Middle of a fluids flush

[BROOMY]

In the middle of a all fluid change on the E30.
The problem is this my diff fluid or fluid for another diff

[BROOMY]

Nobody?

[BenHar]

LSD or open?

Open I think.
But who knows on the order form there was no optional LSD ordered.
There was no tag on the diff anymore but coulda came off so I'm treating it like a open.
Anyway that bottles not enough . Oh no that's engine oil I'm reading.

With no idea what diff you have, or even what E30 you have, then no-one here can offer you any meaningful advice.

[BROOMY]

As already stated in another thread m42 engine so an IS.

[Grrrmachine]

Then you should have a 4.10 open diff. 80W90 should be fine.

Jack the car up so that both rear wheels are off the ground.

Release the hand brake and put the gearbox in neutral.

Turn one of the rear wheels. If the other wheel turns in the same direction then it is an LSD. If the other wheel turns in the opposite direction it is an open diff.

In either case the oil in your picture is incorrect.

From http://www.e30zone.net/e30zonewiki/inde ... fferential (which I linked to above):

"For normal, open differentials, use a 75W-90 oil, such as Silkolene Syn 5, Redline 75W-90 NS, Castrol SAF-XO or Fuchs Sintopoid. You will need approximately 0.9L for a small case differential, or 1.7 litres for the larger (medium case) diff.

For Limited-Slip differentials, use a 75W-140 specifically designed for plate-type LSDs. A normal gear oil will destroy the plates and make it work like an open diff. The recommended options are Castrol racing b373 or Syntrax limited slip (which replaces the old SAF-XJ oil) "

Would you like one of us to come round and do it for you?

The specified oil (for an open diff.) is a straight 90EP, which you'll struggle to find nowadays. The EPX 80W-90 will be fine, as will any of the oils in the wiki article..

Something I've been meaning to ask you though. Just been curious...

Is your name really Ben?

[hennared323i]

Demlots other half I've always thought.

No idea why other than the similarity of tone/sincerely

Ewords are so hard to figure out at times

Op, follow the wiki guide

[BenHar]
