new here to the fourm, been following for a while and have seen lots of good input.
I have been using Rotella T5 0w40 synthetic oil snce ii bought the truck (2 years) been changing it regularly without any issues. I changed it a few days ago but instead of using Rotella i used Liqui moly 0w40 synthetic. since then when the truck is cold it runs rough like a injector sticking. Starts perfect and runs perfect when warmed up but untill then it missis pretty bad.I never had this issue before i changed the oil, also on a cold start i have blue smoke which i never had before this. Do you think it could be the different oil causing this or just fluked into a injector going bad at the same time.
