is biofuel worth the fuel discount?

So what's the real story on the small amounts of moisture in biofuel freezing and causing damage to fuel system components, such as unit injectors high pressure pumps etc.

 

Shouldn't even be an issue if your fuel/water separator is doing its job.

 

I hear more of it on the equipment side of things. Mostly tier III and IV. We done several common rail systems this winter that moisture freezing in the small passages was blamed for several thousand dollars worth of repair. I have used the same diesel shop for many years and believe in them. But may be misinformed about biofuel to a certain degree.

 

If you have the newer trucks with the extreme high pressure rail system (29,000 psi) your restricted to B5 or B20, all depending on your engine manufacturer.

 

Biodiesel contains 8% less energy per gallon than typical No. 2 diesel in the United States and 12.5% less energy
per pound. The difference between these two measurements is due to the higher density of biodiesel compared
with diesel fuel. All biodiesel, regardless of its feedstock, provides about the same amount of energy per gallon or
per pound.

This is why your engine runs cooler, since its producing less energy, but when fully loaded and uphill you will notice the 12.5%

 

sheesh

all this time i thought the spinach juice was winterizing for the fuel

 

I'm strictly talking about B100(just biodiesel) here, if your running B20 or less, you shouldn't really notice anything, other than great diesel additive.

Around here you can save about $1 a gallon with B100, ran it for months no issues. Also, few months back there was a 1K credit for using biodiesel, saved a few bucks.

The cetane rating does help with winterizing(B20).

 

I wasn't aware there were trucks that could run on b100. Where is here for you?
