OH BTW, i forgot to mention I stole the plans to build the system off the internet (the same ones they charge $100 for). The i went to Home Depot and built my own system.

So if this system does turn out to be a scam, the only people to profit from me is my local Home Depot.

*SVOboy, yes i understand to conduct a proper scientific experiment there must be extensive amounts of control with as little variables as possible. I dont' have a science lab, but I assure you, I am trying to keep as much control as possible (ie, filling up at the same gas station using the same pump every time, filling up at approximately the same ambient temperature, installed a vacuum gauge to try to keep my driving style consistent, I'm a delivery driver so most of my mileage is all highway).

Here is a quick rundown of my results:
1st tank: 54*F, "passive system" = 313.6m on 10.0g = 31.36mpg
2nd tank: 57*F, "passive system" = 330.9m on 10.14g = 32.63mpg
3rd tank: 56*F, "passive system" = 309.3m on 9.79g = 31.59mpg
4th tank: 56*F, ALL STOCK = 281.5m on 8.97g = 31.38mpg
5th tank: 68*F, ALL STOCK = 328.0m on 10.36g = 31.66mpg
6th tank: 71*F, ALL STOCK = 241.6m on 8.08g = 29.90mpg
7th tank: 60*F, "Active system" = 312.2m on 9.85g = 31.69mpg
8th tank: 58*F, "Active system" = 111.9m on 4.02g = 27.83mpg

(*I know these results don't seem all that impressive, but please see my fuel log for more detailed information)
