I had a 2012 ram 3500 and sold it 2 years ago. I always ran valvoline premium blue. From FCA I see they are in bed with Shell and we should run rotella but Cummins appears to still align with Valvoline. I never had issues with valvoline and it’s cheaper than rotella.
I now have a 2021 6.7. What do you guys think about me running Valvoline 10w30 during the Nov-March time and then valvoline 5w40 During the warmer months? I’m in the Dallas area. I know what the manual says - I could run 10w30 year around.
I plan to keep this truck for 10 years.
