Wood splitter ram cylinder capacity?

[alderman]

On a typical hydraulic wood splitter, what is a ball park number on how much fluid is used to completely extend the ram? I'm thinking somewhere near 1/2 gallon but I have no clue.

I took an average size splitter cylinder. 4” piston x 22” stroke =1.1 gallons roughly.

The last splitter I built I used a 5”x24” cylinder. The oil tank held 10 gallons of hydraulic oil. I forget what the flash point is on the oil but it must be kept cool. My point is make sure your oil capacity is big enough. The 5” bore cylinder if it didn’t split it cut through the wood.

5" bore, 24" stroke, just over 2 gallons.
4" bore, 24" stroke, 1.3 gallons.

I made a spreadsheet with all that info, and how many gpm on the return stroke and such, for when I was having my splitter built.
