Filtered HD-5 Propane

Southern Indiana Propane purchases only HD-5 Propane, the best grade available. To provide an extra level of quality assurance to our customers, we filter every gallon. The use of filtration at all transfer points polishes the propane to remove any impurities that may have been picked up in the transportation of the product from its source to the bulk storage tanks of Southern Indiana Propane. As a leader in safety and quality, we believe that it is important to do all we can to supply our customers with the most reliable and cleanest form of energy, then filter it to provide many years of trouble free operations.

We strive to bring our customers peace of mind through the best safety practices in our marketing area and the delivery of the cleanest and best fuel we can provide. Others may occasionally have a cheaper price, but are you also receiving a cheaper product that burns less efficiently and leaves deposits in your propane equipment that shortens its life? Our attention to quality helps to provide the safest environment for cooks and the food they are preparing by reducing the potential for impurities in the vapors of combustion. Southern Indiana Propane won't take shortcuts with your safety or the quality of the propane that we provide.

For more information, please call and ask to speak to a propane professional.

What is CGX-4®

CGX-4® is a highly effective additive for propane engine fuel that improves the burning characteristics of LP-gas for better performance and economy. Much like detergent additives in gasoline keep your engine free from gunk, CGX- 4’s® unique cleaning power removes harmful deposits and prevents future buildup of long chain hydrocarbons and other contaminants that cause combustion problems, inadequate upper end lubrication, and pre-ignition in the combustion chamber. Costly repairs and downtime are greatly reduced.

How does CGX-4® work?

CGX-4® has combustion-improving compounds that minimize pre-ignition in the combustion chamber prior to spark plug ignition of the fuel mixture. it also provide a more even burn upon ignition, increasing the efficiency of fuel combustion. Results include: higher pressures in the combustion chamber, increased power, more efficient fuel economy, and a very significant reduction in carbon monoxide, nitrous oxide, and unburned hydrocarbons in the exhaust gasses.

LPG often causes a buildup of long chain hydrocarbons in the engine’s vaporizer and carburetor systems. As buildup increases, the fuel does not vaporize effectively. The emulsifiers in CGX-4® slowly soften and remove buildup, which can interfere with engine operation. This oil-soluble substance holds insoluble foreign matter in suspension so the heavy ends are carried through the vaporizer and carburetor and are burned during the combustion process. A surfactant takes care of free water found in most LPG by dispersing the water and other liquid impurities into colloidal-size particles in the LPG. The emulsifier retains the suspension through to final ignition, after which it is expelled with the exhaust gas.

CGX-4® components lubricate the moving parts in the top of the combustion chamber that are not lubricated by crank case oil. This top oil is not completely vaporized in the combustion chamber because of its high flash point of 425°F (218°C). This results in a light film coating to the cylinder walls, rings, and valves. The added lubrication increases engine efficiency, reduces operating temperatures, and prolongs engine life. Another noted benefit is extended life to all diaphragms, gaskets, and rubber parts due to the permeation and conditioning effects of top-oil.

Call Before You Dig

Digging blindly can be dangerous and expensive. When you plan to dig, the law requires that you phone the Indiana Underground Plant Protection Service (formerly "Holey Molely") by dialing 811.

Southern Indiana Propane will also be happy to come out and locate our underground lines. Please call us at least two (2) business days before you plan to dig.
