T-3 vs t-4 oil

[the missing link]

Can you give a n14 the oil additive ( gear oil) if yes ,ok , if no why . Just curious I have a rebuilt n14 at home , thinking of putting her to work this summer . I would also very curious if any body has played with them or if there is any gains to be made by it . I know they are not a isx and a far cry from it on the ECM side . say what you want but they are a damn good motor. I am not saying they are as efficient as the isx pulling lighter freight , but with 140000 lbs or in the oil patch , a different story I think .
Although I don't know f@ck all and the first to admitted to it .
Just trying to learn and understand.


Ps I wish someone would make a kit for the Vgt turbo for one :big_smile2: hehe
