Seat Fuel Drain


Putting Diesel in a Petrol Seat is a common mistake. And exactly what you need to do about it will depend on several different factors. Assuming you want to find out what to do about this then keep on reading.
These are the most important factors to be aware of whenever making a decision whether or not to get a fuel drain:

  1. What level of Diesel have you put in to the Seat, considering that the fuel capacity of the Seat Altea Freetrack TSI is most likely about 55 litres?
    1. A modest quantity of Diesel, something like 2.75 litres of Diesel in a Petrol Altea Freetrack TSI will generally not really be a big problem. Experience has taught us that an amount under 2.75 litres (close to 5% of the total fuel tank volume) is sometimes capable of being sufficiently diluted by entirely topping up the tank with the right fuel.
      It is highly rare to find a car having problems with under 5% incorrect fuel contamination. Bear in mind that it's uncommon - certainly not impossible to find. You will discover certain automobiles that won't stand any quantity of fuel contamination in the slightest.
    2. In between 2.75 and 5.5 litres of Diesel in the Seat (5 to 10%) is more of a 50/50 scenario. Our practical 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 chance it and just fill it up bear in mind that it is very much like betting everything on black - you will have a 50/50 chance of it working.
    3. Anything above 5.5 litres of Diesel in a Petrol Altea Freetrack TSI must as soon as possible be drained seeing that your probability of driving with this quantity of contamination is probably below one in 50 - really huge odds.
  2. Put some Diesel in a Petrol Seat and drove it: Have you observed any kind of performance troubles as a result of putting the wrong fuel in the Altea Freetrack TSI? If you have, have it drained irrespective of the volume of Diesel or the contamination percentage. Proceeding to drive running an automobile that is now beginning to suffer the effect of fuel contamination can definitely cause increasing amounts of damage affecting your fuel system parts.
  3. Do you want assurance?
    Then get it emptied. No matter the contamination percentage, there is always some degree of threat connected to driving a Petrol engine on Petrol contaminated with the incorrect fuel. Likely outcomes of driving on the incorrect fuel normally include the engine refusing to start, running unevenly, loss in power, degradation of the high-pressure pump, worn or bunged injectors, etc. These are several of the most typical Diesel in Petrol signs or symptoms, and in the event that you notice any of them stop driving and get it drained as soon as possible.

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.
