The price was right once again as I filled up Tuesday at the OnCue Express near the Capitol. My purchase of more than 6 gallons of CNG totaled only $8.85.
There is no way to complain about that, but I was a little puzzled when I started figuring our my gas mileage.
I didn’t write down the exact mileage number when I got a CNG fueling lesson Monday in Kingfisher, but I know about what it was.
I drove about 85 miles after leaving Kingfisher, meaning the 5.749 gallons of gasoline equivalent I bought at Love’s Country Store (for $8.04) got me about 14.8 miles a gallon.
That’s seemed a little low, given that the folks at Carter Chevrolet and OEM Systems in Okarche who loaned me the 2010 Tahoe I’m driving for the next two weeks told me CNG performs about the same as gasoline.
The Tahoe is supposed to get somewhere between 16 and 21 miles a gallon, so I was a little disappointed to get less than that in my first CNG-fueled outing.
It’s still too early to say how CNG stacks up against gasoline, as I’ve got about 10 days of driving left to do before my test is over.
I’ve heard a lot of questions about the cost of CNG vehicles, which is something I’m researching for a story in The Oklahoman on Sunday.
