Coolant type

Seems everyone says to get coolant that is cat ec-1 rated, but most guys seem to run the delo ELC. Why not run the cat. Is it ok for the 6.0 or is the Delo better
Thanks in advance

You can run any ELC that is CAT-1 approved. I think I ran the cat stuff? Either that or Shell. I forget what went into mine.

I went to napa and got Zerex Cat-1 rated ELC..

My local Kenworth dealership told me every coolant is exactly the same except for the color. Its made in the same plant and then sold with different labels. Haha. I didn't buy anything from them, I went to the CAT dealer. I can see a difference in the CAT concentrate vs other brands. It almost looks thicker.
