Translation of lubrificar

for a minute I blamed the burger that I had eaten at the duty free back in Cancun, but thinking a little further I recalled eating street food the night earlier, as it was Mexican independence day.
I even put on my Poncho, a plastic rain coat, in order to protect myself from the aircon-breeze. Somehow I managed to fall asleep and woke up at around six in the morning when we approach Palenque.
I visited the Hurricane watch center's website on a hourly basis hoping it would just go away, bt hurricane Ivan was on a direct path to Havana. It did not stop my vacation plans and I left the office.
