I think it may be less than 1% right now, so Magic Spark Plugs won't make much difference on their own.

Depends on how you define it, my 2.2 motor in certain lighter older rigs got 32mpg, my XFE gets 37mpg+

I think thermodynamic efficiency comparisons would tell how much fuel is really wasted.

If the same motor using different timing and motor controls using very similar gearing gets significantly better FE fuel must have been wasted on the previous motor? (even if it was burned somewhere)
