Gasoline:

All gasoline is distributed by the national oil company Petroleos Mexicanos, known as PEMEX. These ubiquitous green and white gas stations are abundant in the cities and towns of the Yucatan, but if your destination is a distant jungle ruin or a long drive on the Gulf coast, start with a full tank. In Pemex's stations are full service. At your request, the attendant will fill the tank with "magna" or "Premium". He will wash the windshields and check the oil. After receiving service, it is customary to tip the attendant with five or six pesos. You can also buy snacks and visit the sanitario or restroom.

Green Angels:
Mexico has a wonderful roadside assistance service called Angeles Verde or the Green Angels. These are auto mechanics in green utility trucks who patrol the major roads. They can provide gas, oil, tire repair and other minor maintenance, as well as arrange towing. They only charge for parts. Their labor is free and they don't accept tips. They are currently celebrating 32 years of service.

DISTANCES:

The Yucatan, and all of Mexico, uses the metric system. All distances are given in kilometers. To convert kilometers to miles, multiply by 0.62.

Distances from Merida in Miles:

Toll Roads:
Highway 18 from Merida becomes the 180 toll road, also called a cuota or carretera de cobro, going east to Cancun and south-west toward Campeche. This four-lane speedway is by far the fastest route from one end of the peninsula to the other. Using it, you can avoid 83 topes and 43 villiages. Along the way, you will encounter toll booths or casetas de cobro. Expect to pay $24 USD between Merida and Cancun. Have pesos in hand because the exchange rates at the toll booths are less than generous

Bus Services:

Merida has a wonderful bus system. Most buses are clean, modern and well-maintained. Some first class busses are air-conditioned, have bathrooms and even a snack bar. In some towns, you can also take a combi, a car or van maintained and dispatched by a collective. Using the bus system, you can travel anywhere you might want to go.
