Frequently Asked Questions
Propane gas has no odor of its own. The propane supplier adds a distinctive smell so you can detect even small amounts of leaking propane gas.
Q. What should I do If I smell Gas?
Get out of the house immediately. Do NOT smoke, strike a match, or switch anything on or off. Do NOT use the telephone. Call your local propane dealer as quickly as possible from a neighbor's phone.
Myth: How will Biodiesel be priced?
Fact: The most asked question is: Will biodiesel be cheaper? We must realize there are two markets that make our price. There is the crude oil market that determines the diesel fuel price, and the seed or animal fat oil market that determines the biodiesel price. These two together and the percentage of each determine the price of biodiesel.
Myth: Biodiesel is an experimental fuel and has not been thoroughly tested.
Fact: Biodiesel is one of the most thoroughly tested alternative fuels on the market. A number of independent studies have been completed with the results showing biodiesel performs similar to petroleum diesel while benefiting the environment and human health compared to diesel. That research includes studies performed by the U.S. Department of Energy, the U.S. Department of Agriculture, Stanadyne Automotive Corp. (the largest diesel fuel injection equipment manufacturer in the U.S.), Lovelace Respiratory Research Institute, and Southwest Research Institute. Biodiesel is the first and only alternative fuel to have completed the rigorous Health Effects testing requirements of the Clean Air Act. Biodiesel has been proven to perform similarly to diesel in more than 50 million successful road miles in virtually all types of diesel engines, countless off-road miles and countless marine hours. Currently more than 300 major fleets use the fuel.
Myth: Biodiesel does not perform as well as diesel.
Fact: One of the major advantages of biodiesel is the fact that it can be used in existing engines and fuel injection equipment with little impact to operating performance. Biodiesel has a higher cetane number than U.S. diesel fuel. In more than 50 million miles of in-field demonstrations, B20 showed similar fuel consumption, horsepower, torque and haulage rates as conventional diesel fuel. Biodiesel also has superior lubricity and it has the highest BTU content of any alternative fuel (falling in the range between #1 and #2 diesel fuel).
Myth: Biodiesel doesn't perform well in cold weather.
Fact: Biodiesel will gel in very cold temperatures, just as the common #2 diesel does. Although pure biodiesel has a higher cloud point than #2 diesel fuel, typical blends of 20% biodiesel are managed with the same fuel management techniques as #2 diesel. Given our state temperature range, we should have no problem with 20% blends.
Myth: Biodiesel causes filters to plug
Fact: Biodiesel can be operated in any diesel engine with little or no modification to the engine or the fuel system. Pure biodiesel (B100) has a solvent effect, which may release deposits accumulated on tank walls and pipes from previous diesel fuel use. With high blends of biodiesel, the release of deposits may clog filters initially and precautions should be taken to replace fuel filters until the petroleum build-up is eliminated. This issue is less prevalent with B20 blends, we plan to use a standard B20 blend as our main fuel and will keep clean filters on all our tanks. This should stop most problems before they arise. Most clogged filters are a result of off-spec biodiesel which does not meet ASTM D6751 requirements.
Myth: Engine warranty coverage would be at risk.
Fact: The use of Biodiesel in existing diesel engines does not void parts and materials workmanship warranties of any major US engine manufacturer. We have letters on file from John Deere, Case IH, Cummins, etc. Each of these companies states that if the fuel meets the ASTM D6751 standards, that the warranty will be in place. Our production facility will be the best, and our fuel will meet all these requirements. We plan to be both a BQ9000 producer and a BQ9000 Marketer. This means that Scott Biodiesel will not void your warranty.
Myth: Biodiesel does not have sufficient shelf life.
Fact: Most fuel today is used up long before six months, and many petroleum companies do not recommend storing petroleum diesel for more than six months. The current industry recommendation is that biodiesel be used within six months, or reanalyzed after six months to ensure the fuel meets ASTM specifications (D-6751). A longer shelf life is possible depending on the fuel composition and the use of storage enhancing additives.
Myth: No objective biodiesel fuel formulation standard exists.
Fact: The biodiesel industry has been active in setting standards for biodiesel since 1994 when the first biodiesel taskforce was formed within the American Society for Testing and Materials (ASTM). ASTM approved a provisional standard for biodiesel (ASTM PS 121) in July of 1999. The final specification (D-6751) was issued in December 2001. Copies of specifications are available from ASTM at http://www.astm.org.
Myth: Biodiesel causes degradation of engine gaskets and seals.
Fact: The recent switch to low-sulfur diesel fuel has caused most Original Equipment Manufacturers (OEMs) to switch to components that are also suitable for use with biodiesel. In general, biodiesel used in pure form can soften and degrade certain types of elastomers and natural rubber compounds over time. Using high percent blends can impact fuel system components (primarily fuel hoses and fuel pump seals) that contain elastomer compounds incompatible with biodiesel, although the effect is lessened as the biodiesel blend level is decreased. Experience with B20 has found that no changes to gaskets or hoses are necessary.
