As long as the throttle plate is closed (carbureted engine), the airflow through a spark ignition engine is at a minimum and so the fuel flow is at a minimum, since the engine runs at a near constant fuel air ratio. There is a bit more air going through the idle air port in low gear (high rpms) than in high gear (low rpms) because the pressure differential across the throttle plate(and idle port) are greater so a bit more air is going through the carb. I seriously doubt you'll notice the difference in fuel milage.

If you want to really save fuel, drive like you have an egg between your foot and the gas pedal. No jackrabbit starts as the stop light turns green, and don't accelerate quickly in other non-emergency situations. Cruise your VW around 55 mph.
