unimogjohn Posted September 29, 2010 Share Posted September 29, 2010 In the teens and 20s cars, most of us are running straight 30 weight, non-detergent oil in the engine; 600 weight steam oil in the transmission (your local Ford Model T/A vendor should have this weight); and regular 90 weight gear oil in the rear axle. In the steering box most oil will run out, so many are using just wheel bearing grease pumped in with your grease gun. Use the 30 weight motor oil in your fan hub too. Hope this helps.
