Re: Winter Operation
You are getting down to the lower end of recommended temperature for 15W30. There is a chart in your diesel supplement. You should probably check for a bad glow plug or two first. See the Hard Start/No Start Sticky. Then change to a 10W30 oil for the winter. Your truck will be happier with it.
