Will DEF harm a CUT?

[Deepdrop]

I filled my cans at a station that apparently pumps regular diesel by default, but if you push the button, it pumps DEF. I was confused by this and put about half a gallon in my 5 gallon can. It's hard to get a clear answer by searching online so I thought I'd ask on here. Do you think it's safe to use this can that is 90$ diesel and 10% DEF on my Kioti CS2510?
Thanks for any help/advice.

NO DEF is extremely corrosive and will play havoc with the fuel system costing thousands of $ in repairs.

NO! Get rid of (how - I'm leaving that to you) that DEF. Flush the can (again - up to you how) and once dry, fill up with the proper fuel.

I have never had a diesel that required DEF, but a quick read shows it's BAD NEWS when mixed with diesel and run through an engine.
I'm really surprised that it would be pumped through the same dispensing hose just requiring a push button selection.
Definitely don't use the contaminated fuel in your machine.

Absolutely not. Dispose of properly and flush the can with about 1/2 gallon of clean diesel. Then refill. No not run DEF of any amount through the fuel system.
Hope this helps.

I wouldn't use that pump or station! Should be 2 separate nozzles and if station in area that goes below freezing, should be behind a heated door to keep the DEF from freezing in the nozzle! Run from that station!

I just looked it up DEF is 67.5% water!!! As everyone else said DO NOT USE!!! If you have a burn pile it would make a good starter!!!!!

Take it to a waste disposal site, do not run it in your tractor.

THANK YOU ALL! For saving me from a very expensive mistake. I agree that it is awfully odd to have one hose and a tank that dispenses DEF or regular diesel. I'm going to drive back and take pictures, which I'll post. I'll also talk to the store personnel to see if they can explain it to me. Thank you all again. I will follow up in a day or two.

I revisited the station. The manager was not there and nobody could give me any information. I'm attaching photos and a closeup of the instruction on the pump. There is only one hose, but it looks like the pump offers DEF and diesel. Two prices are on the pump as well. I tried pushing the DEF button and nothing happened, What do you all think?
