SPADP fleets are saving around $1.25 per gallon using autogas vs. gasoline, even considering the 90% MPG equivalency between autogas and gasoline! By switching to autogas, the Muscogee County S.O. expects to save about 40,000 in fuel costs annually-for every 30 vehicles they convert! That's before factoring in their lower maintenance costs, since autogas has a higher octane rating and burns cleaner than gasoline. It's also important to note that 98% of the U.S. autogas supply is made in America.
