Just put some DEF in the tank for the first time. I used the jug that is available everywhere. It didn't take the whole 2 1/2 gallons and splashed out as in overfill. Do I need to siphon some back out or am I going to be ok?

Your fine, best thing to do is wait till 1/2 a tank on the def and then it will take a full jug

Thank you. My gauge dropped to 3/4 tank 500 miles ago and hasn't budged. After overfilling it, it still reads 3/4 tank. Why did RAM even bother putting a gauge in? Read several posts that said it would go many miles at 3/4 tank, then drop like an anvil to 1/4 tank. Go figger.

Mine has always been pretty accurate but recently i was at 1/4 tank i put a jug in and it stayed at 1/4 so im guessing i have some frozen def at the top of the tank

Yeh, hasn't been cold enough here to freeze anything lately. And when it does freeze, it only goes down to maybe.....29 for a night.
