I parked my F250 Power Stroke as a daily driver whenever diesel hit $3.93 ($100+ fill up), I am working 7 days a week and was filling the truck up 3 1/2 times a week.
Not quite two months ago I purchased this little gas miser... that is saving me $900 a month over driving the truck.
I'm not complaining too terribly much right now but whenever I start filling up the boat that holds 175 gallons of gas that tune might very well change.
