Using the fan, heater

If it does use extra fuel to run the heater, not enough to worry about. If they tell you that it'll put more load on the charging system and that'll somehow cause you to burn extra fuel...then ...don't run your headlights or wipers, they'll give a big hit to the MPG

Headlights and wipers are not optional. Using the heating system often is.

Yes. Energy is not free. Anything at all in or on the car that requires electricity gets it from the alternator, or from the battery which is replenished by the alternator. Any load whatsoever on the alternator is in turn a load on the engine.

Is it a huge hit? No. But it is a hit.

It's a load on the electrical system. The serpentine belt, rotating mass, etc are a load on the engine...using the turn signals isn't a hit on fuel economy. Besides, I never use the wipers...I just "plan ahead" and avoid those rain clouds.

You're being facetious... Right?

It's a bailout joke around here, based on his theory about dodging. If he can avoid accidents by dodging deer that spring onto the road by planning ahead for it, I can dodge the raindrops.
