How much fuel does a tractor trailer gas tank hold?
Class 8 trucks don't use gas - they use diesel. The capacity of
the fuel tanks depends on how it's ordered. A local truck might
only hold 100 gallons or so, while a long distance line haul truck
might hold well over 300 gallons. For most fleet truck, 240 to 280
gallons is the norm. The truck I'm currently driving (and typing
out this post from the sleeper of) has a capacity of 260
gallons.
