Narrative:
The aircraft had a #1 generator failure off the gate in iad and I was deferring the #1 generator/CSD per MEL card. I did not realize the MEL card had been revised to require a check of the APU oil and the affected CSD prior to departure and failed to have them checked. The previous MEL required only an oil check of the CSD within 5 hours flight time.
