can i put water in my def tank?

On 95 yes...however, from long island: unless he takes a local road onto manhattan then takes a tunnel outbound...there will indeed be a toll. (and likely a ticket for a rookie, over 55' overall length on manhattan during prohibited hours, being on manhattan without a destination or pickup on that island: pick one they are both expensive lol)

 

Def has a shelf life. So if one does this you would need to change out that jug with a new one every now and then

I carry 2 extra boxes/jugs just in case...a little trick I learned from my co driver when I was driving for Werner

 

I heard this today. Thought it was a "drivers story"
but they said that the govt finally found a way to sell urine to us. That def is basically urine. And that its really better to pee in the def tank. Than use the weaker urine known as def.
no idea if there is a bit of truth in that at all. I have no expirence with truck that requires it.

 

It's false. I know there's a story about it, it's not the same solution. DEF is a purified state of urine. Going the direct way is not advisable

Yeah, I was kidding.

 

I know you were, but it's been talked about several times on here

 

Lol I'll have to take your word on that. Like I said when I heard it I thought right away. "right" lol

 

Only expire nice I had is when my buddy bought his '12 f350. Ran out of DEF and we all took a leak in the tank. Didn't help any, the computer recognized the mix as "non-compliant". Ford said you'll get he same reading if you use old def, it'll have a negative effect. Anyway, ford gave him two choices, pay $2k for a new def tank, labor, and new hoses or the ford dealer will pay for it and void his warranty after.

He now has an H&S tuner with the dpf and def deactivated and straight piped it. Lol
