581:(United Kingdom) and "power kerosene" (Australia). Often the tractors were referred to as "all-fuel". The most important factor in burning heavy fuels in a spark-ignition engine is proper fuel vaporization. Tractors designed to run on those fuels usually used a "hot" intake air manifold that allowed exhaust heat to warm the manifold and carburetor to aid vaporization. Given the poor vaporization at low temperatures, all-fuel tractors were started on gasoline, then switched to the heavy fuel. They were equipped with a small gasoline tank and a large fuel tank, both of which fed into a common valve supplying the fuel to the carburetor.

570:, drip gas was used as a replacement for commercial gasoline by people in oil-producing areas. "In the days of simple engines in automobiles and farm tractors it was not uncommon for anyone having access to a condensate well to fill his tank with 'drip,'" according to the Oklahoma Historical Society. Sometimes it worked fine. "At other times it might cause thundering backfires and clouds of foul-smelling smoke."

processing plant. These hydrocarbons include ethane, propane, butanes, and hydrocarbons with five or more carbon atoms – referred to as pentanes plus, naptha, or plant condensate. Plant condensate can also be blended with crude oil, which would change both the distribution and total volume of oil received by refineries.

A final point to consider involves the distinction between the very light grades of lease condensate (which are included in EIA's oil production data) and hydrocarbon gas liquids (HGL) that are produced from the wellhead as gas but are converted to liquids when separated from methane at a natural gas

The use of drip gas in cars and trucks is now illegal in many states. It is also harmful to modern engines due to its low octane rating, much higher combustion temperature than that of gasoline, and lack of additives. It has a distinctive smell when used as a fuel, which allowed police to sometimes

Natural gas condensate is generally more flammable and explosive than normal crude oil. Operating in areas where condensate has escaped is dangerous for crew due to the danger of explosions, oxygen displacement and the threat of asphyxiating and anaesthetizing, which can occur within a few human

The engine would be started on gasoline and the tractor would then be worked until the engine was sufficiently warm to change over. At that point, the fuel valve would be turned to switch the fuel supply from the gasoline tank to the fuel tank and the heavy fuel would flow to the carburetor.
