My brother and I are going to try to buy a home kit for making bio only thing is that he has an 06 and I have an 01 and our dad is thinking of getting a 07 with the 6.7. Would we all be able to run the same mix. Thanks for any input.

One more thing what kind of MPG's would we be looking at. Thanks again

I'd go for it. Bio has better lube properties and higher Cetane. MPG will be about the same.

You want to make sure of your quality, as the fuel systems on the newer trucks are more finicky than the older ones, at least that's what I have heard. When I have a batch of questionable quality I run it in my 96 rather than the 99. This is more important in the colder weather than now though.

The 6.7 is only rated for a B5 BioDiesel. Id wait a while and do quite a bit of research. Ive also heard that the new high pressure common rail injection system is kinda touchy when it comes to biodiesel. But Ive also read reports of people with newer models running it no problem.
Go figure.

Most of the problems reported with biodiesel in newer engines, or any engine for that matter, is blamed on poor quality homemade fuel.

It seems professionally refined biodiesel is great but the level of quality with homemade fuel is so inconsistent and usually lower than a refinery is that it gives ALL biofuels a bad reputation.

I hope none of this detours you away from wanting to make your own fuel. Im in full support of it. Id try to give it a shot myself but Im in college and I dont think my landlord would like it if I turned the back yard into a refinery.

But yeah, do some more research. Call company's that make the kits and ask them for feedback. Find others who have been running it in similar model trucks and ask for their likes and dislikes.
The important thing is to never stop asking.

Keep us posted.
If you get it all worked out, let us know, I might swing by S.A. and purchase some from ya'll. =D

From what Ive read B100 in these newer high-pressure systems is bad. Supposedly the fuel tends to polymerize under extreme pressures.
In the older motors almost anything goes. One reason I like my dinosaur =)
If you invest in a biodiesel reactor, Id look for plans for the appleseed reactor. Its real simple and theres a complete parts list out on the net. Based around a used electric water heater

Cummins just approved B20 for use in ISB's.

From what I heard, B5 will work with stock 6.7, for b20 to work, you just need to change filter

you can use b20- just change the filters out more. d/c knows you can use at least b20. they are just waiting until there is a national standard for biodiesel fuel-so until that point- they are just trying to cover their butts pertainng to warrany work- if you make a high quality home brew-use it!!! i do!!

Pressure doesn't have much to do with polymerization. The type of oil and amount of oxygen it is exposed to has everything to do with polymerization. Soy based biodiesel is fine, but it's kind of high on the list oils likely to polymerize when exposed to too much oxygen. I believe this is one reason why some manufacturers only warranty canola or rape seed oil based biodiesel -- it has less of an ability to polymerize. There are many more oils that are less likely to polymerize than canola. Properly made soy-biodiesel is fine, I think.

Pardon my ignorance, what's an ISB? And the way I read the press release, Cummins approved B20 in their "Tier 3 emissions-compliant QSB4.5, QSB6.7, QSC, QSL, QSM and QSX engines" Can anyone translate that? What's in my 2006?
I'm also reading about requiring an additiional "water sepeerator" for > B5 blends...maybe "Tier 3" means you have one? Seems like they are approving B20 in "Fleet" vehicles which I am assuming are rigged different that our street trucks off the lot.

I'd love to run B20 which is available here in Richmond. Lots of conflicting info here (or confusing perhaps to me):

- clogs injectors? (because bio is detergent and all the "gunk" built up over time is released into the fuel system).
- clogs filter? (same as above)
- eats away at fuel lines? (contributes to above clogging) Is this a problem in the 3rd Gen engines still?

Is there a biodiesel FAQ I missed somewhere?

Thanks in advance for your replies.

ISB is an acronymn, stands for Interact Systems "B" series. It is what is installed in all 24v 2nd gen Rams. Cummins also had ISC (8.3L), ISM (11L ?) and ISX (15L monster) engines.

QS is the newer designation for common rail engines QSB 4.5 (4.5L) is the 4 cylinder version of the QSB 6.7 (6.7L in the 07+ Rams)

Don't know on the fleet vehicles.

Clogs injectors - Only if anything is making it past your fuel filter.
Clogs filters - yes it can, sort of. For your fist couple of tanks your filter may pick up a lot more stuff and/or clog. This is because biodiesel is somewhat of a solvent too, and cleans stuff out of your tank and unfiltered lines.
Eats fuel lines - Not likely unless your truck is a lot older (92 or older) using natural rubber fuel lines and gaskets.

All you ever wanted to know about bio-diesel ---> http://en.wikipedia.org/wiki/Biodiesel

Hope this helps.

expect about a 10% drop in MPG and HP using %100 Bio. I am running about %20 in my 06 and can't tell any diff. except for the fact that it is quiet!

Better watch out. I just heard that Big Brother is watching again. I cannot say if it is true or not, but I heard that some people are getting hassled for using bio, because they are not paying road use tax to run it. Maybe just a rumor, but I would not want to get hit with tax evasion just for trying to save on fuel costs. What's next[verymad]

Thanks, got all my questions answered almost! I have a 3rd Gen (2006) 24valve, I'd assume from your reply it would be designated QSB5.9? I guess what I am asking is does the Cummins press release pertain to the 5.9 in my 2006 Ram?


DZLROKET: Not considering 100% Bio anytimesoon. Thanks for the headsup.
wurkenman: not making my own, buying from a commercial source. Still an issue in your mind?

Thanks again all! I wish I could give back but I am a 1st time diesel owner.

I am not sure what the Cummins designation is for the 03-06 engines. I think it might be the QS series But I am not for certain.

EDIT - looks I am wrong. The "Q" series is for agricultural and power generation applications, not automotive (read the 2nd link).

Awesome...thanks for all the help. I'm going to keep digging but my thoughts are its B5 for me in my new truck....because unlike my jeep I'm not quite ready to destroy this rig yet. And before folks reply that they've run B-whatever without issue I am NOT saying it can't be done. Just not for me right now.

-P

Even if all you put in is B5 you will still be helping your engine out. Biodiesel is such a good lubricant and with the ULSD everywhere it can't hurt to get a little help lubing up the parts.

When I bought my VP44 the technician I talked to said, biodiesel was a blessing for them as after people started using it, they started rebuilding a lot more VP44s.
I am not sure how true this is but I got a bit leery of bio after that. I add some 2 cycle oil instead of bio for lubrication.

Maybe due to a quality control problem on the BD manufactirier's part, or just an uninformed tech that had no idea what he was talking about.
I have nee running BD, in various mixes, for over 2 years and making my own for 2 years and have yet to even need to replace a fuel filter because of it.
