I have a 2004 chevy silverado 3500 (6.6L duramax diesel) And its all stock. Are there any conversions needed to run biodiesel? any ill effects? What is the most biodiesel that i could use in this truck per fill-up mixed with regular diesel or would it be possible to use %100 bio diesel? where are some stations in the north florida area?

Thanks

Fuel filters. You might consider putting on a BIG fuel filter like the Cat's that come with the Nicktane kit. The Bio will clean the fuel system and clog up the little stock filter.

GM says B5 (5%) max. I've only had access to Bio once and got it to about 30%-40% and the truck ran very nice/quiet. But that was only once. I would love to run about B20 all the time (at least I think I would).

Others will have to give you their experiences of running higher or pure all the time.

Your truck will should be fine if the fuel is properly processed and is dry.

I have almost 30K on B50-B100... No major problems.

You can find a retail source here...

Cheers.

So it would be okay to run B100 at %100 with no regular diesel? why does GM say you can only use it at 5%

5% is GMs Warranty cop out... that's all.

They want to blame anything except THEMSELVES and the fuel used is an easy target.

I've run 50% in my 2004 (LB7) only a couple of times but man, like the other guy said WAS IT EVER quite!!! Looking to run it more, and just getting started making some fuel myself. I guess I need to wash that 40 gallons sitting in my shop!!! $3.77/gallon last night for ULSD...

I agree that an extra fuel filter would be smart, though the 35 gallons I've burned showed no ill effects on the filter. I have the parts to do mine, just haven't gotten it done. Bio or no bio I'll be a lot happier changing $12 spin ons that are easy to access underneath the truck than that pricey OEM unit...

Frank, I have been running 100 percent for about a month now with no ill problems. It does gell under 40 degree weather and it does clean your tank out. But to better manage that I installed a pre oem 2 micron filter that cost 13.59 each verses the 15 micron oem filter for 25 to 45.00. So far I have ran 900 miles with one filter change. Go to Biodiesel.org to find a retailer or do what I did and buy it cheaper, in 250gallon totes, from a distrubitor.

Who makes the filters you were talking about and what is the part number for it?

Thanks

Baldwin #7587 fuel filter. I would gave you the link but The mods would after me! :eek: Pm me if you want to.

Thats BF7587.

What's that costing you?

3.06 dollars a gallon as of 03/05/2008 I found a distrubitor at Biodiesel.org in Theodore,Al.

Thats BF7587. That filter seems to be a lot bigger than the stock filter, are you using that under the hood or as a secondary bypass filter?

I installed it and a lift pump on the frame rail in the suction line.

How long does it take you to use this amount of diesel? Do you find that you have problems with it drawing water if you don't use it up fast? I heard that you cannot just leave it sitting around because of the water issues.

No water problems as of yet, 02-22-2008, I have used 100 gallons of it so far. IMO, I don't think Biodiesel collects any more condensation being stored for long periods of time, than Dino Diesel. I use a clear hose to my pump, so I can see what is going on, then it goes through a 10 micron filter to the tank of the truck.

How do you have the filter hooked up so that it filters before it goes to the truck? Id imagine if you do that there is no need for a secondary in line filter on the truck.

Most diesel pumps have filters between the pump and the nozzle. On my transfer tank I added a filter in the same way, it filters it coming out of the pump before it goes into the hose.

I've been running B100 fro about 5-6 weeks now, other than having to change the OEM filter out within the first half tank (it was about due anyway), it runs like a dream. Going to start making my own soon as I can find a place to do it from.

I have a filter on the discharge side of my transfer pump coming from the biodiesel storage tank. Its a wix water block filter. As far as why the secondary filter on the truck, so when I first put in biodiesel in the tank it will clean out all the diesel crud that was deposited there from previous fill's of dino Diesel. And to catch any other debris that might find its way to the very expensive injectors and CP3 pump. I now have 250 gallons of biodiesel useage with one Baldwin bf7587 fuel filter change and no other problems.

whats the diffrence between b100 and say b99 or b20.. what is better?

The number represents the amount of bio.. Ex., B20 = 20% bio/80%#2.

