Comment was made early in this thread about the replacement of Shell Optimax with a fuel that contains ethanol.
Optimax was replaced by "V-Power" 98 octane. There is no mention on the pump, or on Shell's website, of there being any ethanol in V-Power. At the same time, a new fuel "V-Power Racing" was introduced. This is 100 octane with 5% ethanol, this is mentioned both at the pump and on the Shell website. According to the blurb V-Power is "friction modified" and cleans up gunk in the engine components better than Optimax did. Make of this what you will. But it seems there is no ethanol in the direct Optimax replacement, only in the new 100 octane fuel.

Did you figure out how much diesel you have to burn to make a liter of ethanol? In fact for energy balance you need about 1.5 liters of ethanol or so to equal a liter of diesel. The very best I've seen is around a 20% energy gain but that's in good soil with lots of water and where you don't transport the crops or the finished ethanol very far. In Aus, likely negative but ethanol is a nice political "faux fuel" that pollies can use to pay off the farming lobby and other rent seekers while claiming to reduce dependence on foreign oil..
