So glad gas is going down!! It's down to $3.15 this morning and I've got to fill up at lunch.
And yes, always go by what your owner's manual says to use. 91 gas is only for cars that need it (like mine

).
I know people always say that Europe and others are paying more but that's because their demand is not as big as ours in the US. Their cities are smaller and everyone usually walks everywhere. Such is not the life here, I live 26 miles from my job.
