Duramax running rough
1969 kenworth cabover
My dad has been running Rotella in his 2001 duramax since it was new.... he changes it every 5-6k miles and has 319k miles on the truck and it has never been rebuilt. my Brother also uses Rotella in his 2008 duramax that has 110k miles on it with no problems.
