If it is the standard diff they are not sealed FG just uses grease. , you can put in diff oil easily by pulling out one axle and putting the model on its side and fill the diff. then re install the axle. You will have to continue refilling it because after a tank or 2 it will spit it all out. I have tried 120k. Works good. I have a LSD 4 plate now.

Have you considered FG's diffgrease(siliconegrease)? Part # FG 6512, i have been told that this gives you about 65% diff locking when you use all the grease in the bottle.

When using silicone oil,regardless the steel sleeve and/or use of silicone sealant,the diff will leak like crazy because the diff's body is plastic and it tends to bend resulting a break on sealant [8D]
FG 6512 grease,is the ONLY recommendation for stock diff lubrication.Use a max of 35 ml.Anything more than that will lock the diff a better way(wich is what u want)BUT the body might break.The sleeve that enters the ball bearing on either side,snaps like a toothpick due to the forces applied(hydraulic pressure,body bending).It happened to me[]
Make yourself a favor and,
a: Get a completely sealed diff,eg a viscous from FG to keep your expectations high(pricey[:@])
b: Get the aluminum upgrade kit(aluminum body,sleeve and O-rings)

If money is no big issue, do as i did and buy the [link=http://www.rc-car-online-shop.de/cgi-bin/cosmoshop/lshop.cgi?action=showdetail&wkid=24622&ls=e&nc=1275850947-24855&rubnum=&artnum=fg_8485_05&file=&gesamt_zeilen=0Tsuche8485/05]8485/05-kit[/link] (i already had the alloyhousing and some other parts so i just supplied the rest), this will save you A LOT of mess with the silicone grease being everywhere and on everything you touch after you are finished working with the diff. It takes you a few seconds to adjust the locking effect on the diff, and you can do it without dismantling the whole rear end of the car.
