I need your help/advice,
I went to Halfords yesterday to buy some Injector cleaner, got a guy to show me where it was and he made sure i found the exact product that i wanted. I paid and ready the instruction leaflet in the car park and then went straight to the petrol station, The petrol station was busy but i double checked the leaflet and it said to add a full bottle to a tank of fuel.
It seemed to take an age to empty into the tank (put about 350 ml of the 500ml bottle) before i filled up the tank (48 litres worth).
Whilst driving home i realised that the bottle had a different picture on it to the box it came in so i pulled over to take a look and my heart sank. I had done about 10 miles since leaving the petrol station to realise that the bottle in the box had been swapped for some engine treatment Wynns.

I pulled in at the next petrol station to see if i could squeeze in more fuel (brim it) to see if the oil additive would sit on top of the fuel to enable me to drain it out… no luck.
Do i get the tank drained and rule lines flushed?
Will topping the fuel tank up from 3/4 to full for the next month help to dilute the additive and all be ok?
What should i do interim of dealing with Halfords?
Any help will be much appreciated.
Currently the car is at home not been used.
Thanks
