Will DEF harm a CUT?

[Topzide]

Instructions say to open DEF nozzle door then press the yellow DEF button to dispense it.

I thought that was the case as you couldn't possibly have 1 nozzle for both! DEF in diesel is bad! Diesel in DEF is bad!

 

[Topzide]

You didn't get anything mixed with your diesel that you dispensed.

Agree looks like dispenses both but on all the DEF equipment that I have been around the DEF nozzle is smaller in diameter.

If dispenses both through same nozzle I would buy my diesel elsewhere.

If the pump looks like this the DEF hose is separate.

I see what you're saying. I misinterpreted the instructions and thought that just pressing the yellow button resulted in DEF being dispensed. Now that I know what DEF is, it makes sense that there is another nozzle, although I don't see where the "nozzle access door is". But it must be there somewhere with a separate hose that dispenses DEF, and you are correct that I did not get any of it.
Thank you very much for your explanation. I feel much better about this.

Gotta admit, just seeing the pics as presented, those are a little confusing.

Also, why would you mix On Road with Off Road? Kinda defeats the purpose, no?

Aqueous solutions and Diesel won't mix well. If you had it in a glass container you would see the line for water (which should be heavier than diesel and on the bottom), and the diesel above. It wouldn't take much to separate the two.

If you just pour a little into a jar, you will get whatever comes out of your can first. If you shake it up before pouring into the jar, it may turn cloudy, then separate over time.

If you have any doubts, then do some tests before using the diesel.

Now that we know NOT to use DEF in our tractors, what IS it used for?

Seen containers sold at stations. Never knew the purpose.

Some tractors and pretty much every truck sold in the last 10 years do require def. But it doesn’t mix with the fuel ever on any machine. There’s a separate tank with a blue cap for def. Mixing def with the fuel will result in the absolute best case scenario the engine stalling out on the water. Catastrophic damage to the fuel system is likely.
