Tom,
CNG is still a gas vapor, as opposed to LNG, which would be Liquified Nat. Gas. How are they selling a vapor in gallons? No stores around here that I've found,
so I can't go check into it.  What's the refilling like?
Do they provide the tanks and conversion kits? I'd still have plenty of power since my 3/4ton has a 8.1 liter gasser. My other is a diesel, so it wouldn't work.

My truck is one of many white Ford F-150 that are on the road with the CNG sticker on the back. They stem from a law (now defunct) requiring government fleets to have twenty percent of the their vehicles use a "green" fuel. Most used either propane or CNG (compressed natural gas). All of them started life as conventional gasoline engines that were prepped for CNG conversion, and they will run on either gasoline or CNG. The law lapsed, and as the trucks aged they were sold from the fleets.

The truck has more power when running on gasoline and better mpg. I get 18 mpg on the freeway with gasoline, only 14 to 15 with natural gas. I don't know what my city mileage would be with gasoline since I have never tried it, but with natural gas, it is pretty dismal... around 11 mpg. But with gas costing over $3.00 a gallon, and CNG at 93 cents a gallon, it is like driving a 8-cylinder truck getting 33 mpg!

There are several downsides to owning CNG. As Don pointed out, it is hard to pack much natural gas in the tank. Mine is 13 gallons, but I have never been able to fill it with more than 9. How much you can actually put in a tank depends entirely on the current pressure of the refilling station . Sometimes the pressure has been so low that I could only get five gallons into an empty 13 gallon tank! Not only that, CNG stations are few and far between. There are only three between Ogden and Salt Lake City, (but one of them I go past every day on my way to work).

The cost of natural gas varies widely from state to state. In Utah, all of the CNG stations are run buy Questar, our natural gas provider. They are located at regular gas stations, but I pay by credit card directly to Questar.

I bought the truck primarily for fishing. I can get to all of my most frequented reservoirs using natural gas, and it pulls my boat FAR better than my old 4 cylinder Toyota Tacoma!

Interesting to look at the prices of CNG across the country. ALL of the Utah stations are 93「/gallon.
All of the Indiana stations are $1.73 (and few and far between).

California stations ranged from $1.09 San Jose Unified School District - a flet operation) to $4.25 per gallon (Napa - Redwood Chevron).
