My work truck is dual fuel CNG. Ill check the mileage I get when I leave OKC tonight. On 16gge I can drive from Woodward to Alva idle for about 13 hours and get almost back to Woodward before I have to switch over to gasoline. I only notice power loss when fighting a strong head wind. The truck is a 2011 Chevy 2500 4x4 crew cab with a service bed on it. I was thinking the places around OKC that do conversions are in the 6 to 8k range. I think Oklahoma still has a tax credit on conversions

We had an '08 Civic GX (which is a dedicated CNG car from the factory) that was my FIL's and holy carp did I love it. At the private pumps we'd pay about $1.50 p/gge, but at the ONG pump (where there was little or no profit on top of their costs, as I understand it) it could get down as low as 0.70¢ p/gge. I think the tank only held 8 gge, so filling up was often only around $6.00 for a good 220 miles of usable range. We also had the slow-fill hookup in the garage that gave it a more complete fill, albeit overnight.

Man I miss that car.

Here, but occasionally There.
CNG may be different from LP, but back when I lived on the farm, we had our trucks and pickups converted to run on LP. The farm trucks had dedicated carbs so they ran on LP only. My FIL had his pickup set up that way as well. I insisted on having dual fuel because I knew that the LP was hard on the valves of the engines. With the dual fuel pickup, I had to make it a point to occasionally drive for 50 to 100 miles on regular gasoline or the seals in the carb would dry out from running on LP vapor.

I can't remember how many times I had to go back to the house, hook onto the trailer with the 500 gallon LP tank attached, and tow that to where my FIL was because he wasn't watching his gauge.

Even now with "flex fuel" vehicles, I learned something. My F150 is like that and the owner's manual states to be sure and drive the truck on non-ethanol fuel every so often. So, apparently the ethanol is not necessarily good for the engines either.

I drive in too many rural areas to ever consider a CNG vehicle. And for daily commutes, we only drive 3 miles one way anyway.

LPG (Liquified petroleum gas) is basically propane. CNG is natural gas. I used to know more about this stuff, but if I remember correctly, one required more modifications (and that might be LPG). Not sure though. Someone here will know better on the subject than me.

I have been researching CNG a bit. There are a ton of filling stations around OKC. I drive a Tundra 5.7 about 25,000 miles a year. At $3.65 v $1.35 and 15mpg it would take me about 3 years to break even. Joe Cooper in MWC is selling F250s with a conversion that will not void the factory warranty. They haven't sourced a conversion for the F150 yet but I'll probably be in line when they do.

BAF is the outfit that does them for ford and ford keeps the warranty, cng ready trucks have a hardened valves .

There are several companies in Oklahoma that are approved vehicle modifiers for GM, Ford, and Dodge. OEM Systems in Okarche is probably the largest in the state. Not sure where you got the hardened valves info, unless your talking about factory installed systems, but outside of an intake swap nothing else is done to the motor during a conversion kit install.

Right now in Oklahoma and you get a tax credit for 50% of the conversion kit until 2015. Also you can get a $1500 rebate from ONG on a conversion or new vehicle purchase and $2500 rebate for on home fueling stations

There's a place out in Harrah off NE 23rd street that has started doing CNG conversions.

I was surprised a few months back when I saw a CNG fill at the On Cue at 29th and Sooner.
