Myth #2: The return on investment for natural gas trucks is too long.

Model 384 LNGFact: Natural gas costs roughly 30 percent less than diesel when comparing diesel equivalent gallons (volumes of fuel that store the same energy), but the LNG truck itself can cost 25 percent or more than its diesel counterpart, largely because of the onboard cryogenic fuel tanks. Calculated savings over a truck’s life will depend on the number of miles traveled. Some fleets report ROI on the added cost of the tractor at only 12 months for a truck traveling 120,000 miles annually and saving $1.50 per gallon, while other fleets report ROI of five years or more.
