Ok guys so I'm looking at buying my first duramax. I was going to a while back but decided to hold off. So my wife is giving me a hard time about buying a diesel. Her brother in law says his is a nightmare in the winter. We live in Vermont. He said his gels up a lot. So I was wondering what you guys are using in your trucks to avoid this problem. I'm sorry if this topic has been covered but I'm new to forums.
