Well - a little update.

I had heard that adding too much TC-W3 causes mileage to drop. I started using 1 oz per 5 gallons, and it worked well. Then I moved to 1 oz per 4.5 gallons and saw a slight improvement (above 1 to 5). Most recently, I was a bit more liberal, approximately 1 to 4 - result, gas mileage for the most recent tank dropped by 0.9 MPG.
