Ok, since i've had my Rubi I've been logging the mileage and it was a steady 13.1mpg 95% city commuting to work. I was getting about 240 miles per tank if I ran it to the bottom end of the red zone. After a nice trip to Drummond island I have only since been able to stuff 14.9 gallons into this supposedly 19 gallon tank even if I run it as low as I dare shy of dry. And after a full fillup the gauge doesn't even make it to full. Think the tank has a dent or two? Anyway, my range is now down to about 210 per tank. In that time I have installed a TB spacer in the hopes that I get better mileage. For the last 4 tanks since it was installed I have averaged 14.8mpg. Same commute, same driving style. Was it worth $70? To me, yeah, but YMMV :lol: Now I just need to get that darn dent out of my gastank.
