Took 3 oz. sample of my hydraulic oil with 462.8 hrs. on oil today to send to Blackstone Lab for analysis. My hydraulic oil was changed at 85 hrs. and again at 610 hrs. I used Mobile 1 15W-50 Advanced Full Synthetic Motor Oil.
Paragraph below is copy and paste from my owners manual. I don't know where I got the idea that I should use Mobil 1 15W-50 synthetic oil.
Fluid level should be 1" (25.4 mm) from top of reservoir.
Use only 15W50 synthetic oil or 20W50 synthetic oil. Hustler®
Full Synthetic 20W50 Hydrostatic Transmission Oil is recommended.
Should I be using an oil that is stated on the bottle Hydrostatic Transmission Oil as seen in pic below?
