Its time to change the oils in my Transfer case and diffs. Anyone got a recommendation on using LOS with the gear oil? I noticed someone recommending 50% in tcase and 33% in diffs.   thom mathie (Muskyman) Senior Member Username: Muskyman Post Number: 634 Registered: 11-2002 Posted on Monday, March 01, 2004 - 12:38 am:    I run it in both diffs and TC and it does alot to keeping them quiet.   Brian (Bthaxton) Member Username: Bthaxton Post Number: 84 Registered: 02-2003 Posted on Monday, March 01, 2004 - 06:10 pm:    Is that the correct percentage? I might try it. My '97 D1 has 110K miles, but I am having no problems. Just thought it might be preventative.   eric johnson (Eric2) Senior Member Username: Eric2 Post Number: 291 Registered: 05-2003 Posted on Monday, March 01, 2004 - 06:20 pm:    That was 50% in a '62 SERIES IIA transfer case- not a DISCO SERIES II. Don't you use ATF, in a Disco transfercase? I would use synthetics were possible. You'll get better milage if you use them in the diff's.   Kristopher March (Apexdisco) Senior Member Username: Apexdisco Post Number: 324 Registered: 02-2002 Posted on Monday, March 01, 2004 - 06:38 pm:    I put 90wt gear oil in my transfer box. 99 Disco Series I. Also put that in my diffs and I used synthetic. I'm going to try some LOS next time I renew the fluids. ATF goes in the transmission gearbox.

Dexron III trans fluid in the automatic transmission.   Ken Rountree (Krountre) New Member Username: Krountre Post Number: 16 Registered: 01-2004 Posted on Monday, March 01, 2004 - 09:09 pm:    You're right Eric, that was in a Series IIA. I was wondering if anyone ran that ratio in a disco. ATF goes in the transmission; GL5 in the tcase in my 98 DI. Since it came up, is LOS and synthetic gear oil redundant or useful?   Jeff Mclaird (Granitedisco) Member Username: Granitedisco Post Number: 248 Registered: 08-2003 Posted on Monday, March 01, 2004 - 09:34 pm:    Probably a stupid question - but is this the same as diff additive that alot of people put in for Limited Slip Diffs ?

That's what I used...   Robert Sublett (Rubisco98) Senior Member Username: Rubisco98 Post Number: 1160 Registered: 04-2002 Posted on Tuesday, March 02, 2004 - 07:44 am:    I've used 100% Lucas oil stabilizer in my diffs and swivels for quite some time on my D1. My wife's D2 acquired a leaky seal on the rear hub, I swapped it out with LOS and no more leaks there either. I like that stuff..
