Got to thinking about oil, gas, diesel, etc. regarding current prices and the outlook of many about the future of energy. I really haven't read or seen what will become of tools running on oil based products-tractors, lawn mowers, weed eaters, chainsaws, etc.. Will all of our small machines become obsolete without access to the fuels? Will all the smaller engines be able to be converted to burn the "new" fuel? What about those that have purchased these items for the long haul? Will they have to be scrapped? Love my tractor and other "toys" and worry about the future of them.
