Narrative:

On early morning of mar/xa/01, I was assigned an overnight check on a DC9. At about XA00 the WX was around -10 degrees wind chill and snow was heavy. I was having problems servicing the engine oil with an oil service cart. I needed 4-5 quarts per engine and after about 200 pumps I still didn't have 1 engine svced so I grabbed a golf cart and got 6 1-QUART cans. Returned and finished servicing 1 engine and went to #2 engine open service panel and removed cap. Placed cap on cart. Svced oil and closed panel. Flew from ZZZ to xyz. Pilot wrote up #2 oil being low by 10 quarts (it holds 16 quarts). Contract maintenance in xyz reported cap missing. They replaced cap and svced oil and sent it to ZZZ. I was informed by the lead who had that airplane the next night. I went to the golf cart I had the night before and found the oil cap. I feel that the WX and the head cold I had at the time were the biggest causes. It was an accident I regret and am very glad nobody was hurt. I have been working line maintenance for 15 ys and this was the first time it's happened to me.
