Definition: A six-wheel tank truck, with pump, hose, and
dispenser. Bulk trucks are more than happy to stop and fill
vehicles with LPG carburetion (they will however refuse to fill
domestic gas tanks that use POL fill valves). Simply flag the
truck down and yell "Carburecion" and point towards
your engine. Prices are posted on the side of the truck for
Domestic fuel. "Carburecion" prices are several
centavos per liter higher. You will probably be asked to
follow their truck a short way to a more comfortable site in
which to fill your tank (Many Méxican motorists are
uneasy around propane and frown on highway-side filling).
If you are going to be the area for awhile, save the receipt
from the gas purchase. You can telephone the local office and have
the bulk truck fill your vehicle right at your campsite (I
always wait until I need a minimum of sixty gallons). This can
save considerable driving and headache so I always tip the truck
driver twenty pesos, and offer a cold soda. Another way to do
this is to flag down a bulk truck and tell the driver to meet
you at --- on such-and-such a date and time. Fork over twenty
pesos as a "tip" and you can count on him showing up
(but not necessarily on the exact day or time specified).
Definition: Tankers are eighteen-wheelers (actually
twenty-two wheelers) that supply ten thousand gallons of LPG to
the "Bulk Plants." The trucks have no onboard pump.
They unload cargo via the central pump at each plant.
