A "little" more wear? 3000 vs. 0 rpm is a lot more wear. For my hybrid I take off as close to 800 rpm as possible, to minimize clutch wear. The electric motor provides the torque.

My Honda Insight with it 11.5:1 compression ratio does this automatically. All I have to do is run octane 91 gasoline (which would be considered 'standard' in Europe).

Many modern cars do the same thing. I just saw an interview with a Ford engineer where he says their engines detect higher octane mixes & advance the timing to increase MPG.

The new 13:1 Mazda engine runs okay on subpar 87 but advances the timing on 91 octane. (In Europe Mazda increases to 14:1 ratio, and recommends 95 octane.)
