I have talked to three different gasoline distributors in Oregon so far and they are all telling me the same thing. By 16 September 2008, when the whole state is supposed to be E10, there will be no 91 premium unleaded gasoline available in the state for those SB 1079 users who need premium unleaded. The terminals will only be ordering and receiving "suboctane" blending stock for E10 which is about 88 AKI for premium unleaded 91.
I am working with some pilots in AZ on ethanol problems and they found out today that they have the same problem already, all suboctane blending product, and they don't even have a mandatory E10 law. They can't even order premium unleaded.
As a state goes ethanol in all of their gasoline, whether they have a mandatory E10 law or not, the terminals order suboctane blending product because the ethanol will bring the AKI up, about 3 points for E10 and it is cheaper (but do they pass along the savings?). Once that happens there is no premium unleaded anywhere for Petersen STCs or Rotax 912s (100 HP).
This is spreading rapidly. I will be talking to an Idaho Aviation Association board member about this tomorrow ... he is concerned. Idaho has no mandatory ethanol law but pilots are reporting that it is getting difficult to find unblended fuel.
