1975 Cushman Differential Oil??? Which type?

defiant1 · 05-21-2016, 07:11 AM

Good morning party people. My first post and since I did not see a sub-forum for Cushman, I am inserting my inquiry here.

I have a 1975 Cushman Golfster, 36V. I have little to no information on this electric cart as far as the specifications of the vehicle, one of which is the differential oil. I would like to replace the lube, but am unclear on which viscosity to utilize.

Thank you for any advice or practical experience.

To the top. Needing to rectify this issue. If there is another forum out there that may be of better assistance, please let me know.

Good to know, I have read over a hundred threads discussing how 30W motor oil should be used vs. 80W-90. For the older carts, I wasn't sure what was acceptable.

Hi,
I'm wondering what you decided to go with. I'm in the same boat in my Taylor Dunn cart. Manual says 20 weight oil. I can't find that anywhere. I guess 30w motor oil is probably what I will use.

I wound up using the same lube I put in the lower unit of my boat's outboard motor (80w90). No issues so far.

Thanks for the info.

I'm going to use 90 weight gear lube. I think I've been overthinking this one.
