Oil use, blue exhaust smoke, an engine knock or low compression can mean worn pistons, but rings, valve seals and cylinder wear produce similar symptoms, so pin down the cause before you order pistons. A first check is measuring the cylinder bore with the engine off and cool and comparing it with this piston's 102.0 mm bore diameter; a shop can run compression and leak-down tests.
