[comike27]

I live close to tractor supply what is there version of 10wt or iso 32 hydraulic oil . I only see iso 46 or universal tractor oil it says in the specs 10w -30 weight that doesn’t sound right just trying to get some info .

I use 20w from Rural King. Cam2 brand is $19 per 5 gal bucket or $200 for a 55gal drum
