is biofuel worth the fuel discount?

i only fuel at pilots blue green fuel doesnt matter
this is all old wives tales bs
the op has a smaller micron filter or algae or sumthin that isnt where he fuels
i havnt changed a fuel filter except when doing a normal service on this 2012 Detroit


everything else is just sit at the counter jawboning

 

That is correct.

 

The "yellow" or gold colored fuel is typically the bio-mass fuel, that comes from animal fats, etc. The green fuel is soy-based, and is the better alternative if you are going to run bio fuels, I have ran it for years with no problems. There is NO bio fuel derived from corn for diesel fuel, you are thinking of ethanol, which is in gasoline.

 

Thank you for correcting me.

 

So if it's "diesel bio ultra LS 5%" what does that mean? Been running it for a few years without issues. I seem to get better mpg elsewhere though.

 

Ultra low sulfur 5% biodiesel
Blend. It's basically 95% diesel #2

 

Should I be running 2 stroke oil in my fuel with this in a c12? I pay 20-35 cents less a gallon than the cash price so an additive wouldn't make it a wash.

 

Biodiesel has better lubricating properties and much higher cetane raitings(what actually counts in diesel fuel additive) today's low sulfur diesel fuels. Biodiesel addition reduces fuel system wear, and in low levels in high pressure systems increases the life of the fuel injection equipment that relies on the fuel for its lubrication. Depending on the engine, this might include high pressure injection pumps, pump injectors (also called unit injectors) and fuel injectors.

Bio-diesel acts as a solvent, completely cleaning out your fuel tank, this is what causes your filter to plug up quickly. After about 3 or 4 uses(depending on your tank size) and your tank has been cleaned out fully, you will be back to normal.

The other pro to using the bio fuel is its energy point. The more you use, the more likely you are to keep your engine running cooler. B50 is a good blend.
With the introduction to cold filtering, you shouldn't run into any gelling issues in the winter anymore. B20 is a good winter blend.

For your fuel filters, ensure your filters are using synthetic filters and not the paper filters. The minute amount of water in biodiesel can rot and deteriorate the paper, causing issues at a much quicker rate(dont buy cheap stuff).

If your truck is older, 15 yrs or so, you will probably be using the older rubber hoses and gaskets, which are vulnerable to the solvent in biodiesel. You'll want to replace them with FKM(Newer rubber or Flouroelastimers).
