For all you New England'ers; Newport Biodiesel sells for about $3.00/gal (RI)

Bio typically has about 15% less BTU content than highway diesel...so you'll see a loss of power and mpg of about 15%

The source of oil does make a difference, but I dont *think* there are any "natural" oils that are as potent as our friends in the middle east

 

How does someone get rid of Glycerol?

I remember watching Trucks! a few years ago when Stacy was the host. Cool episode showing how it's made. Seems like the byproduct of Bio was used to make soap.

 

I liked the smell of french fries from the exhaust.

But I read in a reputable source that biodiesel did not lubricate the injectors as well and should have a lubricant added. I assume 2-stroke oil would work.

Haven't run any since reading that. I'll have to see if I can find the source of that information, it is the loose leaf 7.3 manual.

 

Biodiesel does the opposite, it lubricates more.

 

It's not this lubricity study is it?

Holy cow, not too many people will know where Ennis is, lol. But all those different fuels are definitely out in those farming communities in Montana

 

A nice 89-1.00 savings a gallon would make up for the loss in mpg to me...Do you know if they sell it right at their Connell highway location?

Hmm...I was always under the impression it was the opposite...if you could dig up the link that would be awesome.

Yeah I went cross country with my then girlfriend, now wife, a few years ago and I completely fell in love with western Montana. So nice out there, totally blows Massachusetts out of the water IMHO...don't think I could sell it to the wife though and CPA firms are few and far between out there....

 

I'm not sure which station sells the bio...I can find out this weekend....I'll probably stop there and fill my tank with some pure bio if i can. only problem is my fuel filter has about 3000 miles on it.....and I dont have a spare

 

I googled them and found this distributor...closer to me at least.

T.H. Malloy & Sons - Retail Pumps

 

$3.65 isn't much of a deal....I think I'd rather run regular diesel at that price and keep the power/mpg up

 

No, not at all. Especially for you. Little longer ride than me.

 

I thought I would do a quick analysis of a comparison of Diesel #2 to biodiesel...

From research done by EPA:

Diesel #2 (D2): BTU range of 128,000 - 130,000
100% biodiesel (B100): BTU range of 117,000 - 120,000

So let's use mid values for both...

Diesel #2 = 129,000 BTU
100% biodiesel = 118,5000 BTU

129,000 BTU - 118,500 BTU = 10,500 BTU difference between D2 and B100

118,500/129,000 = 0.92 or B100 has about 92% of the energy content of D2. To be of equal value per BTU the B100 would have to be 8% cheaper per gallon than the D2 to be equal value per BTU.

Example: D2 = $4.00 per gallon, so B100 would have to cost ($4.00 x 0.92) or $3.68 per gallon to be of equal value per BTU

So Trey used B20:

(20% biodiesel + 80% D2) and it has a BTU content of (118,500 x 0.20) +
(129,000 x 0.80) = 126,900 BTU

126,900/129,000 = 0.98 which means the B20 Trey used has 98% of the energy content of straight Diesel #2. On a per BTU basis the B20 would have to be 2% cheaper than the D2 to be of equal value per BTU.

Example: D2 = $4.00 per gallon, so B20 would have to cost ($4.00 x 0.98) or $3.92 per gallon to be of equal value per BTU

This also means that Trey should experience about 2% less fuel mileage (mpg) using this B20 over using D2 on an exact same course in the exact same conditions.

Example: If Trey averaged 15 mpg on D2 he could expect to get (.98 x 15) = 14.7 mpg using B20

 

sounds like a large loss on mpg. im brand new to this site. if i want to make my own bio deisel and have the resources to p/u the used oil unfiltered. how much used oil does it take to make 50 galons of bio diesel?

 

Using a 50 gallon processor, I fill with 37.5 gallons of oil and yield between 30-33 gallons of bio, depending on the quality of the oil...

 

i dont run Bio because it is 0.17 more than D2 and the only place that sells it is 150 miles away.
