don't feel too bad. here in mex, i am afraid to use the regular! the fuel is so bad here, we have to change fuel filters at every other oil change! i do feel a little satisfaction (at your expense), since 2006 is the first year in the last 8 that fuel is more expensive in the US than here.
thank God the H3's have small fuel tanks! my bronco has an oversized tank and costs about 85-90 dollars to fill, so at least when i fill up the hummer for around 50, it feels like i am getting a good deal!
don't worry, fuel will continue to go nowhere but up!!!!
