem. And exactly what you want to do about it depends on an assortment of factors. Assuming you would like to find out what it is best to do about it then read on.
Let us discuss the key factors to think about whenever choosing whether or not to get a fuel drain:

  1. How much Petrol did you put in the Seat, keeping in mind that the fuel capacity of the Seat Altea Freetrack TDI is usually roughly 55 litres?
    1. Hardly any Petrol, less than 2.75 litres of Petrol in a Diesel Altea Freetrack TDI will normally not really be a major problem. Experience has demonstrated to us that anything under 2.75 litres (which is about 5% of the total fuel tank) is quite often able to be sufficiently diluted by thoroughly filling up the tank with the appropriate fuel.
      It's very unusual to encounter a car or truck experiencing problems due to under 5% wrong fuel contamination. Remember that it is infrequent - definitely not impossible to find. You will discover certain cars that won't stand any degree of fuel contamination in the slightest.
    2. Between 2.75 and 5.5 litres of Petrol in the Seat (5 to 10%) is more of a 50/50 scenario. Our practical experience has demonstrated that as many drivers get away with it as those who don't. Any time you are deciding upon whether or not to risk it and just top it up consider that it is the same thing as wagering everything on black - you have a 50/50 chance of it working.
    3. Anything above 5.5 litres of Petrol in a Diesel Altea Freetrack TDI should really immediately be drained out seeing as your likelihood of succeeding with this quantity of contamination is probably lower than one in fifty - definitely big odds.
  2. Put Petrol in a Diesel Seat and drove it: Have you spotted any performance troubles as a result of putting the wrong fuel in your Altea Freetrack TDI? If you have, have it emptied regardless of the quantity of Petrol or the contamination ratio. Continuing to drive driving a car that is beginning to suffer from the consequences of fuel contamination will definitely bring about more damage being caused to your fuel system components.
  3. Do you need assurance?
    You should get it emptied. Regardless of contamination percentage, there is always some extent of danger connected to running a Diesel vehicle on fuel contaminated with Petrol. Possible consequences of driving a vehicle on the wrong fuel can include the engine refusing to start, running lumpy, reduced power, wearing of the high-pressure pump, worn or blocked injectors, and the like. These are a few of the most frequently seen Petrol in Diesel symptoms, and if you recognise any of them stop driving and have it removed 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.
