My Chilton reference material say to use a 90W for Farenheit -10 to +32.

I have 140W EP (Extreme Pressure) in the differntial. EP is the only type of gear oil you can put into the differrential. The nature of the gears are slidding teeth. Good replacements for these Roadster are getting harder to find over time, so make it last.
Fill 1/4 inch below the fill hole on level ground of course. Overfill will blow the oil out onto to the brake shoes at high speed ruining the shoe and cause bad stopping.
