Compressed Natural Gas, or CNG, was initially deployed as an automotive fuel in Italy during the inter-wars period, and is currently pointed as one of the easiest-to-implement measures to reduce the dependence on Middle-East oil, alongside ethanol. It's usually extracted from fossil reserves, either in oil wells or isolated, but since its basic component is Methane gas it can also be sourced from any organic matter residue in landfills and wastewater treatment plants. It's often also pointed as more sustainable than ethanol and biodiesel, because its impact on food prices and availability is lower. The main markets for CNG-powered vehicles nowadays are India, Pakistan, Argentina and Brazil. Their presence in Europe and the USA is increasing in commercial vehicles, but is still not so popular among private car owners due to the lack of refuelling stations in spite of the availability of Natural Gas as for stationary applications such as power generation, home heating and cooking fuel. Anyway, the folks at Ecomodder and CNGChat might like these ones...
Detoilet Detroit Diesel which had some overheating issues and was more expensive to overhaul than the Diesel engines used in its opponents, leading a handful of owners to repower them with engines from other similarly-sized trucks such as the MWM Sprint 4.07 TCA used in the S10 from '99 to '05 and the Toyota 3L and 5L-E from the Hilux. Many of the surviving gasoline-powered ones had been converted to CNG, such as this one with extended cab and the V6 engine.
