Topic: 1936 gear oil

  What do you recommend to use in the rear end and transmission?
The service bulletins say:
Transmission above freezing s.a.e 160, below 110
Rear end above freezing s.a.e 160, below 90 or 110..
Is there some modern oil that that works well for year round, not that I drive it below freezing.
Thanks
Tom

  For the rear axle and transmission I would use a modern High Performance Gear Oil such as Valvoline SAE 80W-90 API Services: GL-5, MT-1. You can leave this oil in the transmission and rear axle year round.

  What would you think of Citgo Mystik JT-7
API GL-2 through GL-5 and MT-1 ?
Thanks for your help.
It is SAE 85W-140.

  carcrazy gave you very good advice. Your name-brand preference will be fine - he likes Valvoline, well, so do I btw for the '47, but choose your name-brand and go with it.

Since I live in central-humid-as-heck 95-100 degree summer NC I do run 85W-140 in the rear during summer months but only change to this if going on a long (100+ mile one-way) cruise, otherwise run 80W-90 in both for year-round putzin' around town.
