Translation of lubricar

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.
The vehicle turned west towards the countryside and drove on Route MEX186 towards Escargera and then southwards. I fell asleep soon and had a very bad sleep, as it was colder than I had imagined.
The days before I left to Mexico and Cuba I started to track the hurricanes in the region. September was not the ideal time to visit the region, but it fitted the best according to my previous boss.
