Well I drove up to the Poudre Valley Coop in Fort Collins today. Noticed the Blue Sun bio-diesel right away. There is a small island with 3 pumps. Kerosene, off road and bio-diesel. Each pump had it's own Cimtek filter on the hose.The bio was going for 2.30 and the # 2 was 1.99.9. So a .30 cent increase. Never the less I wanted to try it.

Pumped in 15g on top of 10g #2. So close to a B10 mixture. ( 10% bio diesel90%petro.) I added some winter diesel fuel additive just to be on the safe side.

I could smell the fuel on my hand right away. It had a more pleasant smell as when compared to #2. After driving for about 3 minutes I could already smell the difference in exaust. It had a fryer type of smell to it but much cleaner.

I have only put about 25 miles on the truck. It runs exactly the same as far as my guages and the seat of the pants dyno. Starts and shuts off the same. The only difference I could tell right away was the engine was quiter. It had less of that diesel rattling/clatter/knocking. Could be because the increase in cetane?

I plan on using the B20 ( 20% biodisel,80% petro) for a few thousand miles. Curious to note any long term changes.

we tried to make bio-diesel once it turned thick and black and smelled like a deep fat frier.... we shouldnt have had a stoned high school kid do the measuring

Hemp would probally make great biodiesel. From what I can remeber that stuff is very oily.

The Bluesun biodiesel is crysal clear and does not smell like fast food. It does have a unique aroma though.

Why the mix of bio with #2 and not just straight bio?
thanks

Well first of all, in my area it already comes premixed at the pump. So you have no choice.

Secondly even though it is only 20% there is still benifit. Increased lubricity, cleaner emmisions, support local farmers ect. ect.

Another reason is that biodisel has less btu. So running a mix allows you to keep most of the pep. while still gaining the other items mentioned above.

There are many who run straight bio, but I would not be that brave with my expensive dmax engine.

Here is a great link explaining more about bio. It covers some technical aspects but still easy reading.

I just bought 5 gallons of B100 to use as a lubricity additive ($2.75 a gallon). I only added 1.5 gallons to a tank, but I can tell it is quieter already. I don't notice any difference in exhaust smell.

There is only one place near me that will be selling B20 (Opens next week. A card lock kind of place). I think I will be buying fuel there when I can. It isn't much more expensive than regular diesel, it is better for the environment, helps farmers, screws the oil cartels out of a couple of bucks, and is better for the truck.

I live in Fort Worth. Where did you buy the B100? Where is the B20 going to be sold?

Thanks!

Bronco- I'm in Ft. Collins. Where was that pump again? I want to give it a try.

Poudre Valley Coop is located on the West side of I-25 just north of Mulberry
( highway 14.)

The pump is located on the southeast corner of the property. There are 3 pumps, Kerosene, #1 and B20 biodiesel.

They did tell me that April 1rst they would have B100.
