6%...whoa!
Let me try some math...
At 60 mpg that would give me 3.6 extra mpg. On a 10 gallon fill that would be an extra 36 miles per tank or roughly $1.25 saved each fill up (at current gas prices). To break even on $70 discs I would need to fill up 55 times (that's about 2.5 years of fillups for me to break even...probably 3 years knowing that 60 mpg is not realistic in the winter...hmmmm). They look cool...but 3 years is a long time to break even...no?
I wanted to pour my first couple months savings on gas (switching from 4runner to Prius) on a mod of equal value...tempting.
Maybe time for a poll?
