Once he gets the mechanism to take the gas from his wells on his property and put it in his tank, cost goes to .30 cents a gallon. He did the conversion for $3000.
Am I missing something here or are we being completely SCREWED by our own ignorance, the government, and big Oil?
I couldn't make this up, I've seen the rig and the receipts myself, he's my hunting buddy.

CNG usually takes a very heavy walled tank to hold the CNG. When I was in Shanghai a Buick Century was a cab that picked me up running on CNG, but the trunk was all tank and no room for luggage. Mostly a trade off somewhere down the line for alternate fuels. Diesel is the most viable albeit more expensive than E-10 87 octane, but cars using it can get better MPG. My 78 Rabbit Diesel averaged 49 mpg for the 6 years I had the car with a top mpg of 60 mpg. Upstate NY winters (that seemed to last 5 months) would drop miles down to 41 mpg

Latest MPG numbers...getting better and better as the weather warms:
623.4 mi, 13.968 gal. ==> 44.63 mpg.

I fully expect to pass 45 mpg by the end of summer.

For those interested, you can track my progress here:

For the skeptics, I believe its possible to get this kind of mileage with the right driving technique and conditions. I recently got 35 on a trip, at 60 mph with 3 adults and the back filled to the top with luggage. I didn't even try very hard to get it. However, 5speed4 has some pretty unique circumstances that most of us will never have. In real world day to day driving you will never see 40 mph.

Agreed. My commute is about as ideal as one could hope to get on public roads. I do think that 35 mpg is not out of the realm of possibility on most people's commute (assuming mostly highway), particularly for the guys with 2009-2011 models with the 2.2L (smaller engine, direct-injected, and taller gears than my '06 2LT).
