Need to top off hydraulic oil in a used machine I bought. Which oil should I use, as I don't know what brand is in it now? CAT website states Cat Hydo Advanced 10. Any other brands that are good alternatives? Thanks for the help!
Chevron Ursa Hydraulic Oil 10W if you want to save money. Or Chevron Delo Torqforce 10w, which is the “official” Chevron alternative for a few bucks more.
Basically any decent quality SAE10W (or ISO 32) hydraulic oil that does not contain the words "universal" or "tractor" in the name of the product or the store selling it.
Thanks for the help! I'll stay away from universal tractor fluid and tractor supply products
