The instruction to use engine oil came from the days when we used 30W before the days of 15W/40. The proper oil for hydraulics is 10W hydraulic oil, unless you are in a very hot climate when 30W is OK.
Our channel highlights machines from the earliest Holt and Best track-type tractors, equipment from the start of Caterpillar in 1925, up to units built in the mid-1960s.
