I think there's a huge market where I am for a lawn company running on greener or alternative fuels. Think I could sign up a lot of people taking care of their own yards if they thought I could do it "greener." And they'd probably be willing to pay a premium for said "greener" service. So is there anything else I can run regular gas mowers on? Was introduced to this stuff: http://www.aspen.dk/Aspen_(eng)_Consumer_Products_Petrol_DXNI-3328_.aspx But don't have any idea what it costs or if it's even locally available. Not willing to exchange all my equipment for diesels or whatever, but if I could run different fuel and advertise as such with my present equipment without going broke doing it I could maybe get a lot more customers. This is a liberal hippie town. Any suggestions?
