Message	Is it indeed a "cumulative" effect of the damaging harmonics or not? And do those damaging harmonics only occur beyond a certain horsepower/ rpm level, or are they always present, insidiously doing small bits of damage? I would rather spend a bit more to keep my engine together, than rebuild it again down the road. Maybe Nissan put that paperweight on the end of the crank for this very reason...?
