I know that Cummins say's we can use a 5% blend of bio in our trucks, and 20% in fleet trucks, and still be covered under warranty. But I read this article on www.dieselworldmag.com. It say's, "Last March, Cummins announced the approval of biodiesel B20 blends for use in its 2002 and later emissions-compliant ISX,ISM,ISL,ISC and ISB engines. This includes the recently released 2007 products.

The article goes on some more about why the upgraded the use of bio. So does this mean that we can now use B20 blend in a NON fleet truck and still be covered under warranty?

 

The actual article from Cummins does not appear to include the ISB engine:

The way it has been explained to me is that if Cummins warrants your engine then yes you would be covered. ... but unfortunately, Dodge warrants the engines inthe Dodge Ram notCummins.

DC only approve the B5; B20 for fleet vehicles. (Whatever constitutes a fleet vehicle.)

 

Oh, I see how it works now. Well, that's a bummer.

 

Cummins has a FAQ that says the ISB is approved for B20.

The Cummins FAQ does say it's approved for the ISB engines, that's what we have.

I stand corrected

 

I've been running B20 in my 01 for 6 months with no issues.

 

Yeah, but it doesn't change anything because Dodge warrants our engines. Alot of folks use B20 and even some use B100 without any problems. If fuel related issues do come up, Dodge is quick topoint towardsthe biodiesel from what I understand. (But, I think they send an DC expert to verify high dollar claims to the dealership or put it under more scrutiny.)
