No. The track inserts and load wheels are manufactured with lubrication already in them, which helps them roll in a smooth motion. Adding any sort of additional lubrication could cause the load wheels not to spin properly and could cause the drive arms to slip when pedaling. Adding lubricants will also cause more dust and dirt to be collected, which could lead to accelerated wearing of the track inserts and/or load wheels. Wiping down the tracks and load wheels with a slightly damp cloth before or after every ride to remove any debris is the best way to keep the tracks and wheels running smoothly.
