Diesel Power
It is a blend. I will get more info from the fuel manager, ie blend%, possibly B10. This source is an agriculture business. He informed me that he was getting a lot of request for biodiesel. They have provided it for sometime to agriculture users.
I have driven only about 75 miles on it so far, it does appear that the DIC is showing a slightly lower MPG, it war 29F yesterday AM and it started right up the same as always, power seems the same. Too early to give a real opinion. I have read an article on soy bean biodiesel and it is supposedly to have a significant higher lubricity. I will quote below.
"Biodiesel also contributes to an engine's lubricity, or its ease of movement. Biodiesel acts as a solvent, which helps to loosen deposits and other gunk from the insides of an engine that could potentially cause clogs. Since pure biodiesel leaves no deposits of its own, this results in increased engine life. It is estimated that a biodiesel blend of just 1% could increase fuel lubricity by as much as 65% (U.S. DOE Office of Transportation Technology)."
Storm Chaser, this is for your concerns.
"Another problem is biodiesel's behavior as a solvent. Though this property is helpful, it's kind of a double-edged sword. Some older diesel vehicles (such as cars made before 1992) may experience clogging with higher concentrations of biodiesel. Because of its ability to loosen deposits built up in the engine (which may be there from old diesel fuel), biodiesel can cause the fuel filter to become jammed with the newly freed deposits. Biodiesel manufacturers suggest changing the fuel pump shortly after switching to high-concentration biodiesel blends. Components within these older fuel systems may also become degraded. In addition to deposits within the fuel system, biodiesel also breaks down rubber components. Some parts in the older systems, such as fuel lines and fuel pump seals, may become broken down due to their rubber or rubber-like composition. This is usually remedied by replacing such components. Though many manufacturers have included biodiesel in their warranties, potential for problems could still exist."
"Also, in some engines, there can be slight decrease in fuel economy and power. On average, there is about a 10% reduction in power. In other words, it takes about 1.1 gallons of biodiesel to equal 1 gallon of standard diesel."
