Transfer case: Lucas?

Hello. I changed fluid there over 3 years ago, as I began noticing whining noise. Put in Pentosin ATF1, noise kinda went away. Now, the truck had 197k on it, the noise is back. It'd not horrible, but I hear it. I am thinking, perhaps I should use a Lucas product? If so, which one? Anybody went down that road? I know T-case is not immortal, but I want to sqwease abother 20-30K out of it.
​​​​​​​Thanks

Petosin was never on the list.

Transfer case

Pentosin was never on the list, but people do use it. It exceeds 236.10 requirements, it has 236.11 according to manufacturer. Nowdays people use newer MB 236.12, with mixed results. As I stated, my T-case started to make noise almost 4 (four) years ago, BEFOURE I put in pentosin. At that time, I had about 160K on the truck. Now, since I am hearing noise AGAIN, the truck had 197K on it. This alone exceeds life expectancy of the transfer-case, as far as I have heard. My question was NOT about Pentosin, but rather, about Lucas.
Thanks

If you used the proper fluid the first time, Lucas wouldn't be necessary to think about.
