I bought a Suburban this week. 1999 GMC K2500 SLT. When you run the VIN# it comes up as a CNG ready. Compressed Natural Gas. The vehicle currently runs on gasoline and we have looked under the truck and we dont see any extra lines or an extra fuel tank.

 

What does CNG ready mean? How is the truck different?

Our USDA government Ford was and alternative fuel CNG truck. It had a separate CNG tank injectors and fuel lines gas neck; basically two fuel systems. There was a switch on the dash board to switch from CNG to gas. You couldn't run it on CNG solely, something like every other tank had to be run on gasoline to keep the seals good in the fuel lines. The problem with CNG is, in Pittsburgh there is no place to fill it up and I imagine it is the same in many other parts of the country.

I wish I could run my Yukon on CNG. The city where I live the city government vehicles run on CNG including a large fleet of Police cruisers. All of the Mail delivery trucks also use it.

 

The city has refueling stations at every Water treatment plant, Plus If I wanted I could purchase the equipment and have it installed at my home for self refueling.

 

At one time CNG was a lot less than a gallon of gas, But today I doubt it. I have not really looked into it since about 6 -7 years ago.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.
