Thanks for the suggestion. I
am looking at something similar...
Actually planning water/meth injection for economy reasons. 'Pane injection, IMHO, is simply swapping one fuel for the other, which under current pricing is virtually identical in price unless you buy in bulk (which I can't/won't do). It is a good idea, though. One guy I know of is getting about 67 mpg diesel when using 'pane... but he's burning 4 gallons of 'pane for every gallon of diesel.
Water/meth is simple windshield washer fluid, and one gallon will last 2-3 tanks of fuel (or so I've been told), and costs between $.90 - $1.65. The water/meth system runs about $420.
