Use in my 2004.5 Dodge 3500 HD 4X4 CUMMINS 24V. I have used this oil for 19 years. My truck has 5168962 now and still pulling away. I change every 5000 miles.Was inside motor for injectors and seal,looked like new. Royal Purple lives up to its reputation and my truck is proof. Oil is slick and really sticks to parts like a synthetic oil is designed to do. Would recomend over Rotella any day. ### ⭐⭐⭐⭐⭐ Great Oil! *by on Reviewed in the United States January 2, 2026* Using this oil make my duramax engine sound better than ever.
