yeah i understand that, but here we don't have to have a special license, as for the road tax, like i said, the places round here that advertise it for road use, are ususally cheaper than "for heat" co-ops.... because one is using it as an alternative fuel... other states are even better about it, like california gives u a break on road tax, and a higher tax return atr the end of the year for using an alternative fuel..... my cousin lives in missouri, and believe me, your DMV laws SUCK, and you would think with all the extra stuff they charge you for you would have better quality roads, but, and i think you will agree with me, you don't....lol
the mileage is obtainable provided you take advantage of the fuels high octane rating, and bump up the compression and advance the timing
