I do them one buy one, because each location holds an unknown total of oil. Its almost 9 gallons and there isn't a single lowest point. The different spots all hold a amount of oil. Kind of like small sumps
@@Carollascompactconstruction gotcha. Sounded like from the video you had buckets under all drain points at once as there was 9 gallons of hydraulic fluid coming out at the same time. I might’ve misunderstood, but I was thinking it was some pressure related thing. Thanks.
