Should be ok.

This might be one of those times when adding a lubricity enhancer (2SO) or something similar might be a good idea.

Add 1 litre of two stroke oil..... For the sake of a £5, help save your fuel pump and injectors..

(Been there)

The fuel pump is in danger of being severly damaged. In some modern cars even 5% petrol in diesel can wreck pumps.

If you can, syphon as much out as you can store and refill with diesel asap. Use up what you store a gallon at a time.

The two stroke oil might work too. Petrol reduces the lubricity of the diesel, which is critical to lube the pump seals. The petrol also attacks the seals in many vehicles.

If it is a tddi, it uses a relatively low pressure pump which is more tolerent of misfuelling than a high pressure TDCI (common rail) engine. I'm assuming it's the former.
