Side effect of overheating

My V6 Sonata is used primarily for city driving. I have been told
that this driving pattern can somtimes result in a deposit build-up
internally on the engine.

Recently my car overheated because of the failure of the water pump.
The water pump was replaced and now the car runs as good as ever and
the bonus is that my MPG creeped up just a bit. Can this be the
result of deposit build-ups burning off when it overheated?

I check my MPG closely by setting the trip meter to zero when I fill
up and then on the next fill-up I divide the miles driven by the
gallons needed to refill. I do this check frequently.

Remembering when with carbureted cars I sometimes sprayed a bit of
water into the intake to clean out deposits.

From another old timer. In the 60,s in Australia a lot of the cars being
raced had water injection
where water was bled into inlet manifold. You could even buy kits to fit to
your daily driver. Suction
from inlet manifold just socked a tiny amount of water from a tank in engine
bay. Cars apparently (allegedly)
ran smoother, cooler, better mpg.

It's probably just a coincidence. Perhaps you're driving a bit more
gingerly since you had the overheating problem?

true, and the water spray in the engine is similar to the reason that
automobile engines seem to run better in the rain....you're sucking in moist
air.
