Well, I purchased 15 gallons of oil from Tractor Supply. Their Travelers brand 10W30 was the best price I could find. I put 10 gallons in the tank and started the engine. No blowouts so that's a good sign, however, I found a steering motor hose fitting leaking. I noticed it was a little odd feeling when I was assembling it. Not a crossthread but a little stiff anyways. I'll have a new hose assembly and a motor fitting made up next week. I also noticed leakage around one of the spool valves on the front cylinder control valves. I'll clean and paint my spare control assembly and see how it does before I rebuild either one. When I get these two leaks fixed, it will be a dry machine. Wouldn't that be something? A hydraulic machine that doesn't leave a trail,,,,,,,,,
