I am not familiar with this one but the nitrited Delo ELC seems to belong to the Cat ELC/ Rotella ELC family. You can check out its properties at this site
The nitrite-free Delo is the only one I have come across that is 2-EHA and nitite-free. Detroit Diesel PowerCool Plus (which I am told is the same as Old World Final Charge) is nitrite-free but is non 2-EHA.
Because it is 2-EHA, you have to be careful what you use it on. I am not aware of any engine manufacturer who calls for its unique properties. What engine do you plan to use it on?
