DEF Availability
We will leave Ohio soon ... on our way to Alaska! Is Diesel Exhaust Fluid (DEF) readily available along the Alaska Highway and in Alaska?

I buy mine at NAPA. Around here when I catch it on sale, it is in the $11 a jug range. Last summer in Gunnison Colorado I paid about $25 for a case of two jugs. Our Wal Mart also sells DEF in the motor oil section.
