I would only recommend the following.

When the tank down to 1/4 then chuck the whole can in and fill up (it has to go in 1st so when the fuel goes in it will mix).
When I use it I only ever half fill the tank so it pulls through neater (it won't do any harm in my old cars I use to put it neat in the fuel filter).
