LIMITED SLIP DIFFERENTIAL OIL – 1972 CHARGER R/T

[Jivan Naran]

Hi guys

Is it safe to use any 80W-90 gear oil in a limited slip differential? Some brands say you can and others don’t state at all. I’ve heard of some people putting in limited slip additives also. It would be great to get your opinion. Thank you

80w90 is just fine in that car but i would definately use a limited slip additive with it.

80W-90 is fine in your diff, but you must use the additive. It is a friction modifier that allows your axle clutches to slip during cornering. If you don’t use it, the car wont turn in slippery conditions like heavy rain. After a fluid change, I always drive the vehicle in a few figure 8 patterns to make sure the stuff gets worked into the clutches well.

The LS diff oil will be fine.

If the oil says it is meant for LSDs you can put it in you don’t need any additives but if it says nothing about LSDs don’t put it in you shouldn’t need additives if you use the right oil
