Hello there! Never thought I would say it, but I just bought a Dodge! Never had anything against the brand, just always owned Ford/Chevy. I have to say, I knew I was buying the truck as soon as I sat in it and started it up. What a nice ride, drives awesome(the 82 miles I have put on it) and rides smooth. First experience with DEF, 82 chevy was the last diesel I owned and that was years ago. Anything besides not running it out of fuel and keeping the DEF topped off anyone can suggest to stay on top if for these new diesels? Thanks in advance.
