With a lightweight (single mass) flywheel, and no other harmonic dampeners, it won't "wear out", but you run a substantial risk of the crank cracking (they are cast) from excessive torsional harmonic stresses (regardless of annual mileage) that are normally absorbed by the dual mass flywheel............seen it more than once. If you want to run a lightweight, single mass flywheel, you should fully harmonically balance your rotating assembly with the LW flywheel indexed to it………
