Narrative:

Received aircraft from maintenance. Fuel quantity showed left 5900 pounds, right 2700 pounds. Fueled normally. On liftoff aircraft rolled right requiring 3 1/2 units of left aileron trim to maintain wings level after 40 mins flight time. Approaching toledo, I received a fuel asymmetry alert and now left tank indicated 3200 pounds, right 6400 pounds. After landing used under wing fuel sticks to confirm gauge readings now correct. Refueled to balance tanks at 6400. Confirmed with sticks. For remainder of day problem did not recur. My concern is that I departed with 3000 pounds less fuel than I thought. In the future when ever a discrepancy shows between fuel quantity gauges I will stick tanks to double check. This did not enter my mind because the aircraft had been in maintenance for 2 days, I felt perhaps some of their work had caused the out of balance indicated before fueling.
