magnets on fuel line

i recently added a magnetic system to my 1990 (approaching 199K this
week) in an attempt to improve mileage. (the basic premise is that if
you magnetize the fuel positively and the air negatively (or vice
versa), they'll remain combined after compression in the chamber
resulting in a more efficient burn.

has anyone else had any experience with this?

after about six weeks, i've gone from about 26 mpg to about 30 mpg
(all city). at $3.20 a gallon nowadays, that makes me pretty happy.
the thing is, the car now overheats anytime i sustain anything above
4000 RPM (or about 80mph) for 2-3 minutes. (i live in LA and the 210
seems to average about 80 in the middle lane when i'm on the road).
generally cranking on the heat full blast gets the needle back to
center, but the dash still feels *really* hot, and everything under
the hood is still *extremely* hot when i've arrived & looked under the
hood.

while i suspect that the hotter burn is the primary factor (the
accompanying literature suggests that 87 would burn like 100 with the
magnets), i should mention that i recently replaced the front license
plate - have driven without it for eight years, finally got a
(parking!) ticket, and the outside temperature has been in the 90's &
100's most of the time - which i though might be a factor, but i've
seen the temperature come back down to normal while at a dead
standstill while cranking on the heat full blast.

so i guess my main purpose for posting is to solicit comments about:
- magnetizing the fuel/air to improve mileage & performance;
- the impact of running the equivalent of 100 octane (i have noticed a
little more HP on acceleration and i still am usually still in 3rd
gear when pulling on the highway at 65mph) in a 16 year old car - is
it within the recommended tolerances?
- should i go ahead and maybe replace the thermostat anyway? (i *do*
plan on flushing the radiator);

thanks.
