Hello If anyone is seeking the Esso Univis J13 hydraulic oil to replace either Pentosin 7.1 or LHM+ a Co-op agricultural distributor would be a good place to buy. This oil is used by farmers for their hydraulics. I happen to know of one Co-op in Campbellford, Ontario off Highway 30, which is about 45 km east of Peterborough, Ontario Max
