Sorry dude, but your wrong. The lug that you feel on the engine isn't because there is more load on the engine. It's because the RPMs are way way down and the motor isn't making as much torque at 1100 rpm (approximately 55 in sixth for my car) versus 2000 rpm (80 mph my car). Also take into consisderation that as speeds increase the force of wind resistance increases exponentialy. My car gets ~23 mpg average going from SD to Phoenix when I keep it at or above 90 mph. It averages about 28 if I keep it around 75 mph.
