• Properly maintained, propane-fueled engines produce less air pollution than gasoline or diesel engines, according to studies conducted by the U.S. Environmental Protection Agency.
• Propane is clean burning. It leaves no lead, varnish, or carbon deposits that cause the premature wearing of pistons, rings, valves, and spark plugs. The engine stays clean, free of carbon and sludge. This means less maintenance and an extended engine life.
• Propane does not have the dangers (such as fumes and spills) associated with gasoline or diesel fuel.
• As a vehicle fuel, propane does not require the additives that are usually blended into some grades of gasoline. Even without additive boosters, propane has an octane rating of 110, which is equal to and, in most cases, higher than available gasoline.

The PERC Agriculture Advisory Committee is pleased to announce the launch of a new online tool to help growers estimate the cost-saving advantages of using propane. The Agriculture Cost Estimator is a new web-based tool that allows growers and propane dealers to quickly compare the cost of using propane to the cost of using other energy sources in two common applications—grain drying and irrigation.
