ZF Oil requirements

Pulling mine out is planned for next winter season. All she's getting this year is an oil change.

After checking for the safety wiring, an internal inspection and general detailing I'd really like to see about the possibility of either a 3:77(?) ring and pinion (muy expensivo) or changing my fifth gear ratio (not so expensivo?) to lower engine RPM's on the highway.

v8capri,

Go to the "Find" tab on the top of this page and search for ZF lubrication. This question has been beat to death in the last six months.

I must be doing it wrong, because I did this BEFORE posting and I only really found 1 item.
I just tried again with the term you said 'ZF Lubrication' and only got 2 posts.
So I don't quite know if 'beaten to death' is the right term.
Plus I have been an active member on this forum for the last 6 months, so would have seen it.

I always use a good synthetic 75w-85w gear lubricant in the ZF.

80/90 WT and change it once a year that is what I was told after RBT rebuild.

Capri try searching for "ZF Oil" that turned up a bunch of hits.
Here is one from last year.

Sound right to me. I always use a good synthetic 80-90 wt oil and change every year - two if I don't drive it much.

For more info search gear oil (make sure you uncheck "from this forum only" when searching) and you will see 10 pages of posts.

Is it true that the likelyhood of the ZF leaking is greatly increased by the use of synthetic fluid? (Or will it definitely leak?) I run Dino DNA in my ZF, so I don't know firsthand.

What will leak are the o ring on the rear cover.

You need to add either transmission stop leak which contains brake fluid or two tablespoonfulls of brake fluid. Now don't ask me Dot 3 or silicone , ok?

The brake fluid will swell the rubber o-rings and eventually dry up the leak.

It is common for the o-rings to leak with conventional lube as well so I don't think it is the synthetic to blame but I'm not going to argue about it.

I run the Redline Heavyshock, no leaks whatsoever with several thousand miles on the lube. But with the "thin" synthetic's I agree it will more than likely cause a leak.

I just found out my brother has this oil..... perfect
any idea how much these take ? so I can ask him to put some aside !

The ZF holds 7.50 U.S. pints or 3.54 liters "downunder" hope this helps Mate....
