Subject: Re: When to change a fuel filter

The Owners Manual and Shop Manual do indeed show a fuel filter change interval
of 60,000 miles.

If I lived in Arizona or Florida I'd change it every 30,000.  I don't think the
gasoline is as clean as Mazda thinks.

I live in Colorado.  I change my fuel filter every summer, approximately 15,000
miles.  The concern here is frozen water where the filter is supposed to be.
You used to be able to toss a bottle of Heet in once a month, but now there is
already so much stuff in the gas that is not gas.  I am afraid to put more
anhydrous alcohol in there.

If you have ever had to lie under a car at the side of the highway when it is
-20 F and change a filter while gasoline trickles into your armpit, even the
Miata filter looks cheap every summer.
