I know there has been discussions about the oil filters on the 98 and newer trucks. Seems if they are the regular 'Fram' type, cellulose filter you can run into dissolving problems. I've been using the Cummins filter, getting them from the Cummins dealer, at about 9. 00 each. I now get a discount at the Dodge dealers that will make the cost of the filter about a dollar cheaper,, plus it's closer. Does anyone know if the 'Dodge' filter is the same 'stratopore' we're supposed to use,, according to Cummins? One would assume the dodge filters would be the same, wouldn't one?? Thanks for your help,, Oh TDR Gurus... . Neil
