Exactly what I was waiting for. I filled up today (7 gal) @ $2.69/gal, compared to unleaded gas currently at $3.20/gal. Gas is unusually high in CA currently due to a refinery fire, labor slow-down, and limited market because special mixtures are mandated. A Propel station is 4 miles from my house. Cheap, renewable source, more power, smoother, less emissions. What's not to like, other than lubricity meets the bare minimum. I am not enamored with diesels and have just kept mine thru high fuel prices just in the hope of future cheap bio fuels, which may have arrived, at least for us in Sacramento and East Bay. I expect Propel will expand if the public likes it.
