You are smart not to.It is somewhat labor intensive all that filtering and dewatering, Storage concerns are to be considered. cold weather concerns as
well. after the cost of the kit (frybrid) I figure you need to drive 12k just to get a return on your investment,Now with diesel prices flirting at 3 bucks a gallon
that milage will be closer to 20k before the rig is paid for.
So in my case it would be almost a year before i see a return on my investment.Then and only then could i say i would be driving for free .
or close to it.
