While I didn't have highway numbers prior to install (I don't do much "true" highway driving at all), my combined driving has increased significantly from the 14.5 I was previously getting. Given the average MPG increase and the current cost of fuel being about 4 bucks a gallon, my "break even" point where I'm actually in the green on this purchase should happen in about 8,500 miles... Not bad! I always like ROI's with less than a 9 month payback!!
I was wondering if you could offer some updated fuel efficiency numbers? I've been eyeballing this product for a while and I don't wanna be disappointed 6 months from now. Also, what octane gas have you been using?
