    Has anybody out there tried Prolong. I know some swear byit. And I know others that say it is snake oil. Has anybody actuall tried it. It claims to increase Fuel economy as well.

    Paging Tom. Tom are you there?

    I'll go ahead and call snake oil. Tom should be by shortly. ;)

    http://www.x1r.com/ used to work WONDERS in my 1999 Kia Sephia. Around 8MPG extra, shown best when I flushed my engine and then had to retreat it to get back the missing MPGs.

    I never saw any real value in the X-1R I added to my Prius, so I stopped buying it. Better designed engine, I guess...
