Wonder how their mileage compares with regular gas cars?
Back in the 80's the fleet I worked for had all their pick ups converted to cng. (compressed natural gas). The mileage wasn't easy to compare due to gallons vs btu's but the trucks didn't seem to go as far on a tank full of cng as they would a tank full of gasoline. But then again tank size makes a difference. Horse power was compromised a bit too.
