Whelp, if you keep your car a SBO, or, a SBC, even a buick or poncho v8, clean propane and propane accessories are an option for you courtesy of Hank Hill.Ford sells a lot of trucks to Farmers. If you live a 1/2 to an hour from town, heater blasting in -40 pulling a big trailer, how long will it last? I hope manufacturers push Hydrogen cell as well, if we have to go petroleum free, nice to have options.
Even my 8.1L can go propane courtesy of a Schwan's truck. You know what I don't think can? An LS,swap. Just another reason they suck.
So there's that in your back pocket.
