[chris d]

the past couple of weeks when i start my truck in the morning it starts then shuts off once it turns on it does this around 5 times till finally it stays running. once it stays running the rest of the day it will start right up no problems anyone know what it could be?

Try switching to 5w40. A lot of people like Rotella t6
