We have packaged together 12 quarts of Royal Purple's Duralec Ultra (04154) 15W40 motor oil with 1 Royal Purple Extended life oil filter for an easy one click oil change for your 1989 to Current Dodge Ram with the 5.9 or the Newest 6.7 Cummins diesel engine. I have included some info below for you to read about the High Performance Ci4+ Rated Commercial Grade oil from Royal Purple. For those that don't know, this oil provides all of the Phosphorous and Zinc that have been removed from the SAE certified oil. This will give your engine the protection that it needs and will protect your expensive engine better than SAE Rated oils. Running an aftermarket cam? Most manufacturers are going to recommend some type of Zinc additive to protect that new camshaft. Royal Purple Duralec Ultra already has you covered without having to buy additive!! Give us a call with any questions. We also carry the full line of Royal Purple!!
