I've heard you can use 15-40WT oil in all cavities. Is this correct? If not what can I use? Thank you, Mark
Simple answer is NO. Final Drives for a start require a TO-4 specification powertrain oil ............ If you want to PM me with your actual Serial Number & an e-mail address I'll download a list of "preferred", "recommended", & "optional" fluids related to ambient temperature for your particular machine.
Try this link: http://www.datateck.com.au/lube/mobil_au/ I find it useful for lots of different machines. Your local oil company might have something similar.
