The highest profit margins for all rental car companies are fuel and insurance.
Which is exactly why they push these items so hard, especially on the obviously infrequent renter (who, in most cases I witness, usually bites, especially on the insurance).
Although Hertz doesn't do it a lot, rental companies also make a killing on "on the spot" upgrades to a "much nicer" car for "only" an extra $10 a day.
