Supra LSD gear oil recommendation |
|
|
Just bought a 1984 Supra with a Limited Slip Differential. The owners
manual indicates that the gear oil should be API Service GL-5 lubricant for
limited slip differentials. I went around to the local auto supply shops
and none of the gear oil containers stated suitable for limited slip
differentials including the synthetic and semi-synthetic. The fellows at
the shop didn't know what the difference would be or if it was OK to use in
the LSD. I bought the semi-synthetic API Service GL-5 lubricant . Is this
OK for my differential? I checked some of the oil supplier websites (i.e.
Castrol) and there didn't appear to be a specific oil for LSD. Just their
regular gear oils said suitable for LSD.

Yes there is specific oil for LSD's and it should be easily available. Any
GL-5 rated oil is good for topping-up and it may say this on the can but use
the proper stuff when changing oil or you will have a very noisy and stiff
diff. The noise will likely be a 'graunching' type when hot and turning
tight. It does the clutch plates no good at all.

Castrol gear oil, or Castrol synthetic should work well. If you're
paraniod (like I am) then go to your local Ford dealer and get a jar of
Hypoid Gear Oil additive. It was $8 the last time I bought one 4 years
ago. You add about 2-3 oz. per GALLON, so I still have 1/2 the tube still
sitting on the shelf.
BTW, I have an '85 Celica GTS; basically the same car, but you get a
heavier front suspension, a different interior (slightly), the front facia
and rear deck, and, of course, the 5M-GE.
I also have an '88 Supra. They are definitely cool cars! Enjoy!
(Actually, YOUR Supra is probably more fun than mine! Mine is a heavy car
and isn't as 'flickable' as the '85 Celica...)

Do NOT use regular gear oil. Look harder for the LSD-compatible oil
that you need. |

I think the problem comes with people not knowing which LSD type they
have. Some are clutch types and some are worm-gear types, wont go into
too much detail as im not sure what yours is. But the worm types
(torsens) generally dont need LSD oil, whereas the clutch-type ones do?

A LSD is invariably a clutch type. All others are known by other names as
illustrated by you in brackets.
If it says in the bible that it needs LSD oil then it does. If it doesn't
then it don't.

:) Agreed. I wasnt contradicting the advice, i was just pointing out
the differences.
The supra is a close relative of the celica. My GT4's (alltrac) LSD is
torsen, thats the only connection i was making. |

Then you have emphatically not got a limited slip differential. What you
*have* got is a Torsen worm gear 'torque proportioning differential'. Your
use of 'LSD' to describe your differential is incorrect. There is nothing in
a Torsen that slips, even in a limited way.

Yes, but I'm sure that a '84 Supra does not have a Torsen. (My '98
Supra does, though...) |

The center differential in the All Trac Celicas that used to be sold in the |
U.S. had a viscous coupling for a center differential. The viscous coupling
uses a silicone fluid that is completely different and incompatible with
normal gear oil or LSD oil.

Oh but it is shit-for-brains. It is the limiting of power transfer to the
wheel with least torque demand by the use of clutch discs which slip in a
limited way. It is a description of the differential, not of its end result
in traction.

I wasnt talking about the centre diff which is indeed a viscous link.
I'm talking about the rear diff, of which the limited edition and some
UK versions had torsen LSDs.
