Xtreme Used Cell Phones

Why doesn't anyone use this for their car and does this work for my boat?

recently got a fuel additive called syntek Xtreme fuel treatment.. i learned of it on here and have had wonderful success.... My car gained a extra 4 mpg and im saving about $150 in gas a month ( its helped me get dish television and a new cell phone) how come no one has heard of it and im wondering if it will help my boat out as much as my car .. the fuel is different and the engines are different .. anyone tried this out yet?????????

Yea use it for any engine !!!! i have a small lawn company on the side and it saves me soo much gas during the summer.. and im saving a extra 90 miles a fill up.. I don't get how people wouldn't put this in any engine they have.. it cost maybe $3.50 and im getting soo much more out of my engines.. I recommend this to anyone and everyone..
