I don't have a "dodge engine" I have a cummins. cummins says b20 is fine. I'll listen to the folks who make the engine.
The hysteria in that other post over Bio fuels, is some old info. No matter the fuel if it is old or not stored properly will deterate and cause proublems.
Algae will grow in straight diesel fuel also.
It all comes back to how it is stored and how old the fuel is.
A ? for you. what happens when you go to a state or live in one that has by law over 5%bio in the fuel?
When I did have a DPF I had no choice but to run bio.
Now my state is going to mandate B20, so regardless of dodges position you would not have a choice.
And even if I and you did use def fluid (urea) we would still have a DPF. It is the DPF that is limiting your use of Bio fuel as the DPF needs the heat from burning the diesel fuel to burn off the soot in the dpf. Bio fuels are lower in BTU's and this is the concern. because it will not burn off the soot completely if to much bio is used.
But cummins says b20 is fine to use.
Biodiesel Blend Mandate
Diesel fuel sold or offered for sale in the state for use in internal combustion engines must contain at least 5% biodiesel (B5). Beginning May 1, 2012 or when certain conditions have been met, during the months of April through October, diesel fuel must contain at least 10% biodiesel (B10)
. By May 1, 2015, diesel fuel must contain 20% biodiesel (B20) during these months. Diesel fuel sold during the remainder of the year must be B5. The Minnesota Department of Agriculture, Department of Commerce, and the Pollution Control Agency, in consultation with the Biodiesel Task Force
and other technical experts, may allow the higher specified biodiesel blend levels to be effective year round if determined that an ASTM specification or equivalent federal standard exists for the specified biodiesel blend level that adequately addresses technical issues associated with Minnesota's cold weather and publish a notice in the State Register to that effect. Additional exceptions may apply.
It does say B5 on p66 and in MN we already have been using B10, so now what?
