Thanks for the post, methinks this is a subject we all need to take a better look at and give serious consideration. I would love to be involved in road testing. Regards Dave

I was following a 16 or so foot unmarked white Volvo diesel on the expressway day before yesterday, and I was assailed by the strong odor of french fries! I passed him and the smell went away; dropped back, and there it was again. Could I have been following a truck running on bio? Is this fuel out there for use yet? I guess it might have been a research vehicle for someone--I didn't get a look at the tags. I have heard that Georgia Tech is involved in this research--could have been them. Gotta say, though, I did have an overwhelming desire to go to McD's soon after!

One thing I have noticed about running B20 is that the idle quality is "choppy" compared to #2 diesel. Not a huge difference, but noticeable.



Anyone have an explanation? lower BTU?

I have been running a lot of B20 and have not noticed that my idle is "choppy". What I have noticed is that the truck runs better at higher rpms.



When I first started making the stuff, I remember people saying that you had to retard the timing just a little bit in most diesels to get it to run just right. I wonder whether this could have anything to do with your "choppy" idle. I am sure that other people would know a lot more about this than I would.



Biodiesel is gaining in popularity and if anyone is interested in trying the stuff, take a look at the distributors map at http://www.biodiesel.org/buyingbiodiesel/distributors/



There is also a lot of good info on it in the alternative fuels section of this forum. It really is neat stuff.

EKlem, Is your timing still at the OEM spec? Mine is @ 14. 5 BTDC. This could explain it.

Yes. Just before I bought the truck, the injection pump was replaced and the timing was set to factory spec.

gelling character

Freeze points/cloud points were not mentioned. I would love to run a bio, however freeze points from my understanding are not compatable with my climate.

Champane, I run B20 every 3rd tank or so and have had no problems. My truck does sleep in a garage, though, so it doesn't normally sit for long hours in single-digit or below weather.

I live in Nederland @ 8300', have had my truck since november, I have been running B-50 or more all winter. Last night went down to -10 or so. Started right up in the morning (plugged in) at about 0 F.

you should have no trouble with b-20

Give er a try!

Okay guys i have one question and that is about orings and fuel lines deteriorating since cooking oil makes certain types of rubber mushy. . any thoughts on this? As i have several resturants nearby that i can tap into and have a endless supply...



thanks

As far as I know, running straight vegetable oil does not affect rubber parts. Biodiesel does tend to eat rubber(I think that it has something to do with the excess methanol) so in high concentrations, you have to be somewhat careful but B20 is no problem. All newer vehicles have lines that are not natural rubber but a substitute so they don't have problems but I don't know when they switched to that.



As far as the cold goes, I can't plug in here at school in NH and it gets plenty cold but I haven't had any problems with up to B20.

Like hugging your sister...?

I think B20 is only a twenty percent bio, and the rest is petro? If I wanted to go green, I would want to make my own. That and not have to buy my additive by the barrel, you just kind of defeat the purpose? I guess a warm climate and your own brewery would suit bio lovers all... Love the idea, the results, but, am not going to sludge up every winter, or end up putting terpentine in my bio to bring the gell point down. .

There was a supplier in Atlanta back in the fall for B20. I have been running it in both my 12Vs since October. I don't have a choppy idle and so far both trucks are getting 2mpg better than they did on winter #2 last year. Now that I have my DTT in I am going to test the more power theory of #2, but I really have not seen any difference in power-just less smoke.

I have a friend who has a 2001 SO automatic and he is getting 1 mpg better on B20 than #2 winter fuel.

I am getting ready to reset my timing. DTT recommends 15. 5. I was wondering if I could go a little higher using B20.
