Getting rid of leaded fuels isnt a bad thing... as the formulation of mixed fuels have come a long way in the past 10 or so years. Unless you are running 25+ pounds of boost... you actual motor octane numbers dont require lead and the other reasons for a leaded additive are falling to the wayside as well.

Just for fun i checked VP Trick and Torco Fuels
VP leaded 38 different fuels
unleaded 16
Trick leaded 2
un 1
Torco Leaded 12
un 2
So I would say that the majority of professional motorsports are not using unleaded, and really the "Professionals" make up such a small % of the racing population any way,
I don't know for sure but I would BET 0 Prostock teams use unleaded
I also don't think that the fuel companies push or educate customers on unleaded........ apparently it is more costly to produce and if the US isn't banning it then why would the fuel makers care???
