sweetwaterfish 15 Report post Posted January 14, 2010 We bought our first hot wash rig to augment our equipment. Is a Hydromax 8.5 GPM dual gun rig built by BCE systems. (Very happy with it!) Its time for the first oil change and wanted your opinions on what to use. The pump is a General Pump TSF 2021. Uses "GP Series 100 oil". What oil/brand would you recommend for this pump? Also, where would I buy it from locally. I've got big jobs scheduled and don't have time for mail order. Share this post Link to post Share on other sites
