Pretty much every state that has mandated oxengenated fuel is using 10%
ethanol. It replaces the MTBE (or is it MBTE...) as the oxegenator. For us
in the northeast, it's been required since the early 90's.
Answering the initial question: the 10% ethanol fuel works fine. Note that
these motors are not high tech in any way and a stock late TR6 with 7.75:1
compression motor would have absolutely no problem with the fuel. The
thing to watch for is that if your fuel tank has water in it, the Ethanol
might not mix properly and you might see fuel related problems, but the
fix is easy - purge the fuel system and then just use the newer fuel. If
you've joined the ranks of increased compression and all that stuff, the
proper octane should be used. Also note that Ethanol has less BTU's per
unit, so your fuel mileage will go down a tad because of the fuel mix.
