Vote on how you broke your engine in, and if it consumes oil.
Easy - Light throttle, low revs, efficient driving. Little to no engine braking. Possibly some cruise control.
Recommended - What the manual recommends. No cruise control or racing, varying loads and speeds under 4K RPM.
Hard - Heavy throttle, high revs, sometimes exceeding 4K RPM. Lots of engine braking, shifting often and to lower gears than necessary.
