There’s nothing special about the CASE hydraulic system. Gear pump, manual shift valve, and a G-rotor. If the oil isn’t full of water or particulate contamination it will run fine. Car engine oil has more additives than hydraulic oil; like detergents, it should be more expensive but isn’t because of sales volume and consumer pressure. If the tractor will run in cold weather, ATF is better as it has a better viscosity index. Synthetic is better still. You can tell the difference when cranking in winter conditions. I use AW46 hydraulic oil in all my CASE tractors because I get it for free, but I buy ATF for the tractors with hydrastats so they don’t cavitation in cold weather.
