Just went to 5W40 Rotella
I had a cold start problem and I read a TSB that stated that the heavier 15w40 was causing trouble. I started the truck this morning and started great with the 5W40 at 25 degrees. My question is will there be any problems running the lighter oil and should it be run in warm weather or just switch back to the 15W40? I will have a better test when the weather drops down in the teens. Atleast it is running on all the injectors when it first starts. This oil should be good and do something at over $16.00 a gal HA!!
Anyone having the same trouble or ideas?
