The higher the fuel's octane, the higher the maximum compression ratio of the engine and the greater its efficiency. Many drivers of dedicated Natural Gas vehicles experience improved acceleration. Since Natural Gas is in a gaseous form, it mixes well with air. In cold weather, Natural Gas actually starts better than a gasoline or propane vehicle. The fuel that heats our homes and offices is also a proven vehicle fuel used around the world for the past 50 years.
Natural gas is a safer vehicle fuel than either gasoline or propane.
Because it has a higher ignition point, it is less likely to ignite accidentally. Lighter than air, natural gas does not settle in low lying areas, as heavier propane or gasoline vapours do. In the unlikely event of a leak, natural gas dissipates rapidly rather than pools. This is why it is safe to park your NGVs in underground and enclosed parking garages. Unlike gasoline, natural gas is not toxic and, in most applications it is safer than gasoline.
