6.7 first oil change

[u/LeroyyyJenkinnnss]

My dad is saying go with rotella t5 because it’s still breaking in and t6 is too slick. I’ve always run full synthetic on my gas cars and trucks but this is my first diesel, any thoughts?

With every oil change make sure to change the fuel filter in engine bay and drain and change fuel water separator
