Put Petrol in a Diesel Seat Ibiza 1.9 SDi SE?

If you've gone and put the wrong fuel in your Seat you probably want to know what you should do about it. The answer to this question depends on the quantity of Petrol you put in your Diesel car.

The first thing we need to look at is the Seat's fuel tank capacity. So, what is the fuel capacity of a 1.9-litre Diesel Ibiza 1.9 SDi SE? The answer is: the fuel tank capacity of most Seat Ibiza 1.9 SDi SEs is about 45 litres (according to our database).

What to do about putting Petrol in a Diesel Seat will vary dependent on the amount of Petrol used. So, there are three possible scenarios:

  • FIVE PERCENT: If you put less than 2.25 litres of Petrol in a Diesel Seat Ibiza 1.9 SDi SE then in most cases, if the car's tank is completely filled with the correct fuel before it is started, it will probably be fine.
  • FIVE TO TEN PERCENT: If you've put between 2.25 and 4.5 litres then you should probably give us a call. This is the grey area where sometimes you can get away with just topping it up, and sometimes you can't. Call us and, with a bit more information, we'll be able to give you the best advice on what to do next.
  • If you've put more than 4.5 litres of the wrong fuel in your Seat Ibiza 1.9 SDi SE then you should definitely get it drained. This equates to more than 10% contamination and exceeds any "safe" contamination level.




  • Flush the fuel lines
  • Purge all contaminated fuel from the system
  • Clear the fuel filter and flush it clean
