With the wild fluctuations in gasoline prices a lot of people are looking at switching to compressed natural gas. While it costs thousands of dollars for the conversion, the work will pay for itself over time.
The price runs from about 10-grand for a full sized truck, to about $6500 for a mid-sized car. But that cost is offset, by a 50% state income tax credit. Deciding if it will pay off you, has a lot to do with how many miles you drive.
Tony Griffith of Tulsa's CNG2GO says for an average person that could talk four or five years. But if you commute a long way every day it could pay for itself in as little as a year. Driving a 100-miles a day is a good rule of thumb, for a quick payoff.
The whole process works because the efficiency of natural gas is the same as gasoline. It's just a whole lot cheaper. It now runs anywhere from $1.25 to $1.75.
But you can purchase a home compressor and fill your tank directly from your home's natural gas line at a much lower price. While there are now about a dozen stations all over this metro area, a long trip may take some planning.
Fortunately there's a phone application that will show you all the stations in the country. Converting to CNG takes two or three days but Eddie Craig of CNG2GO says don't try to do it yourself.
Dealing with 2000 pounds per square inch of pressure is dangerous and the work should be done by a state certified technician.
In contrast, CNG tanks have been show to be very safe on the road.
When the work is done you have a car that still burn gasoline, and the fuels can be switch on the move.
