Hope this is OK for this forum - DEF question
For those of you with diesels in your truck, have you found a good fill spout for the 2.5 gallon jugs of DEF? I have tried two of the ones furnished with the DEF and both leaked. I tried tightening ...

I have found that EVERY SINGLE jug of the stuff I've bought in a year has the spout threaded in a way that the rubber vent is at the bottom and causes leaking like you explained. EVERY ONE. I have unscrewed and screwed them so many times thinking I was doing something wrong. Nope. The way they are manufactured the vent ends up in the wrong place. The only way I found to deal with it is hold the bottle upside down in the most awkward way possible.
