<human>: Could you distill the essence of the text into 1-3 sentences?

This literally is happening as we speak. I drive a diesel truck for a delivery company, and every now and then it needs a fluid called diesel exhaust fluid to be put in a SEPARATE TANK FROM THE GOD.

So this morning I get in the truck and it's telling me I need this fluid. So, in my infinite fucking wisdom, I unloaded the entire bottle into the gas tank. And not the DEF tank. Don't ask me how I made this mistake because I have no idea. I put gas in this thing every other day, you'd think I'd have the goddamn sense to realize that what I was doing was wrong. 

Anyway. So now I'm waiting on a guy to come tow my truck, flush the tank, and hopefully go about my day. My 14 hour day has suddenly just turned into a god knows how many hour day. The silver lining here is that thankfully I didn't try to start the truck. Then I'd truly be fucked. UGH.
<bot>: Put DEF fluid in my gas tank. Waiting for a tow and a flush. My day is fucked, and I may lose my job. Yay.
