Anyone using motor oil in final drive? (instead of gear oil)

Remember that these manual are barely legible and full of translation errors.

Oh yeah, like mine tells me to choose a "plain place" to park if I have trouble with the motorcycle, I don't know about anyone else but I certainly refuse to park in any PLAIN place and insist in parking in a FANCY place as often as I can!

Reminds me of the punchline to the joke ' Why did the blond ride her scooter in circles in Beverly Hills?"

What's the punch line? I haven't heard that one before.

No plain place to park in Beverly Hills

Just wondering. I've noticed some gy6 scooter manuals call for 10w40 or 15w40 engine oil in the rear end, while others call for 80w90 gear oil.

Ive not had the rear end apart on these, I know gear oil works a bit differently. And i figure on a technical side, it could treat gaskets differently; the gaskets on my rear end look to be the same gasket material as my engine up front.

Is anyone here running motor oil in the final drive here?

Using motor oil in the final drive motor instead of gear oil can be a topic of debate, especially since different manuals and manufacturers have varying recommendations. Here's a breakdown to help clarify:

Differences Between Motor Oil and Gear Oil:

Viscosity: Gear oil, such as 80W-90, has higher viscosity compared to motor oil like 10W-40. This means gear oil can provide better protection under high pressure and extreme conditions typically found in gear systems.
Additives: Gear oils contain additives specifically designed to handle the high friction and load of gear systems. Motor oils may lack these additives, which could impact the longevity and performance of the gears.
Manufacturer Recommendations: Always consider the manufacturer’s recommendations first. If the manual specifies gear oil, it's usually because the gears require the specific properties that gear oil provides. Conversely, some lighter-duty systems might be designed to run on motor oil.

Gasket Compatibility: You’re right about the potential differences in how gaskets might respond to different oils. Gear oil can be more corrosive to certain gasket materials compared to motor oil, but if the gaskets are similar to those used in the engine, motor oil might not cause any issues.

Personal Experience: Some users may have successfully used motor oil in their final drives without noticeable issues, but this can vary based on specific use cases and conditions.

Good job for digging up a 10 yo thread in your very first post!
