CNG advertising

CNG (compressed natural gas) was very popular in the early 1980s as an inexpensive alternative to petrol, which was costly due to high oil prices. The government offered low-interest loans for the conversion of motor vehicles to CNG. However, conversions were not cheap (costing on average $3,500 in 2005 dollar terms). As oil prices dropped in the late 1980s, CNG lost its cost advantage.