I cannot tell you what is better as I have only run B20, but my truck seems to like it.

Any blend of Biodiesel is best in any diesel. It has the best lubrication for the CP3 pump compared to any other diesel additive. IMO. Read in maintence and fluids forum on Spicer's report.

Yea, the 2% Bio is the best additive out there. B100 or B99 burn cleaner than B20 or straight dino.

You can never filter any diesel too much, and the way I look at it the Baldwin is cheaper to change than stock. I'm thinking about putting two baldwin's on, one 10 microns and one 2 microns, maybe overkill, but if I don't have to change the OEM but maybe every 35-50k I'm $ ahead, plus the IP and injectors should last a lot longer.

5% is GMs Warranty cop out... that's all.

Exactly. And this is why if you do run a high percentage of bio-diesel, and have any problem they might try to attribute to the fuel, you should make sure there is no easy way for them to find out that you've been running bio-diesel. Before taking in for service, run it down to as nearly empty as possible, and then fill up with petro, run it to nearly empty again and then change the fuel filter.

what does the milage do with bio? up , down the same

same,,, what you lose in BTU's you gain in extra lube,,, I havent noticed a diff myself

Well, I have had a loss of about 1-1.5 mpg. Due to the less BTU's in Biodiesel, But I have also found that the less biodiesel used the better the miles per gallon. In my case, B40 I only lose about .5 mpg and thats a round about figure due to the lead content in my foot. :D And also, you lose some performance, but the trade off is the BEST lube for the expensive parts ahead of the filters. Cp3 injection pump, fuel injectors.
Steve

do you lose any HP and if so do you notice it much?

Graydon Blair from UtahBiodiesel,, said that the fastest diesel use's B20 at the track. He also said that B20 is about the best mix for performance applications,, So I'd say using B20 you might notice a little better than none. But your truck will sound better with anything over B10 and it will like it. My truck is really going slower now I'm using a higher mix of Bio,,,, My wallet is heavier now, and thats slowing my truck down!!

well im not really racing or dragging. but i do like to show all my friends that my duramax is boss over the gassers and the cummins every once in awhile. so if i ran B100 would it take me down like 30hp? anyone have a clue?

I have noticed a loss of HP, But I could not tell you how much. Its one of those seat of the pants type things. At the same time I want to believe that if you had EFI live software you could possibly tune for better mpg.
The programers that are out there are tuned for Diesel. Are they not?
Steve

so with my bully dog on like 80 or whatever its adding it wont work with the biodiesel? is that what you are saying?

No, what i am saying is that if you had eFI you could program BETTER that the Handheld programmers. I use predator on 65hp most of the time ( sometimes higher or lower ) with B100 and now with B40 mix. It works great. If you do try it, expect to clog your fuel filter sooner than normal. The higher the percentage of biodiesel the sooner it will clog the filter, due to the cleaning effect of the Biodiesel.

If your truck was 400 hp with your BullyDog on 80 running straight # 2 then you'd most likely be at 350 hp (10-15% loss) on 100% Bio-Diesel with the BullyDog set on 80.

With EFI Live you could just build a tune to compensate for the hp loss.

i can stil go up one more stage on my bully dog and add about 20 more hp i think. i am going to try BD here soon.

Thanks Eddy, I was hoping someone with EFI Live would help gave an explaination of how it works with B100. :rules:

i was also thinking of making bio but had a lot of questions.really worried about the expensive IP,and drop of hp thanks duration for good info.

do most of yall buy from a co-op or station or do yall make your own?

I was buying mine from a distributor, but they quit selling it. So I'm looking for another wholesaler.

how far is escatawpa from memphis?

nevermind i just mapquested it haha. i was gonna say i would let you know if i found one that was close.

Thanks for trying to help Skiler, I was calling several places yesterday and still no luck. I guess it isn't popular enough down here. YET!
Steve

give www.biodiesel.org a look. and under buying biodiesel it will give you an area within your state of all the places that sell it. it even gives you the blends they have! i found one that is about an hour from my house that carries all blends and im gonna give em a call later on and get some prices.
