differential fluid?what kind?
 

Hopefully the Weather is going to Cooperate.I would like to Install my N/A LSD.I would like suggestions on the Type of Fluid to use in the LSD(it's an 86).I'm leaning Towards synthetic.Brandname,Cost and where to get it in/around Ottawa.Thank you gentlemen,In advance.As always I value your input.

Redline 75w90. don't know where you would get that around Ottawa though (it's around somewhere).

Partsource also has Lucas Oils gear oil that is appropriate for LSD.

I'm using Royal Purple 75W90 Lordco caries it. I think napa does too, but I'm not sure. Lordco also carries redline.

p.s. are there any lordco stores on the east coast? I know there were a few napa stores, but can't remember lordco.
