I follow the manual i got with my machine and use 10-30 oil for both hyd. and engine.I personally run 20W50 engine oil, cheap and works just fine. You can't use oil that is too thin.
If its under warranty you must use genuine bobcat oil.
I'm not sure just how much thicker 20W50 would be vs 10W30 in below freezing temperstures... I just use it because when its on sale, its really cheap over here.I follow the manual i got with my machine and use 10-30 oil for both hyd. and engine.
Would 20w50 work in temperatures way below freezing?
For hydraulic oil, I use only the Bobcat stuff. I know lots of folks don't, and that's fine. Just offering my perspective here. My reasoning is that I only have to change the hydro oil every 1000 hrs. It costs more, but at last check it's about $20/gallon vs $9/gallon for motor oil. $11/gallon more x 8 gallons is a hundred bucks. 1000 hrs on my machine is about 5 years. So for 20 bucks a year I use the real stuff. But I really respect the opinions of Tazza and others who use engine oil. I just look at it slightly differently. ---RCI'm not sure just how much thicker 20W50 would be vs 10W30 in below freezing temperstures...

I looked around and the upper end for ISO 46 hydraulic fluid was 80F. And that is what I believe Bobcat hydraulic fluid is. But even in NY it can get into the 90s in July and August.I,m with bobby-g. Either Bobcat hyd. oil, or if I can,t get it. A all season hyd oil from the local farm store. Cheaping out on the oil the basicly RUNS you machine is NUTS, for the cost
