Good points by Darin (metrompg) and Andrew (pale). I agree. Best cruise mpg is during lowest cruise speed in your highest gear.

I just had the "opportunity" to lug my engine due to a clutch problem, and retract my original impression. It is, indeed, possible to damage your engine by lugging it too low in rpm at too low a speed. I had mine shuddering due to starting without a clutch in 4th gear. It's possible, and you should avoid it.
