i may get shot down for this but the local bobcat dealer told me the multi grade motor oil was old school thinking. keeping up with the times, a good quality 10 wt hydraulic with the proper additives was more than adequate. he gave me a list of the additives but it went over my head.i run caterpillar 10 wt hyd in my bobcat mainly because i get it for cost since thats where i work. not because i think it is any better.I run AW 32 Hyd fluid in my 853, I get it at the parts store, hope that help you. dennis
