What octane booster
 

Obviously running an import I need to use octane booster. What are you all using? NF sounds the best, who sells in down our way. How much do you use, and how many fills per tank full? what other stuff is about that wont cost the earth to run on.

If you can't get NF, use millers, that will do the job, its what I have used for the past two years with no problems.
