What I look for locally is called 'clear premium'. I have used it in my 1971 Superbeetle to protect the fuel system, but there is a member here (funkhoss) who uses it in his Geo Metro and gets 87 MPG; so now I'm using it (first tank) in my 1990 XFi.
The increased price
versus increased mileage suggests total cost involved
versus bragging rights.
