01 cummins/no power when cold
#2
How cold is it where youre at? Cummins will be a little sluggish until it warms up. You might try a thinner oil in the winter. I run Rotella t6 5w40. I also plug my block heater in and have the outlet on a timer to start heating it up a couple hours before I leave for work. If its an auto its probably time to change fluid and filter.
