#@$%! This is what Cummins told me about fuel additives:
"Thanks for your Email message. You have contacted Cummins, Inc. at our Customer Assistance Center located in Columbus, Indiana. This is our worldwide headquarters and has been our home since Clessie Cummins founded the company February 3, 1919.
There is no way for us to give you reassurance about aftermarket products. We have no idea what effects they will have on the engine. Espicially regarding additives we don't know what chemicals are in the additives and we don't know what happens when they burn. We neither approve nor condemn the use of any aftermarket product. Under normal circumstances we do not believe additives are necessary. Because your product is warranted by Dodge not Cummins it would be best to verify all these details with them.
Cummins designs and supplies the Cummins 6B5. 9 and ISB 24-Valve turbo diesel engines to DaimlerChrysler, however, DaimlerChrysler warrants the diesel engine and truck completely, as a package unit. Cummins, Inc. and authorized Service Providers cannot provide warranty coverage on Dodge Ram trucks powered with Cummins diesel engines, since all warranties are handled by the Dodge dealers.
To find the closest Dodge service, anywhere in North America, call Chrysler at 800-992-1997.
For assistance with Dodge Ram truck issues, Dodge requires a Vehicle Identification Number (VIN) for vehicle identification (i. e. , model, year, build plant, etc. ). Always have your VIN number available when requesting assistance with your Dodge vehicle.
When bringing a Dodge truck to a Dodge dealer for warranty service, you may also wish to verify that the service department is availing themselves of the diesel technician troubleshooting assistance that is available to Dodge dealers by way of their S. T. A. R. Hotline. Dodge dealers may call the DaimlerChrysler Hotline for technical assistance.
Prior to 2004 model year, Dodge warranty on the engine was 5 years or 100,000 miles, whichever comes first. The warranty coverage for the Cummins Turbo Diesel in the 2004 model year Dodge Ram is 7 years or 100,000 miles, whichever comes first, and is handled by Dodge dealers, not Cummins. See your local Dodge dealer or
Official Dodge Site - New Autos, Trucks, Minivans, SUVs, Cars, Wagons <http://www.dodge.com> for further details regarding this warranty coverage.
Customers should call Dodge Customer Service Hotline (800-992-1997) for assistance.
We thank you for your interest in Cummins products. We occasionally misunderstand a question. If our answer to your communication looks like we have misunderstood your e-mail please reply with further inquiry. "
