Put Diesel in a Petrol Honda Civic 1.5 LSi?

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

The first thing we need to look at is the Honda's fuel tank capacity. So, what is the fuel capacity of a 1.5-litre Petrol Civic 1.5 LSi? The answer is: the fuel tank capacity of most Honda Civic 1.5 LSis is about 45 litres (according to our database).

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

(Please Note: These figures are approximates. Running an engine on any amount of incorrect fuel can cause damage, regardless of contamination percentage. Information given here is advice based solely on our customer reports and case histories. Full details should be procured from your vehicle manufacturer.)
  • FIVE PERCENT: If you put less than 2.25 litres of Diesel in a Petrol Honda Civic 1.5 LSi 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 Honda Civic 1.5 LSi then you should definitely get it drained. This equates to more than 10% contamination and exceeds any "safe" contamination level.
