I have been following this product for a while. The company claims to have lots of over the road Series 60 big rigs using his system with a routine savings of 15/20% without any other conservation measures, and up to 50% with other driving measures involved.
When Diesel creeps over $5 which might happen this summer a $1.00 a gallon might look like a real savings.
Love to have comments on this. Once you check out the equipment, and if any of you (Jon) feel its worth the investment and won't burn up the engines where would you install all of the needed equipment?
