I continue to use TC-W3, and have now settled in on a ratio of 1 oz TC-W3 to each 4.5 gallons of gasoline. I have also recently changed from SuperTech TC-W3 to West Marine Premium TC-W3. Over the past 5.5 weeks, this has consistently netted an an additional 0.3 MPG improvement above my prior baseline (w/ TC-W3). Oddly, the tailpipes on my 2006 G35 6MT have no soot or discoloration whatsoever.
