Autozone oil for LSD?

[funcrew]

Is there any civilian-grade Autozone/ORiley's diff oil that will work OK in an E30 LSD? I really don't want to take the time and cost to order racing-grade oil by mail for my daily driver.

Any input is appreciated.

Any quality 75w90 gear lube with friction modifiers will work fine.

OK, but how can you tell on bubba-grade gear oil whether it has friction modifier? I know firsthand how grabby the diff gets when you run non-friction-modifier oil.

You can get the modifier in a squeeze bottle, add as much as you like

It will say something about being for an LSD on the bottle

I added 4 tubes of modifier and now my car only goes backwards

Royal Purple is overpriced and not all that special. But the internet sayz itz good!!!111111

Seriously Tim, any cheap 75w90 or 80w90 will be just fine.

I have Royal Purple in one LSD and Lucas in the other. I wouldn't buy Royal Purple again just because of the price.

i agree royal purple is over priced just go with any 75-90

and i'm assuming this applies to any getrag?

or should different ones take different tranny fluids?


The reason I ask is because we're gonna try and have a tranny day on three e30s and we're thinking of just buying a big jug to save money.

valvoline actually makes good stuff..a bottle or two of that and some lock up fluid and youll be fine. thats what i run.

Well, this thread is about differentials BUT most Getrag transmissions take 75w90 gear oil too. There are some that take ATF and will have a green label on them saying so.
