Perhaps you can explain why the Bobcat dealer service department should not recommend this product for use in Bobcats. Bobcat has gone away from the motor oil thing for hydraulic fluid. Most likely this is because of the reduction/removal of the zinc in motor oil. Have you bothered to look at the specs of this product to see if it is close to Kubota specs?
Well there isn't a Bobcat dealer within 250 mile from me, so no I can't explain what a dealer would or wouldn't recommend.
But I do know how to read a Owners manual and there is no mention of zink just a mention of using 10w 40 motor oil to run in it when Bobcat fluid is not available, but I will look into it.
