What about propane? Isn’t it more expensive? The reason I ask is there are still many, many more places to get propane than compressed natural gas at this time.
However, most retail propane outlets are not simply drive and fill up. At my local propane place, I have to see a guy who looks very much like Hank Hill, and it takes him at least 15-20 minutes to get around to filling my tank. Nice guy but always busy.
I can’t imagine the process for self-service for propane. They act like I’m going to blow myself up just carrying the tank back to my car.
Before you say you can do the same with gasoline, let me state that I can ignite/explode a bottle of compressed gas easier and from farther away than what I could do to/with a tank of gasoline.
I know the Ford 150 package preps for both CNG or Propane.
Propane does tend to be more expensive than CNG but in most location less expensive than gasoline on a per energy basis.
