bio-diesel with 04 Duramax?

[Scott Duprey]

My point is I have nothing to gain or loose financialy by promoting soy bio-diesel.

Just as I have said before soy bio-diesel elliminates the need for fuel additives. Some have things to gain by bad mouthing it.

Each load of soy bio-diesel that is delivered is tested.

Good luck.

Well I finally had a chance to try it. Added 9.5 gallons of B20 (down in Tucson at AZ petroleum) to the dyno diesel. A very rough estimate that I would be close to the B5 allowed by Chevy (still haven't done that math and it's Friday night...). I'm pleased with the results. My truck was purring down I10 the following weekend and doing the MPG math, I was up 20% or better. Will I do it again? You bet. Will I fill a whole tank with B100? Probably not.
Cheers,

We have recently started recieving an unusual amount of orders for fuel filters that contain heaters. It seems that several people are buying these filters in order to run the vegetable oil in their diesel. I started researching this and found this article: http://energy.cas.psu.edu/soydiesel.html

This article seems to spell out my concerns with the use of these "homemade" fuels. While I love selling the filters I am concerned about the long term damage of burning fuels that have not been mixed properly. Several years ago we heard a lot about blending used engine oil with the diesel fuel as a way to dispose of the used oil. Several people just started dumping it in at their own levels while others purchased blenders that actually blended the two in proportionate amounts. Over a period of time we saw a lot more damage from the self mixed fuel than from the blended.

I would like to hear more from people that are burning the various fuels and what their experiences have been.

I would not recomment anyone use home brew. That is looking for trouble. I've heard it is the home brew stuff that has a lot of water in it.

The soy diesel I get from Growermark is tested and had way below the norm of water in it.

1000's of customers with 1,000,000's of miles driven all all different types of trucks. NOT 1 single problem.

I can see the fuel station in my town from my office. Fords, new old, Duramax's new and old, Dodges new and old day after day stop and fill with 2% bio-diesel. If this stuff was crap we would be out of business and that is not going to happen.

@70,000 miles on mine now running b2 and going strong.
