Would like to do a comlete drain and refill on this ’91 Kobelco K909. 55 gal Dealer oil $1,500. Rural King $500. My go to place to get this figured out is the Project Farm channel on YouTube, he tests everything. Nothing on hydraulic oil though. Any danger putting cheapo oil in there? I doubt there’s any difference they way I’m gonna run this, mostly light land clearing and when the weather is good. Thoughts? And anyone got a better idea about getting the cheapest?
