Got a notice from the National Biodiesel Board today that Cummins has now approved 20% biodiesel blends for most of their engines on 3/21/07. Here's a link to the details from Cummins:

I think up until this announcement only B5 was approved?

Ryan :cool:

What Cummins engines can be used with B20 biodiesel?


The current approved engine models are as follows: On-Highway: ISX, ISM, ISL, ISC and ISB engines certified to EPA '02 and later emissions standards, and ISL, ISC and ISB engines certified to Euro III
 
It is all in the wording... . Be careful



It sounds good but read the specifics. It must meet specifications, but guess what, the B20 specs haven't been published yet.



Also:

Please consult DaimlerChrysler for specific requirements and approved vehicle models.





Cummins may cover problems but you must "consult" DC.

Rams are a DC product.
 
I think we'd have a hard time buying commercially available B100 that doesn't meet fuel industry specs.

Sure DC doesn't have to warranty it, but it lets a few guys who want to try it know that they're OK.
 
yeah, and '01 and earlier are out in the cold. Likely the difference in injection pumps. Sucks for me.



Most of us that have trucks of that age have no warranty left on any fuel system parts so you are welcome to do whatever you want. There are an awful lot of people out there running it and having no trouble(myself included).

Exactly! The fact that it was approved for '02 and above, which might be under warrenty, says a lot. No way Cummins would have put their stamp of approval on a fuel if it didn't hold up under testing.

Whoa! Bio is fine for P7100 equipped trucks! I've run B100 from a local distributor and it loved it. B20 ought to be OK in just about anything.
 
I know my Cummins loves B100. I have a very good supplier and the fuel meets all specs that #2 does, they even test every third batch to be sure. Now that things are warming up here I am going back to B100, I run B20 in the cooler months to avoid gelling issues. After adjusting the valve lash and running B100 my truck is almost as quiet as a 3rd gen, almost. If you can get a good supplier bio is a great thing.
 
Cummins has approved b20,Dodge has not. There may be some retro-fit kits coming in the near future. Possibly different filtration,maybe changing fuel supply pressures,and software changes.

12. Is B20 approved for the Dodge Ram Turbo Diesel?



For Cummins engines in Dodge Ram trucks, biodiesel fuel can be blended with an acceptable diesel fuel up to a 20 percent volume concentration (B20) for municipal, government and commercial fleets only. This applies to selected model year vehicles. Please consult DaimlerChrysler for specific requirements and approved vehicle models.



Hummmmm, maybe yes, maybe no :-{}

As if those trucks are any different than the trucks they sell to consumers. Whatever. :D
 
I am currently running B20 only because it was too cold to go any higher the last time I filled my tank... 550 gallon tank that is. I'm due to get filled by the end of this week. I haven't decided how high to go yet, a lot of that will depend on price. Last summer I ran a bunch of B80 w/o any noticeable effects. I'm sure I'll go at least 50% this time. The fuel guy just brings out however much bio I tell him to and tops it off with #2 to make whatever mix I want.
 
I'm currently running B10 ULSD. I'm a little worried about the combination of bio and ULSD. Doing some research on that now...

The guys that run T-Gill Fuels in P'cola have been runnin' B100 in their 6. 0 P'stroke for well over a year now with no ill effects. I wouldn't fret about runnin' B20 in any new diesel.
