Gadget Guru: What you need to know about DEF

NORTH PALM BEACH, Fla. — For people who own a newer diesel-powered motorhome, there’s a good chance it requires diesel exhaust fluid (DEF). But what is DEF and what’s the rule of thumb on how to use it? Gadget Guru Andy Pargh asked on his blog.

What do you look for when purchasing DEF? What’s the shelf life on DEF and what considerations should be made for storage? What preparations should you make prior to pouring DEF into your motorhome? Those questions and more are addressed in a YouTube video.

While some motorhomes have DEF filler necks on both sides of the coach that allow us to fill at most truck stops, some of us are not that fortunate and have the filler only on one side.
