Post subject:  The Great Transmission Oil Debate

Hi Folks,
At the risk of igniting a Transmission Oil debate, what's the best currently available Transmission Oil for a 1974/1975 Honda MT250 Elsinore? 1975 user's manual says SAE30 Transmission Oil but current opinion appears to be all over the map.
Thanks for any info.

John Deere Hy Guard 10-30 transmission and hydraulic fluid. Superior for wet clutches, bearings and gears. You won't be disappointed.

Features and Bennefits:

Performance-tested both in lab and in field, and approved by John Deere engineers to meet increased demands for performance and protection of transmissions and hydraulic oils
A polymeric viscosity improver helps Hy-Gard retain its proper viscosity over a wide range of operating temperatures. For Hy-Gard to work efficiently, it must flow readily through any part of the system. Oil that is too light can cause increased wear; too heavy will cause sluggish operation and lower mechanical efficiency.
Reduces wet-brake chatter, assures high braking capacity
Superior wet-clutch performance smoothes clutch operation
High tolerance to water contamination without sludge formation, which could cause filter clogging and hydraulic system malfunction –anti-oxidation capability allows oil to work properly at high temperatures, helping keep transmissions and hydraulic system moving parts clean
Provides protection against rust and corrosion, particularly during low-use periods
Anti-wear additives keep gear and bearing wear to a minimum – extreme pressure film in Hy-Gard helps prevent metal-to-metal contact
Hy-Gard oil can be used in most applications calling for 10W-30 or 5W-30 engine oil for transmission and hydraulic oils.
