Narrative:

On IFR flight plan flying in the clear on V25, I inadvertently drifted off the airways centerline. ZOA advised that I was about 3 mi west of the airway centerline. I corrected immediately. No other aircraft were involved. Closer attention to my navigation would have prevented this occurrence.
