Hi guys (and gals)
For first, and one time, sorry for my gruesome English. Its less my fault, rather of the education system... But I give always my best. Hope this works good enough (dont call me Yoda please )
Ok. Now my question, corresponding to thread subject.
(I have WELL search for it, but NOT FOUND threads with clear answers to my question. Sorry.)
LimitedSlip (LS) adds and LSD gear oils. Technical functionality of LS supplements.
I dont understand this, WHEN I ponder above
The necessity is clear, usage is clear and design of a few types of diffs is also comprehensible. Ok, what I have dont understand:
If you need LS adds in diff oil, and you dont have it, you have: chatter or humming and so forth, from the LS part of LSD. Ok, clear matter.
FOR ME (so far), this means, the diff locking to soon and/or to much. You also need LS adds in the oil, but it be called: limited slip.
If you have for example humming ,you have (for me, but I am still not enlightened) too little slip. LSD lock to soon/to hard. Or not?
Mean, LS adds, as friction modifier, not limited but increase the "slipness" of the diff oil?? Or I bark the wrong three?
As already stated, this make me confused.
Background.
I have still a little bottle of OLD and "legendary" (?) Sturaco 7098 diff/gear additive. And If "you" look on the site for newer Sturaco, 7098, they say:
" Sturaco 7098 is a friction modifier to supplement sulfur-phosphorous gear oil additives for limited-slip performance"
And on the another hand, for:
"Manual transaxles: 3% - 5%, Engine oil for noise reduction: 1 % - 2%, Universal tractor fluids: 2% - 4%"
Nothing about LSD. And I known, also ZF (german gear company) use 7098 as "FM 1992 KS", as additive. Officially. In automatic transmissions…

But, I have no LS diff and no ZF gear parts. I have manual transmission, angle gear and no-LS diff. I only thought, I can increase efficiency of my gears for 0.0x%
if I add 1% Sturaco.
But-2, you MAY use 1% Sturaco 7098 in engine oils, but never ever for example… Penrite Limslip Additive
With the same specs like Sturaco
