Gear oil

I was wondering if you must use gear oil in the final drive on my wifes buddy 125. The reason that I am asking is ,I have a zuma 125 and that wants 10w30 in the final drive as well as the crank case.
Thanks Mark

Yes, you need to use gear oil, 85W-140. There is a huge difference between that and regular oil.

Ok,I will get the proper gear oil.I was just checking because with the zuma 125 ,what ever you use in the crank case you can use in the drive oil.I just thought the motor and trans desighn was so much alike I could use just regular motor oil...Thanks alot for your help....Mark

the owner's guide calls for 140wt gear oil; it does exist, but not common to buy at average auto parts stores, walmarts, etc; most likely you will find 85w-140 in dino or dino/synthetic blends and 75w-140 in full synthetic gear oils; I have Amsoil Severe Gear synthetic 75w-140 gear oil that I used previously in my Rattler 110 and currently in my Buddy 125...great stuff!

whatever you buy in quarts will last a good while since the amount needed for each change is only 90cc...

I am at the store now. The only decent synthetic oil they have is royal purple 75-140
Is that a good choice? Thanks alot .Mark

I think that should be fine.

85w140 conventional is fine if you're changing it out seasonally. For no more than what the transmission consists of you really don't need to use synthetic. Most synthetic oils are made with similar detergent packages as conventional oil, and considering a scooter transmission isn't extremly complex, nor does the fluid get extremly hot or pressurized, save your $$$ and get a name brand conventional. Just get the correct weight and change it seasonally.

With that said, feel free to use synthetic if you feel you must, the main difference is synthetic isn't Dino oil based (again the detergents are similar). I was working at a shop once and spoke to the Vavoline rep, he explained that most "synthetic" oil base is made from paraffins and animal renderings that are super purified, don't take that as the total truth as I don't have it in writing... But it is "man made".

a good point about group III base stocks that can be labeled 'synthetic' in the U.S. since they mimic many characteristics of group IV base stocks (PAO) and group V base stocks (esters), but my Genuine dealer (who sells the Amsoil stuff) told me the majority of Amsoil products are group IV base stocks

those of you who have changed the gear oil before, is there an easy and reliable way to know/pour in 90 cc of the oil?

I use a flavor injector that I got from the grocery store. It's good both for measuring the gear oil and for getting it into that ill-designed port (really, why is it not vertical)?.

The inlet is positioned to be just above half-full compartment.
Basically it doubles as an overflow.

If you are lazy, you can just squeeze gear oil into the inlet, until it flows back out, wait for it to level off and close it up.

I have a 90cc cup from the hospital that is used for collecting samples (it was unused when I got it!).
I use a 60cc syringe to draw up the gear oil from the cup then repeat with 30 cc's.
