Compatible with any shredder, this oil lubricates the cutters to ensure best shredding performance. GBC oil is a synthetic blend that will not cause buildup on shredder parts. By reducing torque and allowing cutters to move freely, the oil helps to reduce the risk of paper jams. For high-level performance with a GBC SelfOil shredder, simply pour the oil into the shredder's designated oil reservoir. To use with standard shredders, pour a few streaks of oil on a sheet of paper and run it through the shredder.
