Let's do the math Posted by tibbidoh [Email] In Reply to: Re: i'll be the lab rat for those plugs, Paul Clifton, Tue, 29 Jan 2008 10:54:01 Members see ZERO ads on the bulletin boards and get more feature. - Help Keep This Site Online - Signup |
Went to the site and it said that the plugs would pay for themselves in a year and then you would reap the $'s in saving there after. So assume that you are getting an average of 25 mpg's and gas is 3.00 $/gal. and you travel 10,000 mi/yr so you yield a annual fuel cost of $1,200. Plugs $100.00, annual fuel cost reduced to $1,100 and you mpg's have to increase to a little over 27. Sounds bold to me (and of course they don't include the finance cost of $100.00 amortized over a year) 2 more cents to consider. :^).
