Narrative:

I was servicing all 3 engines and svced #1 last as it was the last one shut down. I was thinking about returning the oxygen cart that was needed for servicing the aircraft. Because I was distraction by that thought, I forgot to secure the oil cap because the door on the cowl was down. I thought I had capped the tank and secured the door. 6 mins later, the next aircraft came in to gate. Approximately 15 mins later, I went to service all engines on that aircraft. I then saw the oil cap and contacted lead who contacted maintenance control.
