[LINK] Fuel consumption

This is off-topic for Link, but, am wondering if the physics/engineering 
(whatever) people here can suggest how to resolve something I've been 
wondering, besides doing road tests.

If a vehicle has an overdrive gear that kicks in at 80 klm/hour, would it 
be better for fuel consumption to drive at 75 klm/h and higher revs, or 
faster at 85 klm/h but with lower revs?

Cheers,
Stephen.
